ZETARINK EXPOSED: .ZETARINK Files, HOW-TO-DECRYPT.txt, and a 0.00015 BTC Wallet

You open Documents the way you did yesterday. The first photo should still be 1.jpg. The snapshot 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.ZETARINKXxpV1yCM. 2.png is now 2.png.ZETARINKXxpV1yCM. A small text file named ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt is sitting in the same folder, as if it has always belonged there.

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.

Overview

ZETARINK ransomware locks the files first. Then it keeps the old name and the old type, and hangs .ZETARINK plus a random tail on the end. In the sample used for this page that tail is XxpV1yCM, so the extra ending reads .ZETARINKXxpV1yCM. Then it drops a note named ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt and talks like a recovery desk. Then it changes the desktop wallpaper so the same shout follows you even if you close the folder. The note is a storefront. It shouts ENCRYPTED BY ZETARINK 1.22. It claims all your documents, photos, databases, and other IMP0RTANT files have been encrypted. It claims the files are not damaged, only modified, and that the change is reversible. It says the only 1 way back is a private key and a decryption program. It says any third-party restore will be fatal. Then it tells you to install Tor Browser, connect to a personal link, and enter a personal code. Public copies of that note leave the personal link blank. The personal ID line is blank too. This page will not invent an onion to finish their sentence.

If you are staring at a pile of .ZETARINK files and that text 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.ZETARINKXxpV1yCM. 2.png becomes 2.png.ZETARINKXxpV1yCM. vacation.jpg becomes vacation.jpg.ZETARINKXxpV1yCM. invoice-2026.pdf becomes invoice-2026.pdf.ZETARINKXxpV1yCM. taxes.xlsx becomes taxes.xlsx.ZETARINKXxpV1yCM. You can still read what the file used to be. You cannot open it. Windows may call the type a ZETARINK File and offer a useless “choose an app” box. An app cannot talk locked bytes back into a JPEG. There is 0% chance Photos can open 1.jpg.ZETARINKXxpV1yCM because you picked a viewer.

The second tell is the note. After the files are locked, the malware drops a file whose name follows ZETARINK[random]-HOW-TO-DECRYPT.txt. In this sample that file is ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt. HOW-TO sounds like a guide. DECRYPT sounds like a fix. Put them together and the first English you can still read after the photos break is a sales flyer. The flyer is meant to be opened. It is not meant to be trusted.

The body of that sample is a short costume. It opens =====ENCRYPTED BY ZETARINK 1.22=====. Then ALL YOUR DOCUMENTS, PHOTOS, DATABASES AND OTHER IMP0RTANT FILES HAVE BEEN ENCRYPTED. Then a calm paragraph that says your files are NOT damaged, only modified, and that the modification is reversible. Then the only 1 way: receive the private key and decryption program. Then a fatal warning about third-party software. Then five steps: visit the Tor Project site, download Tor Browser, connect to your personal link, enter your personal code, follow instructions. The personal link is printed as a dash. The personal ID is printed as a dash. That is 100% of the contact on the text file.

The ask does not live in the text file. It lives on a page they brand Zetarink Recovery Portal. That portal tells you the files were encrypted by Zetarink, that you must pay the ransom, and that the payment is 0.00015 BTC to bc1q4vsrn6cwpfxz3y5d4gsp9ksrvl3qrw2fj3ytpm. After you send coin, it asks you to enter a Bitcoin address so they can “verify” the transaction. Then it promises a recovery key and a decryptor download once an administrator confirms payment. This page reprints that wallet because it is already printed. This page will not invent the onion the note left blank. This page will not invent a Session handle, an email inbox, or an extra $ figure on top of the 0.00015 BTC they already named.

That printed ask is unusually small. A number that small can look like leftover copy from a test build. Treat it as a printed ransom anyway. A tiny sticker is still a checkout. Do not send 0.00015 BTC “just to see if the portal answers.” A test payment is still a payment. It still tells them this victim pays.

That is the whole pitch. A locked folder of .ZETARINK names with a random tail. A ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt file that talks like a recovery brief. A wallpaper that repeats the shout. A blank personal link. A blank personal ID. A portal named Zetarink Recovery Portal. A 0.00015 BTC ask. A Bitcoin wallet printed in full. No leak clock. No Session. No email. There is no public free decryptor known for this strain. There is no reason to open a blank Tor portal today because a text file told you to.

