Net EXPOSED: .net6 Files, Recovery_Instructions.html, and a 72-Hour Price Hike
Written by: Lapain Epuran
Published on:
You open Documents the way you did yesterday. The first photo should still be 1.jpg. The second image should still be 2.png. The vacation shot should still be vacation.jpg. The invoice should still be invoice-2026.pdf. The tax sheet should still be taxes.xlsx. Instead every familiar name has a second ending tacked on. 1.jpg is now 1.jpg.net6. 2.png is now 2.png.net6.
Then you notice a page you did not create. It sits in the same folder, as if it has always belonged there. It is called Recovery_Instructions.html. Recovery sounds like a restore. Instructions sounds like a how-to. An .html ending wants a browser tab, the kind Windows already trusts enough to open without asking twice.
That is the trap, not a glitch.
This page is for the hour those names appear. It is not a miracle key. It is a map of the trap, so the note does not become your incident plan.
Encrypted files after Net. The .net6 names and Recovery_Instructions.html are the tell.
Overview
Net ransomware is a MedusaLocker.C locker. It locks the files first. Then it keeps the old name and the old type, and hangs .net6 on the end. The digit after net may vary. Then it drops Recovery_Instructions.html and talks like a recovery desk. The locker mechanism is hybrid RSA+AES. AES locks the file bytes. RSA wraps the file key so the people who sent the note can claim they alone can unwrap it. The note is a storefront, not a lab report.
If you are staring at a pile of names like 1.jpg.net6 and that HTML note, you are in a ransom incident, not a broken disk and not a Windows pop-up. The folder is the evidence. The note is a checkout. Stay with the folder, not with the script.
The first tell is the rename. In the sample used for this page, 1.jpg becomes 1.jpg.net6. 2.png becomes 2.png.net6. An invoice would look like invoice-2026.pdf.net6. A tax sheet would look like taxes.xlsx.net6. A video would look like family.mp4.net6. You can still read what the file used to be. You cannot open it. Windows may call the type a NET6 File and offer a useless “choose an app” box. An app cannot talk locked bytes back into a JPEG.
The second tell is the note. After the files are locked, the malware drops Recovery_Instructions.html into the same folders. Recovery wants the first click after the panic. Instructions wants you to treat the flyer as a restore procedure. HTML wants a browser, a window Windows already trusts. Put them together and the first English you can still read after the photos break is a sales page. The flyer is meant to be opened. It is not meant to be trusted.
The body of that sample talks like a crisis letter to a company. YOUR PERSONAL ID: and then nothing. YOUR COMPANY NETWORK HAS BEEN PENETRATED. ALL YOUR IMPORTANT FILES HAVE BEEN ENCRYPTED. YOUR FILES ARE SAFE! JUST MODIFIED ONLY. (RSA+AES). ANY ATTEMPT TO RESTORE YOUR FILES WITH THIRD-PARTY SOFTWARE WILL PERMENANTLY DESTROY YOUR FILE. That last word is the note’s own spelling. DO NOT MODIFY ENCRYPTED FILES. DO NOT RENAME ENCRYPTED FILES. NO SOFTWARE AVAILABLE ON INTERNET CAN HELP YOU. WE ONLY HAVE SOLUTION TO YOUR PROBLEM.
Then the second product. WE GATHERED HIGHLY CONFIDENTIAL/PERSORNAL DATA. That is also the note’s own spelling. THESE DATA ARE CURRENTLY STORED ON A PRIVATE SERVER. THIS SERVER WILL BE IMMEDIATELY DESTROYED AFTER YOUR PAYMENT. WE ONLY SEEK MONEY AND DO NOT WANT TO DAMAGE YOUR REPUTATION. IF YOU DECIDE TO NOT PAY, WE WILL RELEASE THIS DATA TO PUBLIC OR RE-SELLER. YOU WILL CAN SEND US 2-3 NON-IMPORTANT FILES AND WE WILL DECRYPT IT FOR FREE TO PROVE WE ARE ABLE TO GIVE YOUR FILES BACK. YOU WILL CAN is the flyer’s grammar. Contact us for price and get decryption software.
The printed Tor chat is gvlay6u4g53rxdi5.onion/8-5fPbb8haRSWCILsmdknwIN7BHklxUW97-BQNqegh7ThKpIKWP513F8ZnQEnxhZt7L. The flyer says that server is available via Tor browser only. It then walks you through downloading Tor Browser and starting a chat. If you cannot use the link, it prints two inboxes: support@gneecher.com and support@3dsservice.com. MAKE CONTACT AS SOON AS POSSIBLE. YOUR DECRYPTION KEY IS ONLY STORED TEMPORARLY. That is the note’s own spelling again. IF YOU DON’T CONTACT US WITHIN 72 HOURS, PRICE WILL BE HIGHER. There is no printed wallet. There is no printed Session handle. There is no extra onion. There is no victim $ figure. This page will not invent those missing pieces so the flyer looks complete.
That is the whole pitch. A locked folder of .net6 names. A Recovery_Instructions.html file that talks like a recovery brief. RSA+AES as the locker costume. A leak-or-sell threat. A 2-3 file tease. One printed Tor chat. Two attacker-claimed inboxes. A 72-hour price hike with no $ amount. A blank Personal ID. There is no public free decryptor known for this strain. There is no reason to mail those inboxes today because an HTML file told you to. There is no reason to open that onion. There is no reason to pay a figure the note never printed.
The .net6 name is the first warning
Most lockers pick an extension so you notice the change in seconds. This one uses .net6. The digit may vary from one copy to the next. The extra cruelty is how readable the listing stays. You do not have to decode anything. You can still see 1.jpg inside 1.jpg.net6. You can still see 2.png inside 2.png.net6. You can still see the invoice year. You can still see the word taxes. The familiar words are still in the folder. The files are not familiar anymore.
