How To Remove [Decryptxxx@protonmail.com].XXXX Ransomware

If your documents, pictures, or files are encrypted with a [decryptxxx@protonmail.com].xxxx extension, then your computer is infected with the Dharma ransomware.

Dharma is a file-encrypting ransomware, which encrypts the personal documents found on the victim’s computer, then displays a message which offers to decrypt the data if payment in Bitcoin is made. The instructions are placed on the victims desktop in the decryptxxx@protonmail.com pop-up window or the RETURN FILES.txt text file.

1. How did the [decryptxxx@protonmail.com].xxxx ransomware get on my computer?

The [decryptxxx@protonmail.com].xxxx ransomware is distributed via spam email containing infected attachments or by exploiting vulnerabilities in the operating system and installed software.

Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link embedded inside the email). And with that, your computer is infected with the [decryptxxx@protonmail.com].xxxx ransomware.

This ransomware was also observed attacking victims by hacking open Remote Desktop Services (RDP) ports. The attackers scan for the systems running RDP (TCP port 3389) and then attempt to brute force the password for the systems.

2. What is [decryptxxx@protonmail.com].xxxx ransomware?

• Ransomware family: Dharma Ransomware
• Extensions: [decryptxxx@protonmail.com].xxxx
• Ransom note: RETURN FILES.txt
• Ransom: From $500 to $1500 (in Bitcoins)
• Contact: decryptxxx@protonmail.com

This Dharma ransomware variant restricts access to data by encrypting files with the [decryptxxx@protonmail.com].xxxx extension. It then attempts to extort money from victims by asking for “ransom”, in form of Bitcoin cryptocurrency, in exchange for access to data.

This ransomware targets all versions of Windows including Windows 7, Windows 8.1 and Windows 10. When this ransomware is first installed on a computer it will create a random named executable in the %AppData% or %LocalAppData% folder. This executable will be launched and begin to scan all the drive letters on your computer for data files to encrypt.

Dharma ransomware searches for files with certain file extensions to encrypt. The files it encrypts include important productivity documents and files such as .doc, .docx, .xls, .pdf, among others. When these files are detected, this infection will change the extension to [decryptxxx@protonmail.com].xxxx, so they are no longer able to be opened.

The Dharma ransomware changes the name of each encrypted file to the following format: [decryptxxx@protonmail.com].xxxx.

Files targeted are those commonly found on most PCs today; a list of file extensions for targeted files include:

.sql, .mp4, .7z, .rar, .m4a, .wma, .avi, .wmv, .csv, .d3dbsp, .zip, .sie, .sum, .ibank, .t13, .t12, .qdf, .gdb, .tax, .pkpass, .bc6, .bc7, .bkp, .qic, .bkf, .sidn, .sidd, .mddata, .itl, .itdb, .icxs, .hvpl, .hplg, .hkdb, .mdbackup, .syncdb, .gho, .cas, .svg, .map, .wmo, .itm, .sb, .fos, .mov, .vdf, .ztmp, .sis, .sid, .ncf, .menu, .layout, .dmp, .blob, .esm, .vcf, .vtf, .dazip, .fpk, .mlx, .kf, .iwd, .vpk, .tor, .psk, .rim, .w3x, .fsh, .ntl, .arch00, .lvl, .snx, .cfr, .ff, .vpp_pc, .lrf, .m2, .mcmeta, .vfs0, .mpqge, .kdb, .db0, .dba, .rofl, .hkx, .bar, .upk, .das, .iwi, .litemod, .asset, .forge, .ltx, .bsa, .apk, .re4, .sav, .lbf, .slm, .bik, .epk, .rgss3a, .pak, .big, wallet, .wotreplay, .xxx, .desc, .py, .m3u, .flv, .js, .css, .rb, .png, .jpeg, .txt, .p7c, .p7b, .p12, .pfx, .pem, .crt, .cer, .der, .x3f, .srw, .pef, .ptx, .r3d, .rw2, .rwl, .raw, .raf, .orf, .nrw, .mrwref, .mef, .erf, .kdc, .dcr, .cr2, .crw, .bay, .sr2, .srf, .arw, .3fr, .dng, .jpe, .jpg, .cdr, .indd, .ai, .eps, .pdf, .pdd, .psd, .dbf, .mdf, .wb2, .rtf, .wpd, .dxg, .xf, .dwg, .pst, .accdb, .mdb, .pptm, .pptx, .ppt, .xlk, .xlsb, .xlsm, .xlsx, .xls, .wps, .docm, .docx, .doc, .odb, .odc, .odm, .odp, .ods, .odt

Once your files are encrypted with the [decryptxxx@protonmail.com].xxxx extension, this ransomware will create the RETURN FILES.txt ransom note in each folder that a file has been encrypted and on the Windows desktop.
When the infection has finished scanning your computer it will also delete all of the Shadow Volume Copies that are on the affected computer. It does this so that you cannot use the shadow volume copies to restore your encrypted files.

3. Is my computer infected with [decryptxxx@protonmail.com].xxxx Ransomware?

When Dharma ransomware infects your computer it will scan all the drive letters for targeted file types, encrypt them, and then append the [decryptxxx@protonmail.com].xxxx extension to them. Once these files are encrypted, they will no longer able to be opened by your normal programs. When this ransomware has finished encrypting the victim’s files, it will create a decryptxxx@protonmail.com pop-up ransom note and RETURN FILES.txt text file which includes instructions on how to recover the files.

This is the message that the decryptxxx@protonmail.com pop-up window will display:

4. Is it possible to decrypt files encrypted with the [decryptxxx@protonmail.com].xxxx ransomware?

No. Unfortunately, it’s not possible to recover the files encrypted by this ransomware because the private key which is needed to unlock the encrypted files is only available through the cybercriminals.

Do not pay any money to recover your files. Even if you were to pay the ransom, there is no guarantee that you will regain access to your files.

If you’ve already paid the ransom, immediately contact your bank and your local authorities. If you paid with a credit card, your bank may be able to block the transaction and return your money.
You can also contact the following government fraud and scam reporting websites:

• In the United States, go to the On Guard Online website.
• In Australia, go to the SCAMwatch website.
• In Canada, go to the Canadian Anti-Fraud Centre.
• In France, go to the Agence nationale de la sécurité des systèmes d’information
• In Germany, go to the Bundesamt für Sicherheit in der Informationstechnik website.
• In Ireland, go to the An Garda Síochána website.
• In New Zealand, go to the Consumer Affairs Scams website.
• In the United Kingdom, go to the Action Fraud website.

If your country or region isn’t listed here, we recommend that you contact your country or region’s federal police or communications authority.

It is able to destroy many types of malware that other software tends to miss, without costing you absolutely nothing. When it comes to cleaning up an infected device, Malwarebytes has always been free and we recommend it as an essential tool in the fight against malware.

The first time you install Malwarebytes, you’re given a free 14-day trial of the premium edition, which includes preventative tools like real-time scanning and specific protection from ransomware. After two weeks, it automatically reverts to the basic free version that will detect and clean up malware infections only when you run a scan. It is important to note that Malwarebytes will run alongside antivirus software without conflicts.

   When the scan has completed, you will be presented with a screen showing the malware infections that Malwarebytes has detected. To remove the malicious programs that Malwarebytes has found, click on the “Quarantine Selected” button.