The .ZETARINK name is the first warning

Most lockers pick an extension so you notice the change in seconds. This one uses .ZETARINK plus a random string, so two machines can show two different tails. The sample used for this page uses .ZETARINKXxpV1yCM. 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.ZETARINKXxpV1yCM. You can still see 2.png inside 2.png.ZETARINKXxpV1yCM. You can still see the invoice year. 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 .ZETARINKXxpV1yCM 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 portal.

The extra ending also does advertising. Anyone who sees 1.jpg.ZETARINKXxpV1yCM next to ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt can pretend they already have your case. A later fake helper will quote the extension 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. Quoting a different random tail they invented proves even less.

HOW-TO-DECRYPT.txt is a sales floor, not a help file

The ransom note is a plain text file with a name that sounds like documentation. ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt wants the first click after the panic. Plenty of real software drops a how-to. 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. The brand sits in front of the how-to so the file feels personal to your machine. The random tail matches the extra ending on the locked files. That match is branding, not a serial that proves they will help you.

Double-clicking it opens Notepad. That is why a panicked first click feels like opening the help page. It is not help. It is the demand, written so it looks official enough to follow. The filename is built to look like paperwork. ZETARINK. HOW TO. DECRYPT. A .txt ending Windows already trusts. Paperwork is easier to obey than a threat.

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 how-to” when you write the incident down. Copy ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt 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 opening Tor.

ENCRYPTED BY ZETARINK 1.22 is a shout, not a lab report

The first line of the sample is not a diagnosis. It is a headline. ENCRYPTED BY ZETARINK 1.22 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. The 1.22 looks like a product version. It is still costume. A version number on a ransom note is not a changelog you can trust.

The shout is also a brand. Later search ads will quote it. Later “helpers” will paste ZETARINK 1.22 so they sound close to your folder. Anyone can copy a headline. Copying ENCRYPTED BY ZETARINK 1.22 does not mean they can reverse .ZETARINKXxpV1yCM. 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 text 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 a Tor portal they left blank on purpose.

“Not damaged, only modified” is a sales line

The sample spends a whole paragraph sounding kind. Your files are NOT damaged. Your files are modified only. This modification is reversible. That is meant to calm you just enough to keep reading. A person who thinks the photos are already gone may shut the machine down and call someone. A person who thinks the photos are “only modified” is easier to walk toward a portal. The kindness is a funnel.

Then the same paragraph takes the kindness back. The only 1 way to decrypt your files is to receive the private key and decryption program. Any attempts to restore your files with third-party software will be fatal. That pair is the whole shop. First they tell you the files can still be saved. Then they tell you nobody except them can save them. Then they point you at Tor.

You do not need to argue “modified” versus “encrypted” with a text file. You can see 1.jpg.ZETARINKXxpV1yCM will not open. You can see 2.png.ZETARINKXxpV1yCM will not open. That is enough. A reversible claim is not a key in your hand. It is a reason they hope you will follow the next five steps.

The blank personal link is not a puzzle

The instructions say visit the Tor Project site, download Tor Browser, then connect to your personal link. Then the address is a dash. The sample even swears at you not to lose that personal link. Then it says enter your personal code. Then the personal ID is a dash. That is 100% of the contact they printed on the text file. There is no inbox under it. There is no Session handle. There is no extra $ line. There is no onion to copy.

Public copies leave those two lines empty on purpose. This page will not invent an onion to put in that blank. This page will not invent a personal code. If your own file on disk still shows a string on those lines, treat it as evidence for a report, not as a door you should walk through. Do not paste a guessed onion “just to see if the portal loads.” Do not type a made-up ID into a random Tor page that claims to be Zetarink Recovery Portal.

That gap is where copycats work. Someone will publish a long onion and call it the ZETARINK portal. Someone will sell a “connector” that is just more malware. Someone will ask you to run a command so they can “reach the operator on your behalf.” None of that is a reason to finish their sentence. The sample used for this page does not reprint a personal onion. Do not invent one.