Do not treat that readable name as a fix. Do not strip .net6 off the end and expect Photos or Excel to open the file. Do not run a bulk “extension fixer” you found in an ad. The name is a label. The lock is in the content. Editing the label can make a later trusted tool have a harder time matching the file to what it was. Leave the locked copies as they are until you have a clean machine and a plan that does not start in a criminal inbox or a Tor chat.
The extra ending also does advertising. Anyone who sees 1.jpg.net6 next to Recovery_Instructions.html can pretend they already have your case. A later fake helper will quote the .net6 ending back to you as if that were expertise. The extension is public. It is sitting in the folder. Quoting it proves nothing except that they can read a listing.
This is not Microsoft .NET
.net6 looks like a version tag from Microsoft .NET. That is the costume. Microsoft .NET 6 is a real developer platform. Visual Studio, SDK installs, and ordinary app runtimes use names in that family. This locker is not a Microsoft product. It is not a .NET update. It is not a runtime repair. It is not a Visual Studio crash. A folder of 1.jpg.net6 files is ransomware, not a framework upgrade that went wrong.
Do not hunt for a Microsoft support number because the ending looks official. Do not paste the note into a .NET forum and ask which SDK unlocks photos. Do not download a ” .NET 6 repair tool” from an ad that appeared after you searched the extension. Microsoft did not lock the invoice. Microsoft will not mail you a key if you forward Recovery_Instructions.html. Keep the lookalike as an identifier. Then leave Microsoft out of the checkout.
A later helper who says “this is a .NET 6 bug” is selling confusion. A later helper who says they already called Microsoft on your behalf is selling a second lie. The extension borrowed a famous name so the first glance would feel technical instead of criminal. Technical is not honest. It is branding.
Recovery_Instructions.html is a sales floor, not a help page
The ransom note is an HTML file with a name that sounds like documentation. Recovery_Instructions.html wants the first click after the panic. Plenty of real software drops a local HTML help page. This one uses that habit against you. It is meant to be the first English you can still read when the photos will not open.
Double-clicking it opens a browser. That is why a panicked first click feels like opening a restore guide. It is not a restore guide. It is the demand, written so it looks official enough to follow. The filename is built to look like paperwork. Recovery. Instructions. An .html ending Windows already knows how to open. Paperwork in a browser tab is easier to obey than a threat in Notepad.
Keep the file on disk. Then close it. Do not treat it as a set of steps you should follow. Do not tidy the filename. Do not shorten it to “the recovery page” when you write the incident down. Copy Recovery_Instructions.html the way you would copy a serial off a stolen laptop. That string is how a responder matches this locker. It is not a coupon you redeem by mailing support@gneecher.com or support@3dsservice.com, and it is not a coupon you redeem by opening that onion.
YOUR COMPANY NETWORK HAS BEEN PENETRATED is a shout, not a lab report
The first readable banner is not a diagnosis. It is a headline. YOUR COMPANY NETWORK HAS BEEN PENETRATED does the same job a fake breaking-news banner does on a supplement page. It names the disaster in capital letters so the rest of the flyer feels like the only adult in the room. You are supposed to stop thinking and start obeying. ALL YOUR IMPORTANT FILES HAVE BEEN ENCRYPTED piles on the same shout.
The shout is also a brand. Later search ads will quote it. Later “helpers” will paste YOUR COMPANY NETWORK HAS BEEN PENETRATED so they sound close to your folder. Anyone can copy a headline. Copying that banner does not mean they can reverse .net6. It means they read the same note you did, or they read a screenshot of it.
If the shout is sitting in more than one folder, that is normal for this family. Lockers drop the same page in many places so you cannot miss it. Finding five copies is not five incidents. It is one incident with a loud flyer. Keep one clean copy as evidence. You do not need to open every copy. You do not need to compare them in mail to support@gneecher.com.
RSA+AES is the locker mechanism, not a key in your hand
The note claims YOUR FILES ARE SAFE! JUST MODIFIED ONLY. (RSA+AES). Safe is a soothing word. Modified is a smaller word than locked. Together they try to keep you calm enough to follow the next line. RSA+AES is the locker mechanism this family uses as a costume and as a real hybrid lock. AES is the file lock. RSA is how they wrap the file key and then talk as if only their desk can unwrap it. Naming two ciphers does not put a key on your desk.
What the note is actually selling is helplessness. If the lock is “impossible” without their key, then their chat is the only aisle. If the files are “safe,” then paying feels like a small correction instead of a crime. Naming RSA+AES does not prove the implementation. It does not prove they still have a key. It does not prove they will send one if you write those inboxes or open that onion.
People hear AES and go looking for a matching “AES decryptor” in ads. That search is the next trap. A tool that promises to reverse RSA+AES because a ransom note printed the letters is selling the same fear in a different window. Leave the locked files alone. Do not feed 1.jpg.net6 to a mystery app that asked for admin rights because an HTML file named two ciphers.
Third-party restore will destroy is a scare line
The note warns that any attempt to restore files with third-party software will permanently destroy them. It uses PERMENANTLY, the flyer’s own spelling. It also tells you not to modify or rename the encrypted files. Part of that line is ordinary locker advice dressed as a threat. You should not bulk-rename .net6 names, and you should not run a random “decryptor” from an ad. The rest of the line is a lock on the aisle. If every tool except theirs will “ruin” the files, then their chat is the only remaining adult in the room.
That is still attacker copy. A trusted public decryptor, if one ever appears for this strain, does not arrive as a scare paragraph inside Recovery_Instructions.html. It arrives on an official project page that already existed before your incident. The note wants you afraid of every option that is not a payment. Fear of destruction is how they keep you from even looking. You can leave the locked files untouched without mailing the people who locked them.
Do not “test” the scare by editing a copy of invoice-2026.pdf.net6 in a hex editor because a forum said to. Do not run a cracked repair tool that asks you to disable security. The warning on the note is not a lab result. It is a sales paragraph. Keep the files as they are. That is enough. You do not need their permission to wait.
