Comrade Circle Ransomware - How To Remove?

 

Comrade Circle ransomware, first detected on the 8th of October, 2016, pretends to be a Windows update. And, thus, it is already compared with another ransomware threat under the name of Fantom. On the other hand, Comrade Circle trojan virus alludes to the Communist Russia. Its title refers to the soviet custom of addressing one another as comrades. On an interesting note, the hackers behind it promise to grant you with the icon of the comrade Stalin (if you pay them), which is supposed to protect you from the evil. Kind of a bizarre outlook.

About Comrade Circle Ransomware

When Comrade Circle malevolent file-encrypting program starts running on your computer’s system, your computer’s screen is taken over by the fake Windows update message, Configuring critical Windows Updates, while, in fact, the malign program code is encrypting your data files. Comrade Circle crypto malware targets the following multiple files:

.png, .psd, .pspimage, .tga, .thm, .tif, .tiff, .yuv, .ai, .eps, .ps, .svg, .indd, .pct, .pdf, .xlr, .xls, .xlsx, .accdb, .db, .dbf, .mdb, .pdb, .sql, .apk, .app, .bat, .cgi, .com, .exe, .gadget, .jar, .pif, .wsf, .dem, .gam, .nes, .rom, .sav, .cad, .dwg, .dxf, .gis, .gpx, .kml, .kmz, .asp, .aspx, .cer, .cfm, .csr, .css, .htm, .html, .js, .jsp, .php, .rss, .xhtml, .doc, .docx, .log, .msg, .odt, .pages, .rtf, .tex, .txt, .wpd, .wps, .csv, .dat, .ged, .key, .keychain, .pps, .ppt, .pptx, .ini, .prf, .hqx, .mim, .uue, .7z, .cbr, .deb, .gz, .pkg, .rar, .rpm, .sitx, .tar, .gz, .zip, .zipx, .bin, .cue, .dmg, .iso, .mdf, .toast, .vcd, .sdf, .tar, .tax2014, .tax2015, .vcf, .xml, .aif, .if,f .m3u, .m4a, .mid, .mp3 .mpa, .wav, .wma, .3g2, .3gp, .asf, .avi, .flv, .m4v, .mov, .mp4, .mpg, .rm, .srt, .swf, .vob, .wmv, .3d, .3dm, .3ds, .max, .obj, .bmp, .dds, .gif, .jpg, .crx, .plugin, .fnt, .fon, .otf, .ttf, .cab, .cpl, .cur, .deskthemepack, .dll, .dmp, .drv, .icns, .ico, .lnk, .sys, .cfg

.comrade extension is appended to the encrypted files as the additional filename extension, following the regular indicator of the file type. For example, the filename Document.docx is replaced with Document.docx.comrade, which is, of course, unreadable. RESTORE-FILES!_[ID]_.txt (ID here stands for the unique identification number of the infected computer) is the Notepad file, which contains the ransom note. These Notepad files are left in the folders of encrypted data. Once Comrade Circle file encrypter is done with the encryption, the bogus Windows update notification vanishes from your computer’s screen. Instead, the image file of the ransom message, including communist symbolism, is displayed, which encloses the following message, written in poor English, which, in turn, suggest the Russian origin of the hackers:

YOUR FILES ARE ENCRYPTED!
For decryption your files write:

COMRADE CIRCLE

2 BTC (BitCoins) or about 1,259.28 USD is the ransom money which is supposed to be given in exchange of the stolen data. The contact e-mail is recoverfiles@mail2tor.com. After the victim has made the payment using BitCoins, the payment ID is to be sent to the hackers so that they were sure that the transfer has actually happened. But do not do either of these things – do not transfer any payment and do not contact the hackers behind Comrade Circle ransomware, unless you want to have your computer’s system devastated, or, if this is not exactly what is going to happen, you will be living in constant fear of another attack.

Step 3. Restore Comrade Circle Ransomware affected files using Shadow Volume Copies

If you do not use System Restore option on your operating system, there is a chance to use shadow copy snapshots. They store copies of your files that point of time when the system restore snapshot was created. Usually Comrade Circle Ransomware tries to delete all possible Shadow Volume Copies, so this methods may not work on all computers. However, it may fail to do so.

Shadow Volume Copies are only available with Windows XP Service Pack 2, Windows Vista, Windows 7, and Windows 8. There are two ways to retrieve your files via Shadow Volume Copy. You can do it using native Windows Previous Versions or via Shadow Explorer.

a) Native Windows Previous Versions

Right-click on an encrypted file and select PropertiesPrevious versions tab. Now you will see all available copies of that particular file and the time when it was stored in a Shadow Volume Copy. Choose the version of the file you want to retrieve and click Copy if you want to save it to some directory of your own, or Restore if you want to replace existing, encrypted file. If you want to see the content of file first, just click Open.

There are several data recovery programs that might recover encrypted files as well. This does not work in all cases but you can try this:

  • We suggest using another PC and connect the infected hard drive as slave. It is still possible to do this on infected PC though.
  • Download Data Recovery Pro (commercial)
  • Install and scan for recently deleted files. Data Recovery Pro

Note: In many cases it is impossible to restore data files affected by modern ransomware. Thus I recommend using decent cloud backup software as precaution. We recommend checking out Carbonite, BackBlaze, CrashPlan or Mozy Home.