0.00015 BTC is still a ransom

The text file never prints a coin total. The portal does. Send 0.00015 BTC to the printed wallet. That is an unusually small sticker. Plenty of lockers print numbers that look like a month of rent. This one prints a number so small it can look like a leftover from a test build, or like a fee they hope you will send without thinking. This page will not invent a lab story around that number. It will say the obvious thing. The printed ask is unusually small. It is still a ransom.

Do not convert 0.00015 BTC into a $ figure in your head and decide it is “not that much.” Do not send it because it feels cheaper than calling someone. Do not send it as a test. Do not send a second amount because a later page claimed the first price expired. The published portal already named 0.00015 BTC. Leave extra $ amounts uninvented. A tiny checkout is how they see whether you will move coin at all.

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. A portal that starts with a locked folder and a printed wallet is not a vendor. A blank onion is not a checkout you should complete. A 0.00015 BTC sticker does not make the rest of that sentence kinder.

The printed wallet is evidence, not a checkout

The portal prints a Bitcoin address in full: bc1q4vsrn6cwpfxz3y5d4gsp9ksrvl3qrw2fj3ytpm. Copy that string into an incident note the way you would copy a plate number. It is how a responder matches this locker to other reports. It is not a payment instruction you should carry out. Do not type it into an exchange “just to see the fee.” Do not paste it into a “wallet checker” a stranger sends. Do not ask a friend to send a tiny test so you can watch the chain.

After you pay, the portal wants another gift. Enter your Bitcoin address below to verify your transaction. That line is not customer service. It is a way to confirm you actually sent coin, and a way to collect a second address they can watch. Do not fill that box. Do not invent an address to “check the form.” A verify field on a criminal portal is still part of the shop.

A later helper will recite that same wallet as if that were a credential. Reciting bc1q4vsrn6cwpfxz3y5d4gsp9ksrvl3qrw2fj3ytpm proves they can read. It does not prove they can open vacation.jpg.ZETARINKXxpV1yCM. If the pitch is “we know the wallet, send $ first,” you are still in the market the ransomware created.

The wallpaper points back to the note

ZETARINK also changes the desktop wallpaper. The glass repeats the brand. ENCRYPTED BY ZETARINK 1.22. ALL YOUR DOCUMENTS, PHOTOS, DATABASES AND OTHER IMPORTANT FILES HAVE BEEN ENCRYPTED. Then a last instruction: find ZETARINK[random]-HOW-TO-DECRYPT.txt and follow instructions. In the sample used for this page that file is ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt.

That wallpaper is not a second incident. It is the same flyer painted on the desktop so you cannot look away. It is meant to make closing Explorer feel useless. It is meant to make the note feel like the only remaining document on the machine. Photograph the wallpaper from a phone if you can do it without opening Tor. Then leave it. You do not need to argue with a background image. The evidence is still the .ZETARINKXxpV1yCM names and ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt.

Notice what the wallpaper does not give you. It does not give you a company, a refund policy, or a $ price. It does not give you an onion. It does not give you the 0.00015 BTC line. It points you back to the text file. The text file points you at Tor. Tor is where they want the rest of the night to happen. That loop is the product.

No leak clock is not kindness

This flyer does not print a leak countdown. It does not say the price doubles after 24 hours. It does not say data goes public after 48 hours. Other families use those fuses. This sample does not. This page will not invent a leak clock to make the story louder. A missing leak line is not proof they copied nothing. It is not proof they copied everything. It is a missing sentence. Leave it missing.

Do not add extra clocks a later helper claims “ZETARINK always uses.” Do not start a personal countdown because a forum post said they only wait two days. The published flyer did not print one. Do not send a small file because a later message offered a test decrypt the original note never printed. Silence is not rude here. Silence is how you stay out of their queue.

Third-party fatal is theater

The note warns that any attempt to restore files with third-party software will be fatal. That line does two jobs. It scares you away from anyone who is not them. It also makes the flyer feel technical, like a sealed case file. It is still a text file in Documents. It is still sitting next to 1.jpg.ZETARINKXxpV1yCM and 2.png.ZETARINKXxpV1yCM.