Stolen data leak-or-sell is a second bill
The note does not stop at locked photos. It claims the operators gathered highly confidential and personal data, even while misspelling PERSORNAL. It says that data sits on a private server that will be destroyed after payment. It says that if you do not pay they will release it to the public or to a re-seller. That is double extortion copy. Encryption is the first product. Shame is the second. You are supposed to pay twice in your head: once for the files, once for the silence. Neither purchase is a contract.
Do not pay this leak note. A threat to publish is not proof they have the family photos, the invoice archive, or a client list. Criminals copy leak language because it works on companies and on homes. Answering it still funds the locker. It still does not produce a warranty that a copy was deleted. You cannot audit a “private server” from a Tor chat they told you to start.
The same flyer offers to decrypt 2-3 non-important files for free, to prove they can give the rest back. YOU WILL CAN is the hook written in broken English on purpose. A demo that unlocks a junk PDF does not prove they will unlock vacation.jpg.net6 after a payment. Anyone who already locked the disk can unlock a file they picked. Sending those 2-3 files is how they get a sample, a live inbox, and a victim who is already in the habit of obeying. Do not send the demo. Do not pick “unimportant” files to attach. The offer is the hook. Keep it as a line in the evidence. Do not redeem it.
The Tor chat is checkout, not a help desk
The printed chat path is gvlay6u4g53rxdi5.onion/8-5fPbb8haRSWCILsmdknwIN7BHklxUW97-BQNqegh7ThKpIKWP513F8ZnQEnxhZt7L. Copy that string the way it is. Do not tidy it. Do not invent a shorter one. Do not add a second onion because a comment said a “complete” note needs two. This page reprints the path that is on the flyer. It will not invent an extra one.
The flyer then gives you a how-to. Download Tor Browser. Install it. Open the path. Start a chat. Follow further instructions. That list is checkout dressed as technical support. Tor Browser is a real program. The people who locked 1.jpg.net6 are not the Tor Project. They are not a privacy desk assigned to your case. They want you inside a room they own, on a network they chose, with a thread they can abandon.
Do not install Tor because Recovery_Instructions.html said to. Do not “just open the chat to see the price.” Opening the chat is the product. A price that appears only after you arrive is still a ransom, even when the HTML file never printed a $ figure. If a later helper pastes a different onion and calls it Net support, that is a new ask. Treat it as a new ask. Do not type it anywhere except an incident record.
support@gneecher.com and support@3dsservice.com are checkout
The printed contacts are support@gneecher.com and support@3dsservice.com. Those are the fallback aisle. Two private inboxes put you in a room they own, on accounts they can delete, with a thread they can screenshot and reuse. Email would feel like a ticket. This email is not a ticket. It is how a locked photo becomes a negotiation.
Do not write either address. Do not open a fresh mail account because the note said the Tor link might fail. Do not send a test file to prove you are a real victim. Do not paste a folder listing into a new message. Do not argue about the 72-hour hike as if a discount were available. Those addresses belong to the people who locked the files. Writing them is the product.
The handles are branding, the same way .net6 is branding. Anyone can stand up a lookalike inbox after a wave of locked folders. Writing the first message does not start a warranty. It starts a conversation you cannot enforce. A later helper who says they “already emailed support@gneecher” has not proven a relationship. They read the same flyer.
support@3dsservice.com is attacker-claimed only
support@3dsservice.com looks like a 3-D service desk. That is the costume. Real 3-D printing shops, 3-D scanning labs, and 3-D design firms exist, and some of them use ordinary service-style domains. This inbox is attacker-claimed only. It is not a ticket queue at a modeling studio. It is not a warranty desk for a printer. It is not a reason to call a real 3-D company and ask them to unlock 2.png.net6.
Do not smear a real 3-D firm into this story. Do not hunt for an office, a phone tree, or a “3D service” support page and then forward them the ransom note. Do not leave a one-star review on a legitimate shop because an HTML file borrowed a similar look. The mechanism is impersonation-shaped mail, not a vendor you can call.
A stranger who offers to “talk to 3D Service for you” is still in the same funnel. Keep the address as an identifier in the incident record. Then leave it unused. support@gneecher.com is the same rule with a different costume. Neither one is Microsoft. Neither one is a 3-D shop. Both are checkout.
72 hours is a price hike, not a clock you must meet
The note says that if you do not contact them within 72 hours, the price will be higher. It also says the decryption key is only stored TEMPORARLY, the flyer’s own spelling. That pair is a fuse, not a court date. There is no printed dollar amount on the sample used for this page, and this page will not invent a victim $ figure. A clock without a price is still a checkout trick. You are supposed to feel that waiting is already a mistake. You are supposed to write tonight so the “original” mystery figure does not jump.
Do not treat 72 hours as a real clock you must meet. Do not set a phone alarm. Do not stay up to “beat” a deadline printed by the people who locked the files. The fuse belongs to them. It does not belong to your incident plan. Silence is not rude here. Silence is how you stay out of their queue. A relative, an insurer, or an incident lead can still talk on a phone. The people who locked the files do not get a seat in that call.
A later message that says “your 72 hours are almost up” is still the same shop, or a copycat standing in the same doorway. Anyone can count to three days. Counting does not prove they have a key. It proves they read the flyer. The CISA StopRansomware Guide is blunt about this kind of squeeze. Paying does not ensure the files come back, does not ensure the systems are clean, and does not ensure anyone on the other side keeps a promise.
This is MedusaLocker.C Net, not Bear, not Betelgeuse, not an older *net* locker
The name is a problem because the web is already full of other Nets. This strain is MedusaLocker.C Net. It is the locker that appends .net6 (the digit may vary), drops Recovery_Instructions.html, prints that Tor chat, and points you at support@gneecher.com and support@3dsservice.com. It is not Microsoft .NET. It is not a teddy-bear adware shop. It is not Bear, and it is not Betelgeuse.