Leaving the locked names alone is still good advice, for a different reason than they want. Renaming is not a repair. Miracle decryptors from ads are often a second scam. Calling that out does not mean you should obey the rest of the flyer. It does not mean you should skip an official report. It does not mean you should open their blank portal. The people who locked the files do not get a vote on who you tell.

ZETARINK is a locker name, not a product you bought

ZETARINK looks like a tool tag. It looks like something a developer might type. 1.22 looks like a build. This page is not a smear of any ordinary app that happens to share those letters. If a program you actually installed happens to use similar letters, that does not make it this locker. This locker is the one that appends .ZETARINK plus a random tail, drops ZETARINK[random]-HOW-TO-DECRYPT.txt, changes the wallpaper, points you at a blank personal link, and sells a 0.00015 BTC checkout on a page branded Zetarink Recovery Portal.

Do not hunt a random app folder because the flyer used those letters. Do not uninstall a title you like because a ransomware note stole a short name. Do not mail a software vendor as if they ran the lock. The brand on the note is costume. The evidence is the extra ending on 1.jpg.ZETARINKXxpV1yCM, 2.png.ZETARINKXxpV1yCM, and vacation.jpg.ZETARINKXxpV1yCM, plus ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt.

How The Attack Works

The shop is simple once you stop reading it as a rescue. Lock the files. Brand the names with .ZETARINK plus a random tail. Drop ZETARINK[random]-HOW-TO-DECRYPT.txt. Paint the wallpaper with the same shout. Claim the files are only modified. Claim a private key is the only 1 way. Forbid third-party tools. Point recovery at Tor. Leave the personal link blank. Leave the personal ID blank. Put the real checkout on a portal named Zetarink Recovery Portal. Print 0.00015 BTC. Print bc1q4vsrn6cwpfxz3y5d4gsp9ksrvl3qrw2fj3ytpm. Ask for a Bitcoin address after payment. Print no leak clock. Print no Session. Print no email. Then wait for someone else to sell the missing onion.

1. The lock keeps the old name so you recognize the loss

ZETARINK encrypts the files it wants as leverage, then appends .ZETARINK plus a random string. That is why 1.jpg is still readable as 1.jpg.ZETARINKXxpV1yCM, why 2.png is still readable as 2.png.ZETARINKXxpV1yCM, and why invoice-2026.pdf is still readable as invoice-2026.pdf.ZETARINKXxpV1yCM. The operators want you to inventory the damage in seconds. They want you to see the photo, the snapshot, the vacation shot, the invoice, and the tax sheet 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, including a USB stick you forgot was plugged in. Do not plug in a copy “just to check.” Checking is how the extra copy gets the same .ZETARINK ending.

Double-clicking a renamed file does not bring the photo back. The thumbnail may already look broken. Excel may ask for a workbook that is still sitting in the same folder, only the bytes inside are no longer a workbook. That broken open is the first proof. The second proof is the extra ending. Together they are enough. You do not need to open a Tor portal to confirm what you are looking at.

2. The HOW-TO-DECRYPT note takes the first click

Once the names are branded, the malware needs a voice. Other families cover the glass. This one drops a text file. ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt feels like the machine itself left you a note. It feels like a help file you must finish before you can do anything else. That is how a locked photo folder starts to feel like a checkout.

The note is also a hiding trick. While you are reading it, you are not calmly sorting 1.jpg.ZETARINKXxpV1yCM next to 2.png.ZETARINKXxpV1yCM. You are not photographing Explorer. You are not calling someone who can help. The demand is in Notepad. The evidence is in the listing. Read the note as a sales flyer. Then close it. Keep the file. The files next to it still matter more than the shout.

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 give you a coin total. It does not give you a test decrypt. It gives you a tone that says this is already decided, plus a blank personal link it swears at you not to lose. That tone is the product.

3. The wallpaper repeats the shout so you cannot look away

After the folder is branded, the desktop changes. ENCRYPTED BY ZETARINK 1.22. ALL YOUR DOCUMENTS, PHOTOS, DATABASES AND OTHER IMPORTANT FILES HAVE BEEN ENCRYPTED. Find the HOW-TO-DECRYPT note and follow instructions. A wallpaper is harder to close than a text file. It sits behind every window. It makes the incident feel like the operating system itself is talking.

Do not treat the wallpaper as a login. Do not hunt a hidden password in the pixels. Do not “restore default wallpaper” as if that were a decrypt. Changing the picture back does not unlock vacation.jpg.ZETARINKXxpV1yCM. It only removes one piece of evidence if you do it before you photograph the screen. Take the photo first. Then leave the glass alone until you have a clean machine and a real plan.

4. “Reversible” is the costume that makes the shop feel inevitable

The kind paragraph is the lab-coat. Files not damaged. Files only modified. Modification reversible. Only 1 way. Private key. Decryption program. Third-party restore fatal. Each of those sentences is meant to end the conversation you have not even started. Being told the photos can still be saved, but only by them, sounds like you cannot beat this at the kitchen table.

You do not need to argue cryptography with a how-to. You need to stop treating the how-to as a technician. Leave 1.jpg.ZETARINKXxpV1yCM named as it is. Leave 2.png.ZETARINKXxpV1yCM named as it is. Leave taxes.xlsx.ZETARINKXxpV1yCM named as it is. The reversible claim printed in that file is part of the pitch. It is not a recovery procedure.

5. Tor Browser plus a blank personal link is the door they want

The recovery step on the text file is not a key sitting on the desk. It is a browser they tell you to install, then a personal link with no address printed, then a personal code with no value printed. That is the whole door on the note. It looks like support because support uses portals. Criminal shops use portals too, because a page is where a missing onion becomes a negotiation and a locked photo becomes a sample they asked you to attach.

Do not install Tor because ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt said to. Do not hunt a blank portal “just to see.” Do not send a screenshot of Explorer to prove the lock. They already chose the extension. They already chose the note filename. A photo of 1.jpg.ZETARINKXxpV1yCM sitting next to 2.png.ZETARINKXxpV1yCM does not make you a verified customer. It makes you a person still following the flyer.

If someone later says they will “talk to ZETARINK for you” through a portal they found, that is a broker pitch. Brokers need you in the same funnel. You do not owe them a seat. 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 Notepad at midnight.

6. Zetarink Recovery Portal is the checkout

The text file stops at Tor. The money lives on a page titled Zetarink Recovery Portal. Your files have been encrypted by Zetarink. To recover your data, you must pay the ransom. Send 0.00015 BTC to bc1q4vsrn6cwpfxz3y5d4gsp9ksrvl3qrw2fj3ytpm. Enter your Bitcoin address to verify. Wait for an administrator. Then, they say, a recovery key and a decryptor download will appear. That is a storefront. It is not a help desk.

Do not open that portal because the wallpaper told you to find the note, and the note told you to open Tor. Do not open it because the printed ask looks cheap. Do not open it because you want to screenshot the wallet “for the report” from inside their page. You already have the wallet from the published flyer. You already have the note on disk. Walking into their portal is how they learn a victim is live.

7. 0.00015 BTC keeps you from thinking

A tiny printed ask does a special kind of work. It makes paying feel like a rounding error. It makes waiting feel silly. It makes a second opinion feel expensive by comparison. Other families print a number so large you freeze. This one prints a number so small you might shrug and send it. That shrug is the product. The 0.00015 BTC line is still a ransom demand.

Do not add a $ sticker this page did not print as a victim total. Do not start a personal countdown because a later message said “pay 0.00015 BTC now to keep the original deal.” The published portal already named that amount. Leave extra amounts uninvented. Leave the portal unopened. A small number is not a reason to move first.

8. A printed wallet is still a trap

Printing bc1q4vsrn6cwpfxz3y5d4gsp9ksrvl3qrw2fj3ytpm in full makes the shop feel finished. There is no missing line to argue with. There is a place to send coin. There is a verify box waiting after. That completeness is not safety. It is a shorter path to payment. A locker that prints a wallet still can take the coin and send nothing. A locker that prints a tiny amount still can come back later with a larger ask, or with nothing at all.

Do not treat the wallet as a tracking toy. Do not watch the chain for “activity” and then decide the operators are real. Chain activity does not unlock invoice-2026.pdf.ZETARINKXxpV1yCM. It only tells you someone, somewhere, moved coin. That someone might be another victim. It might be a copycat recycling the same string. It is not a reason to join them.