Bear and Betelgeuse can share the same locker family and still be a different shop. Those strains use different inboxes. They are not support@gneecher.com. They are not support@3dsservice.com. They are not this Tor path. If a writeup talks about salamati.vip, amniyat.xyz, or owndecrypt@, you are reading a different door. Do not mix the two. A helper who starts from a Bear note and then asks you to mail support@gneecher.com is standing in the wrong doorway on purpose.
Older posts about Skynet, DNET, Killnet, or BLACKNET are also a different file. A name that contains net is not a match. Those pages can wait. The folder in front of you cannot. Keep the family name as an identifier, not as a shopping label. MedusaLocker.C is how responders group this locker. It is not a coupon. It is not a reason to buy a “Medusa decryptor” from the first ad. There is no public free decryptor known for this strain. Until a trusted project publishes one, treat any site that says “we already have the Net key” as a second sales pitch.
How The Attack Works
The shop is simple once you stop reading it as a rescue. Lock the files with a hybrid RSA+AES mechanism. Brand the names with .net6. Drop an HTML note that shouts PENETRATED, claims the files are safe, only modified, and warns that third-party restore will destroy them. Threaten a leak or a re-sale. Offer 2-3 free decrypts. Point the scared person at a Tor chat. Print support@gneecher.com and support@3dsservice.com as the fallback. Light a 72-hour fuse. Leave Personal ID blank. Leave the $ line blank. Then wait for someone else to sell a Microsoft story or a 3-D-shop story on top.
1. The lock keeps the old name so you recognize the loss
Net encrypts the files it wants as leverage, then appends .net6. That is why 1.jpg is still readable as 1.jpg.net6, and why 2.png is still readable as 2.png.net6. The operators want you to inventory the damage in seconds. They want you to see the photo, the invoice, the tax sheet, and the family video in one glance. A coded filename can confuse you. A readable filename makes you feel the theft.
If only one folder looks wrong, do not assume the rest of the disk is safe. Ransomware walks trees. It hits Documents, Desktop, Pictures, Downloads, and any drive letter it can reach. Double-clicking a renamed file does not bring the photo back. The thumbnail may already look broken. A PDF reader may ask for a document that is still sitting in the same folder, only the bytes inside are no longer a document. That broken open is the first proof. The second proof is the extra ending. Together they are enough. You do not need to mail those inboxes to confirm what you are looking at.
2. Recovery_Instructions.html turns a break-in into a ticket
Once the names are branded, the malware needs a voice. Recovery_Instructions.html is that voice. It sits in the same folders as the locked files so the first sort puts help next to harm. On many machines an HTML file with Recovery in the name is the thing you click because it looks like the only file that still speaks English. The body is built to finish before a relative walks into the room. Penetrated. Encrypted. Safe, only modified. RSA+AES. Do not restore with third-party tools. We stole data. We will leak or resell. Send 2-3 files. Open Tor. Or mail these two inboxes. You have 72 hours. Each beat closes a door.
Notice what the note does not give you. It does not give you a company, a refund policy, or a way to prove the other side will ever send a key. It does not fill Personal ID. It does not print a wallet. It does not print a Session handle. It does not print a victim $ figure. It gives you a tone that says this is already decided. That tone is the product. Read the file as a sales flyer. Then close it. Keep it on disk.
3. RSA+AES closes the argument
After the shout, the note rests on RSA+AES as if famous ciphers were a receipt. YOUR FILES ARE SAFE! JUST MODIFIED ONLY is meant to end the conversation you have not even started. Cipher plus private control sounds like math you cannot beat at the kitchen table. Safe plus modified sounds like a reversible edit. It is still a sales paragraph. It is also the locker mechanism. Hybrid RSA+AES is how this family locks the bytes and then talks as if their desk is the only remaining key cabinet. Naming the mechanism is not a recovery procedure.
You do not need to argue cryptography with an HTML file. You need to stop treating the file as a technician. Leave 1.jpg.net6 named as it is. Leave Recovery_Instructions.html where it is. The algorithm printed in that note is part of the pitch. It is not a reason to skip copies that were never mounted. It is not a reason to skip a trusted decryptor project later if one appears.
4. The leak line sells silence
Claiming they gathered confidential data, then threatening to release it to the public or a re-seller, is how they sell silence on top of decryption. Offering to unlock 2-3 non-important files for free is how they make the silence feel testable. Together those lines turn a locked folder into a relationship. Relationships are how payments happen. You do not need that relationship. You need the folder left intact and a plan that does not start in their mail.
Do not attach “unimportant” files. Do not pick the smallest PDF as a demo. Do not pay to stop a leak you cannot verify. If this is a company machine, tell counsel and your incident lead. If this is a home PC, tell the people whose files lived on it. Opening that onion again is not useful work. It is the checkout.
5. The Tor path is the door they want you to walk through
The recovery step in the sample is a Tor chat. Open gvlay6u4g53rxdi5.onion/8-5fPbb8haRSWCILsmdknwIN7BHklxUW97-BQNqegh7ThKpIKWP513F8ZnQEnxhZt7L. Start a chat. Follow further instructions. That is the whole door. It looks like support because support uses chat. Criminal shops use chat too, because a thread is where a mystery price becomes a negotiation and a locked photo becomes a sample they asked you to attach.
Do not open that chat. Do not install Tor “just to see.” Do not send a screenshot of Explorer to prove the lock. They already chose the extension. They already chose the note name. A photo of Recovery_Instructions.html sitting next to 1.jpg.net6 does not make you a verified customer. It makes you a person still following the flyer. If someone later says they will “talk to Net for you” through that same onion, that is a broker pitch. Brokers need you in the same funnel. You do not owe them a seat.
6. Two inboxes are the fallback door
If the onion feels like too much, the note has a softer door. Use the email: support@gneecher.com and support@3dsservice.com. Two addresses look like redundancy, like a real office with a backup desk. They are still the same shop. A second inbox does not make the first one honest. It only gives them another account to abandon if the first one burns.
Treat support@3dsservice.com as attacker-claimed only. Do not turn it into a story about a real 3-D service firm. Do not write support@gneecher.com from a throwaway “just to see.” Do not ask Microsoft about either address. If someone later says they will broker a reply through those same inboxes, that is still the funnel. Report the incident through official desks. Let counsel decide if contact is ever required for a specific legal reason. That decision is not yours to make from the Documents folder at midnight.
7. 72 hours is checkout pressure
Plenty of lockers hide the fuse until you write. This one prints 72 hours up front and says the price will be higher after that. That is not kindness. A printed fuse removes the last excuse for delay. You do not have to “ask how long you have.” You already know the number they want you to fear. The remaining step, in their script, is the Tor chat or the mail. The note has already done the quoting, even without a dollar figure.
Do not convert 72 hours in your head into a reason to pay tonight. The number is theirs. The files are already locked. Another afternoon of panic will not change the bytes in vacation.jpg.net6. Do not “test” a smaller payment to see if they answer. A test payment is still a payment. It still tells them this victim pays. This page will not invent the $ amount they want. You should not invent one either. A later helper who asks for a 50% deposit to “hold the original price” is selling the fuse back to you.
8. Personal ID is blank. Do not invent the rest
The sample leaves YOUR PERSONAL ID blank. That empty line is not a puzzle you should finish. This page will not invent a victim ID. It will not invent a Session handle. It will not invent a wallet. It will not invent a second onion. It will not invent a victim $ figure. A missing string in the copy you are reading is not a challenge. It is a blank. If your own file on disk still shows an empty field there, treat the blank as evidence. Do not fill it because a comment said a “complete” note needs an ID.
Empty fields also give copycats a job. They will sell the missing ID. They will paste a Session handle and call it Net support. They will ask you to mail support@gneecher.com first, then paste what they send. That is still the same shop, or a second shop standing in the same doorway. The published flyer left that line blank. Do not finish it for them.
9. Third parties will sell a Net conversation
After a ransomware incident, search results fill up with companies that say they can decrypt Net or “all .net6 files.” Some of those shops are ordinary overpriced consultants. Plenty are a second scam. They will quote Recovery_Instructions.html so they sound close to the case. They will mention RSA+AES. They will mention 72 hours. They will mention support@gneecher.com as if they already called the original crew. They will ask for a sample file, a remote-access session, or a deposit.
A demo that “unlocks one file” is not proof they can unlock the vacation photo. Anyone can open one junk file they control. Anyone can send you an onion that makes a window appear. A chat window is not Photos opening vacation.jpg again. If a later message skips the original inboxes and asks for coin over ordinary mail, that is still the same market, or a copycat standing in the same doorway. Do not answer. Do not help them invent a wallet the public copy never printed.
A real public decryptor, when one exists, shows up on an official project page that already existed before your incident. It does not need a Tor signup. It does not need support@3dsservice.com. If the pitch is “we can decrypt, pay us first,” you are still in the market the ransomware created. There is no public free decryptor known for this strain. Until a trusted project publishes one, treat any site that says “we already have the Net key” as a second sales pitch.
10. Payment and mailing those inboxes close nothing
Paying a stranger for a private key is not a guarantee. The people who send the note can take the money and disappear. They can send a string that only makes a decryptor show an error. They can come back later and lock the same machine again. They can still leak, or still claim they will, after they are paid. A mail thread makes that outcome easier, not harder. You cannot leave a review on a criminal inbox.
Mailing support@gneecher.com or support@3dsservice.com is the free version of the same dead end. Opening the printed onion is the paid-feeling version with no $ printed yet. There is no public free decryptor known for this strain. Starting a thread does not rebuild a JPEG. It only keeps you in their story while the rest of the disk still needs a real plan. Change passwords from a clean device. Watch bank and email alerts. Opening that HTML file again is not useful work. It is the checkout, even when Personal ID is blank, and even when the 72-hour line is still counting in your head.
What To Do If Your Files End in .net6
Do not email support@gneecher.com or support@3dsservice.com. Do not open gvlay6u4g53rxdi5.onion/8-5fPbb8haRSWCILsmdknwIN7BHklxUW97-BQNqegh7ThKpIKWP513F8ZnQEnxhZt7L. Do not install Tor because the note said to. Do not treat 72 hours as a real clock you must meet. Do not invent a Session handle, an extra onion, a wallet, or a victim $ figure to finish Recovery_Instructions.html. Do not send 2-3 files for a “free decrypt.” Do not pay this leak note. This is not Microsoft .NET. support@3dsservice.com is attacker-claimed only, not a 3-D service desk. If you already sent a message before you found this page, stop there. Do not pay a 50% deposit to “hold the original price” for anyone who quotes the flyer.
STEP 1: Use Rkill to terminate suspicious programs.
In this first step, we will download and run Rkill to terminate suspicious programs that may be running on your computer.
RKill is a program that was developed at BleepingComputer.com that attempts to terminate known malware processes so that your normal security software can then run and clean your computer of infections. When RKill runs it will kill malware processes and then removes incorrect executable associations and fixes policies that stop us from using certain tools.
Download Rkill.
You can download RKill to your computer from the below link. When at the download page, click on the Download Now button labeled iExplore.exe. We are downloading a renamed version of Rkill (iExplore.exe) because some malware will not allow processes to run unless they have a certain filename.
RKILL DOWNLOAD LINK (The above link will open a new page from where you can download Rkill)
Run RKill.
After downloading, double-click the iExplore.exe icon to kill malicious processes. In most cases, downloaded files are saved to the Downloads folder. The program may take some time to search for and end various malware programs.
When it is finished, the black window will close automatically and a log file will open. Do not restart your computer. Proceed to the next step in this guide.
STEP 2: Use Malwarebytes to remove Ransomware and Unwanted Programs
In this second step, we will install Malwarebytes to scan and remove any infections, adware, or potentially unwanted programs that may be present on your computer.