9. Third parties will sell a ZETARINK conversation

After a ransomware incident, search results fill up with companies that say they can decrypt ZETARINK or “all .ZETARINK files.” Some of those shops are ordinary overpriced consultants. Plenty are a second scam. They will quote ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt so they sound close to the case. They will mention ZETARINK 1.22. They will mention 0.00015 BTC. They will mention bc1q4vsrn6cwpfxz3y5d4gsp9ksrvl3qrw2fj3ytpm as if they already called the original crew. They will offer “the real onion” the note left blank. 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 Tor window appear. A Tor window is not Photos opening vacation.jpg again. If a later message skips the original blank portal 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 the onion the public copy left off on purpose.

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 0.00015 BTC send. It does not need a Zetarink Recovery Portal. 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 ZETARINK key” as a second sales pitch.

10. Payment and opening that portal close nothing

Paying a stranger for a private key is not a guarantee. The people who send the note can take the 0.00015 BTC 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. A portal session makes that outcome easier, not harder. You cannot leave a review on a blank Tor page.

Opening a Tor portal for this strain is the free version of the same dead end. 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. Filling a blank personal ID is not useful work. Pasting bc1q4vsrn6cwpfxz3y5d4gsp9ksrvl3qrw2fj3ytpm into an exchange is not useful work. It is the checkout, even when the printed ask is unusually small.

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. Change passwords from a clean device. Watch bank and email alerts. Opening that portal is not useful work. Sending 0.00015 BTC is not useful work. Keep the note. Keep a locked sample. Stay out of their storefront.

What To Do If Your Files End in .ZETARINK

Do not pay. Do not send 0.00015 BTC to bc1q4vsrn6cwpfxz3y5d4gsp9ksrvl3qrw2fj3ytpm. Do not open a blank Tor portal for this strain. Do not invent an onion, a Session ID, an email, or an extra $ figure to finish ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt. Do not type a guessed portal into Tor “just to see.” Do not send a test file. Do not send proof of payment. If you already opened a portal before you found this page, stop there. Do not pay a deposit to “hold the original 0.00015 BTC” for anyone who quotes the note.

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.

1. 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)

2. 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.

1. 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.

   

   DOWNLOAD MALWAREBYTES FOR WINDOWS (FREE)
   
   (The link opens in a new page where your download will start)

2. 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.

   

3. 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.

     

4. 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.

5. Start the Scan

   Click the blue Scan button. Malwarebytes will automatically update its virus database and start checking your computer for malware.

   

6. 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.

   

7. 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.

   

8. 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.)

1. Download HitmanPro

   Click the button below to download HitmanPro. Remember — the scan is free, so you have nothing to lose by checking your PC.

   DOWNLOAD HITMANPRO (FREE SCAN)
   (The link opens in a new page where your download will start)

2. Install HitmanPro

   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.

   

3. 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.

   

   

4. 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.
   

5. 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.

   

6. 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.

1. Download AdwCleaner

   Click the button below to download AdwCleaner — it’s free, portable, and requires no installation.

   

   DOWNLOAD ADWCLEANER (FREE)
   (The link opens in a new page where your download will start)

2. Run AdwCleaner

   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.

   

3. 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“.

   

4. Start the Scan

   Click “Dashboard” on the left side of the window, then click the “Scan” button.

   

5. 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.

   

6. 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.

   

7. 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.

1. Download ESET Online Scanner

   Click the button below to download ESET Online Scanner.

   

   DOWNLOAD ESET ONLINE SCANNER (FREE)
   (The link opens in a new page where your download will start)

2. Run the Installer

   When the download finishes, open your Downloads folder and double-click “esetonlinescanner.exe“.
   

3. 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.
   

4. 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.

   

5. 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.

   

6. 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.

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:

• https://id-ransomware.malwarehunterteam.com/
• https://decrypter.emsisoft.com/
• https://noransom.kaspersky.com/
• https://www.avast.com/ransomware-decryption-tools

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.

1. Download EaseUS Data Recovery Wizard Free.

   You can download EaseUS Data Recovery Wizard Free by clicking the link below.

   

   EASEUS DATA RECOVERY WIZARD FREE DOWNLOAD LINK
   (The above link will open a new page from where you can download EaseUS Data Recovery Wizard)

2. 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.

3. 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.
   

4. 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“.
   

5. 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.
   

6. 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.
   

7. 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.

1. Download ShadowExplorer.

   You can download ShadowExplorer from the below link.

   SHADOW EXPLORER DOWNLOAD LINK
   (This link will open a new web page from where you can download “ShadowExplorer”)

2. Install ShadowExplorer.

   Double-click on the ShadowExplorer-x.x-setup file to start the installation process, then follow the on-screen promts to install this program.
   

3. 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.

   

4. 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 .ZETARINK name exactly as it is. Keep at least one locked sample, including a documented name such as 1.jpg.ZETARINKXxpV1yCM or 2.png.ZETARINKXxpV1yCM. Do not bulk-rename 1.jpg.ZETARINKXxpV1yCM back to 1.jpg, or 2.png.ZETARINKXxpV1yCM back to 2.png, or vacation.jpg.ZETARINKXxpV1yCM back to a normal JPEG, or invoice-2026.pdf.ZETARINKXxpV1yCM back to a normal PDF, or taxes.xlsx.ZETARINKXxpV1yCM back to a spreadsheet. 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 .ZETARINKXxpV1yCM. You do not need to edit it to know what you lost.

Keep ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt with the locked files. Do not “clean up” every copy of the note. Do not fill in an onion so the flyer looks complete. Do not invent a personal code. The blank personal link, or the string 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: the ZETARINK 1.22 shout, the IMP0RTANT line, the blank personal link, the blank personal ID, the Zetarink Recovery Portal name, the 0.00015 BTC ask, and bc1q4vsrn6cwpfxz3y5d4gsp9ksrvl3qrw2fj3ytpm. Those artifacts are evidence. They are not instructions you should carry out.

Do not open a blank Tor portal for this strain. Do not ask a friend to write them “just to see.” A blank personal link is still the people who locked the files, or whoever is standing in that doorway today. If a later message quotes ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt and offers “the real onion,” that is still the same shop. If a later message skips the original blank portal and asks for 0.00015 BTC over a different address, that is still the same shop, or a copycat standing in the same doorway.

Do not send 0.00015 BTC to that wallet. Do not pay. A tiny printed ask is still a ransom. A calm portal is still the people who locked the files. If someone claims they can already decrypt ZETARINK files for a fee because they can recite 0.00015 BTC and bc1q4vsrn6cwpfxz3y5d4gsp9ksrvl3qrw2fj3ytpm, they are selling a report, not a key. If they mention ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt as proof they “already called the crew,” they read the same note you did. 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 .ZETARINK type, decline it. There is no player for that ending.

The Bottom Line

ZETARINK ransomware is a locker with a readable filename, a how-to that shouts ENCRYPT, a wallpaper that repeats the shout, and a checkout that prints 0.00015 BTC. It keeps the old name and appends .ZETARINK plus a random tail. In the sample used for this page, 1.jpg becomes 1.jpg.ZETARINKXxpV1yCM and 2.png becomes 2.png.ZETARINKXxpV1yCM. The note is ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt, matching the pattern ZETARINK[random]-HOW-TO-DECRYPT.txt. It claims the files are only modified, points you at Tor Browser, leaves the personal link blank, leaves the personal ID blank, and sells a Zetarink Recovery Portal that asks for 0.00015 BTC to bc1q4vsrn6cwpfxz3y5d4gsp9ksrvl3qrw2fj3ytpm. It prints no leak clock, no Session handle, and no email. The printed ask is unusually small. There is no public free decryptor known for this strain.

Do not pay. Do not send 0.00015 BTC to that wallet. Do not open a blank Tor portal. Do not invent an onion. Do not rename the pile in bulk. Keep ZETARINKXxpV1yCM-HOW-TO-DECRYPT.txt and a .ZETARINK sample. If you take one sentence with you, take this. A folder of names ending in .ZETARINK plus a random tail, plus a HOW-TO-DECRYPT note with a blank personal link and a 0.00015 BTC wallet, is ransomware on the first sighting. Treat it that way before anyone offers to fill the portal the flyer left empty.