Malwarebytes is one of the most popular and trusted anti-malware tools for Windows — and it’s completely free for removing infections. It catches threats that many antivirus programs miss, including adware, browser hijackers, and trojans. Follow the steps below to scan and clean your PC in just a few minutes.
Download Malwarebytes
Click the button below to download the latest version of Malwarebytes for Windows from the official source. The free version is all you need — it will scan your computer and remove adware, browser hijackers, and other malicious software at no cost.
(The link opens in a new page where your download will start)
Install Malwarebytes
When the download finishes, open your Downloads folder and double-click the MBSetup file. If Windows shows a User Account Control pop-up, click “Yes” to allow the installation.
Follow the On-Screen Prompts to Install Malwarebytes
The setup wizard will walk you through a few quick screens:
Choose where you’re installing the program — “Personal Computer” or “Work Computer” — then click Next.
Malwarebytes will now install on your device. This usually takes under a minute.
When installation is complete, the “Welcome to Malwarebytes” screen will open automatically.
On the final screen, click Open Malwarebytes to launch the program.
Enable “Scan for Rootkits”
Before scanning, turn on rootkit detection so Malwarebytes can find even the most hidden threats. Click the Settings gear icon on the left side of the screen.
In the settings menu, find “Scan for rootkits” and click the toggle so it turns blue.
Done? Click “Dashboard” in the left pane to return to the main screen.
Start the Scan
Click the blue Scan button. Malwarebytes will automatically update its virus database and start checking your computer for malware.
Wait for the Scan to Finish
The scan checks your entire system for browser hijackers and other malicious programs, so it can take several minutes. Feel free to do something else — just check back occasionally to see the progress.
Quarantine the Detected Threats
When the scan is done, you’ll see a list of everything Malwarebytes found — malware, adware, and potentially unwanted programs. Click the “Quarantine” button to remove all of them at once.
Malwarebytes will now remove the malicious files and registry entries and move them safely into quarantine.
Restart Your Computer
Some threats can only be fully removed after a reboot. If Malwarebytes asks you to restart, click Yes. Once you’re logged back in, your PC is clean and you can continue with the next steps in this guide.
STEP 3: Use HitmanPro to remove Rootkits and other Malware
In this third step, while the computer is in normal back, we will download and run a scan with HitmanPro to remove Trojans, rootkits, and other malicious programs.
HitmanPro is a second-opinion scanner — it’s designed to catch what your main antivirus might have missed. Instead of relying on a single detection engine, it checks the behavior of files in the locations where malware usually hides. Anything suspicious gets sent to the cloud, where it’s analyzed by two of the best antivirus engines available: Bitdefender and Kaspersky.
Good news: scanning is completely free, with no limits. You only need a license when it’s time to remove what was found — and even then, you can activate a free one-time 30-day trial to clean your PC at no cost. (A full license is $24.95 per year for 1 PC.)
Download HitmanPro
Click the button below to download HitmanPro. Remember — the scan is free, so you have nothing to lose by checking your PC.
When the download finishes, open your Downloads folder and double-click the file: “hitmanpro.exe” on 32-bit Windows, or “hitmanpro_x64.exe” on 64-bit Windows.
If a User Account Control pop-up asks whether HitmanPro can make changes to your device, click “Yes” to continue.
Follow the On-Screen Prompts
On the HitmanPro start screen, click “Next” to begin the system scan. No lengthy setup required — it goes straight to work.
Wait for the Scan to Finish
HitmanPro will now check your computer for malicious programs. This usually takes just a few minutes thanks to its cloud-based scanning.
Review the Results and Click “Next”
When the scan is done, HitmanPro will show you everything it found. Click “Next” to remove the detected threats.
Click “Activate Free License”
To remove the malicious files, click the “Activate free license” button. This starts your free 30-day trial — no payment details needed — and unlocks the full cleanup.
When the removal is complete, HitmanPro will show a summary of everything it cleaned. Click Next, then click Reboot if prompted. If there’s no reboot prompt, just click Close — your PC is clean.
STEP 4: Use AdwCleaner to remove Malicious Browser Extensions and Adware
In this next step, we will use AdwCleaner to remove malicious browser policies and unwanted browser extensions from your computer.
AdwCleaner is a free on-demand scanner that specializes in adware, browser hijackers, and unwanted toolbars — the exact threats that mainstream antivirus programs often miss. It also includes tools that repair the damage malware leaves behind, like hijacked browser settings and malicious policies. It’s a quick scan that’s well worth running.
Download AdwCleaner
Click the button below to download AdwCleaner — it’s free, portable, and requires no installation.
Open your Downloads folder and double-click the file named “adwcleaner_x.x.x.exe“. There’s no installation — the program starts right away.
If Windows asks whether you want to allow AdwCleaner to run, click “Yes“. When the license agreement appears, click I agree to continue.
Enable “Reset Chrome policies”
This setting removes malicious browser policies — a trick malware uses to lock your browser settings so you can’t change them back. Click “Settings” on the left side of the window, then turn on “Reset Chrome policies“.
Start the Scan
Click “Dashboard” on the left side of the window, then click the “Scan” button.
Wait for the Scan to Finish
AdwCleaner will now check your computer for adware and other malware. This usually takes only a few minutes — it’s one of the fastest scanners around.
Quarantine the Detected Threats
When the scan finishes, AdwCleaner will list everything it found. Click the “Quarantine” button to remove all the malicious items at once.
Click “Continue” to Finish the Cleanup
Save any open work first — AdwCleaner needs to close your open programs before it can clean. When you’re ready, click the “Continue” button.
AdwCleaner will now delete all detected malware from your computer. If it asks you to restart your PC, allow it — your computer will be clean when you log back in.
STEP 5: Perform a final check with ESET Online Scanner
This final step involves installing and running a scan with ESET Online Scanner to check for any additional malicious programs that may be installed on the computer..
ESET Online Scanner is a free second-opinion scanner that performs a deep, full-system check for viruses, trojans, rootkits, and other malware. We use it as the final step because it’s thorough — if anything slipped past the previous scans, ESET will find it. A clean result here means your computer is malware-free.
Download ESET Online Scanner
Click the button below to download ESET Online Scanner.
When the download finishes, open your Downloads folder and double-click “esetonlinescanner.exe“.
Install ESET Online Scanner
On the start screen, select your language from the drop-down menu and click Get started.
On the Terms of use screen, click Accept.
Choose your preferences for the Customer Experience Improvement Program and the Detection feedback system (either choice is fine), then click Continue.
Start a Full Scan
Click Full Scan — this checks your entire computer, not just the common hiding spots.
Select Enable for Detection of Potentially Unwanted Applications — this lets ESET catch adware and bundled junk programs, not just viruses. Then click Start scan.
Wait for the Scan to Finish
ESET will now check every file on your computer. Because it’s a full scan, this can take a while — often an hour or more, depending on how much data you have. Leave it running in the background and check on it from time to time.
Review the Results
When the scan completes, the Found and resolved detections screen appears. Any threats found were automatically cleaned and quarantined — there’s nothing extra you need to do. Click View detailed results if you want to see exactly what was removed.
If ESET found nothing — congratulations, your computer has passed the final check and is malware-free.
STEP 6: Restore the files encrypted by ransomware
Unfortunately, in most cases, it’s not possible to recover the files encrypted by this ransomware virus because the private key which is needed to unlock the encrypted files is only available through the attackers. However, below we’ve listed three options you can use to try and recover your files.
Make sure you remove the malware from your computer first, otherwise, it will repeatedly lock your system or encrypt files. If you suspect that your computer is still infected with malware, you can run a free scan with Emsisoft Emergency Kit.
Option 1: Search a decryption tool for this ransomware
The cybersecurity community is constantly working to create ransomware decryption tools, so you can try to search these sites for updates:
Option 2: Use EaseUS Data Recovery Wizard Free to recover the encrypted files
EaseUS Data Recovery Wizard Free can restore files and repair corrupted files with simple clicks. Its powerful scanning algorithms can identify and retrieve huge file type library, including all of the popular video files, audio files, photos, and document formats. While the free version only allows you to recover 2 GB of data, this can be helpful to see if the recovery is possible and restore back the most important files from your computer.
Download EaseUS Data Recovery Wizard Free.
You can download EaseUS Data Recovery Wizard Free by clicking the link below.
Double-click on the EaseUS Data Recovery Wizard Free setup file.
When EaseUS Data Recovery Wizard Free has finished downloading, double-click on the setup file to install EaseUS Data Recovery Wizard on your computer. In most cases, downloaded files are saved to the Downloads folder.
You may be presented with a User Account Control pop-up asking if you want to allow EaseUS to make changes to your device. If this happens, you should click “Yes” to continue with the EaseUS Data Recovery Wizard Free installation.
Follow the on-screen prompts to install EaseUS Data Recovery Wizard.
When the EaseUS Data Recovery Wizard installation begins, click on the “Install Now” as seen in the image below.
When your EaseUS Data Recovery Wizard installation completes, click the “Start Now” button to start the program.
Select a location to start recovering the encrypted files.
Choose the drive or folder where you are the encrypted files that you want to recover and click “Scan“.
Wait for the EaseUS Data Recovery Wizard scan to complete.
EaseUS Data Recovery Wizard will now scan your computer files that can be restored. This process can take a few minutes, so we suggest you do something else and periodically check on the status of the scan to see when it is finished.
Find the files you want to recover.
When the EaseUS Data Recovery Wizard scan is finished scanning it will show a screen that displays the files that can be recovered. This tool can recover a lot of data, use the “Filter” button to quickly filter specific file types and find the files that you want to recover.
Click the “Preview” button or double-click on a file for a full preview.
Select your files and click “Recover”.
Finally, select the the files you want to recover and click “Recover“. Choose a safe location to save all the files. The free version only allow you to recover 2 GB of data, however, this will allow you to recover the most important files and see if EaseUS Data Recovery Wizard can correctly recover them.
Option 3: Try to restore your files with ShadowExplorer
This ransomware will attempt to delete all shadow copies when you first start any executable on your computer after becoming infected. Thankfully, the infection is not always able to remove the shadow copies, so you should continue to try restoring your files using this method.
Download ShadowExplorer.
You can download ShadowExplorer from the below link.
Double-click on the ShadowExplorer-x.x-setup file to start the installation process, then follow the on-screen promts to install this program.
Select snapshot date.
Open ShadowExplorer and then from the top bar select the drive where the files that you want to save are located, then select from the snapshot available one previous to this infection.
Export the files that you want to recover.
Once you have found a copy of the original file or folder, right-click on it and the select “Export”. A window will prompt you where you want to save the file or folder.
Keep every .net6 name exactly as it is. Do not bulk-rename 1.jpg.net6 back to 1.jpg, or 2.png.net6 back to 2.png, or invoice-2026.pdf.net6 back to a normal PDF, or taxes.xlsx.net6 back to a spreadsheet, or family.mp4.net6 back to a video. Stripping the extra ending is not a repair. It can make a later trusted tool worse, not better. The original name is already sitting in front of .net6. You do not need to edit it to know what you lost. The digit after net may vary. Leave whatever digit you actually have. Do not “correct” it to 6 because a writeup used that sample.
Keep Recovery_Instructions.html with the locked files, and keep at least one .net6 sample next to it. Do not “clean up” every copy of the note. Do not fill Personal ID so the flyer looks complete. The blank, or the extra text on your disk, is part of how you prove this was this strain and not a different locker that only sounds similar. Keep the contact marks as identifiers: support@gneecher.com, support@3dsservice.com, the printed Tor path, the RSA+AES line, the 72-hour hike, and the 2-3 file offer. Those artifacts are evidence. They are not instructions you should carry out.
Do not email those inboxes. Do not open that onion. Do not ask a friend to write them “just to see.” A calm address is still the people who locked the files. A 3-D-looking domain is still attacker-claimed mail. If a later message quotes Recovery_Instructions.html and offers “the real chat ID,” that is still the same shop. If a later message skips the original inboxes and asks for coin over a different address, that is still the same shop, or a copycat standing in the same doorway.
Do not treat 72 hours as a clock you must meet. Do not pay this leak note. Do not send the 2-3 file demo. This is not Microsoft .NET. If someone claims they can already decrypt Net files for a fee because they can recite RSA+AES and the two support inboxes, they are selling a report, not a key. If they mention MedusaLocker.C as proof they “already called the crew,” they read a family name. This is MedusaLocker.C Net, not Bear, not Betelgeuse, and not an older Skynet, DNET, Killnet, or BLACKNET post. Do not answer. Do not complete their checkout. Do not help them fix the flyer.
If Windows still offers to pick an app for the .net6 type, decline it. There is no player for that ending. 100% of those choose-an-app boxes are a dead end.
The Bottom Line
Net ransomware is a MedusaLocker.C locker with a readable filename, an HTML note, a printed Tor chat, and a 72-hour price hike. The locker mechanism is hybrid RSA+AES. It keeps the old name and appends .net6. The digit may vary. 1.jpg becomes 1.jpg.net6. The note is Recovery_Instructions.html. It claims the company network was penetrated, says the files are safe, only modified, warns that third-party restore will destroy them, claims stolen data, threatens to leak or resell if unpaid, and offers 2-3 non-important files as a free decrypt. It points you at gvlay6u4g53rxdi5.onion/8-5fPbb8haRSWCILsmdknwIN7BHklxUW97-BQNqegh7ThKpIKWP513F8ZnQEnxhZt7L, then at support@gneecher.com and support@3dsservice.com. Personal ID is blank. There is no printed wallet, no Session handle, no extra onion, and no victim $ figure. This page will not invent those missing pieces. There is no public free decryptor known for this strain.
Do not email support@gneecher.com or support@3dsservice.com. Do not open that Tor chat. Do not treat 72 hours as a real clock. Do not pay this leak note. Do not rename the pile in bulk. This is not Microsoft .NET. support@3dsservice.com is attacker-claimed only. Keep Recovery_Instructions.html and a .net6 sample. If you take one sentence with you, take this. A folder of names ending in .net6, plus Recovery_Instructions.html, is ransomware on the first sighting. It is MedusaLocker.C Net, not a .NET update and not an older *net* locker. Treat it that way before anyone offers to fill the blank ID line.
10 Rules to Avoid Online Scams
Here are 10 practical safety rules to help you avoid malware, online shopping scams, crypto scams, and other online fraud. Each tip includes a quick “if you already got hit” action.
Stop and verify before you click, log in, download, or pay.
Most scams win by creating urgency. Verify using a trusted method: type the website address yourself, use the official app, or call a known number (not the one in the message).
If you already clicked: close the page, do not enter passwords, and run a malware scan.
Keep your operating system, browser, and apps updated.
Updates patch security holes used by malware and malicious ads. Turn on automatic updates where possible.
If you saw a scary “update now” pop-up: close it and update only through your device settings or the official app store.
Use layered protection: antivirus plus an ad blocker.
Antivirus helps block malware. An ad blocker reduces scam redirects, phishing pages, and malvertising.
If your browser is acting weird: remove unknown extensions, reset the browser, then run a full scan.
Install apps, software, and extensions only from official sources.
Avoid cracked software, “keygens,” and random downloads. During installs, choose Custom/Advanced and decline bundled offers you do not recognize.
If you already installed something suspicious: uninstall it, restart, and scan again.
Treat links and attachments as untrusted by default.
Phishing often impersonates delivery services, banks, and popular brands. If it is unexpected, do not open attachments or log in through the message.
If you entered credentials: change the password immediately and enable 2FA.
Shop safely: research the store, then pay with protection.
Be cautious with brand-new stores, “closing sale” stories, and prices that make no sense. Prefer credit cards or PayPal for dispute options. Avoid wire transfers, gift cards, and crypto payments.
If you already paid: contact your card issuer or PayPal quickly to dispute the transaction.
Crypto rule: never pay a “fee” to withdraw or recover money.
Common patterns include fake profits, then “tax,” “gas,” or “verification” fees. Another is a “recovery agent” who demands upfront crypto.
If you already sent crypto: stop paying, save evidence (wallet addresses, TXIDs, chats), and report the scam to the platform used.
Secure your accounts with unique passwords and 2FA (start with email).
Use a password manager and unique passwords for every account. Enable 2FA using an authenticator app when possible.
If you suspect an account takeover: change passwords, sign out of all devices, and review recent logins and recovery settings.
Back up important files and keep one backup offline.
Backups protect you from ransomware and device failure. Keep at least one backup on an external drive that is not always connected.
If you suspect infection: do not connect backup drives until the system is clean.
If you think you are a victim: stop losses, document evidence, and escalate fast.
Move quickly. Speed matters for disputes, account recovery, and limiting damage.
Stop payments and contact: do not send more money or respond to the scammer.
Call your bank or card issuer: block transactions, replace the card if needed, and start a dispute or chargeback.
Secure your email first: change the email password, enable 2FA, and remove unfamiliar recovery options.
Secure other accounts: change passwords, enable 2FA, and log out of all sessions.
Scan your device: remove suspicious apps or extensions, then run a full malware scan.
Save evidence: screenshots, emails, order pages, tracking pages, wallet addresses, TXIDs, and chat logs.
Report it: to the payment provider, marketplace, social platform, exchange, or wallet service involved.
These rules are intentionally simple. Most online losses happen when decisions are rushed. Slow down, verify independently, and use payment methods and account controls that give you recourse.
