The CryptXXX malware writers have designed a new version which has been reported to contain several drastic improvements in encrypting the files of unsuspecting victims. The ransomware encrypts users’ files after which locks the screen with the ransom message. This is particularly dangerous because users are not able to access their computer to even see what happened to their files. Similar to the previous version, CryptXXX 2.0 (2.006 to be correct) uses a strong encryption cipher to render the files corrupt after which ads a unique identification on the ransom note files. Users who have been infected with the latest version of CryptXXX should be advised that at this point there is no relevant method for decryption of the files encrypted by this version of CryptXXX.

CryptXXX 2.0 Ransomware – How Did I Get It
To successfully infect this computer, the malware is believed to spread via malicious URLs and exploit kits. One of its primary spread methods is believed to be Angler Exploit Kit which has proven its effectiveness over time. Such exploit kits may be spread via:
- HTML files included in archives or opened automatically by other software.
- Redirects to malicious URLs.
- As a result of clicking on a malvertising banner.
- Via spam e-mail messages.
Whatever the distribution method may be, the exploit kit may generate a “hole” in the security and open an unsecured port through which the computer may be infected.
CryptXXX 2.0 Ransomware In Detail
Researchers at Proofpoint(https://www.proofpoint.com/us/threat-insight/post/cryptxxx2-ransomware-authors-strike-back-against-free-decryption-tool) security who have discovered this threat have reported that the authors of Reveton Police Ransomware have went back to their roots. This is because, just like the already outdated Reventon, CryptXXX ransomware locks the screen of the infected PC, preventing the user access to his device:
Also, there is a change in the executables it may create on the infected computers. The ransomware uses names that resemble legitimate Windows processes, creating the files in key Windows folders:
→ In %Temp%:
Svchost.exe
In %System32%:
Rundll32.exe
Not only this but unlike the previous version of CryptXXX, this ransomware also makes the encrypted files to be significantly bigger in size and changing them to such extent that even the previously working Kaspersky Rannoh Decrypter cannot decrypt them. The decrypter requires one original file to establish the encryption pattern, however with the 2.006 version the decryptor provides the following error message:
- “Encrypted file size does not equal to the original”
Furthermore, another improvement in this ransomware besides the ones above is that instead of the older “de_crypt_readme” .bmp, .txt and .html ransom notes and payment sites it uses changed ones whose names are a unique identification for the infected user PC, which is a random alpha numerical number, for example:
Similar to the older version, the ransomware still looks for a wide variety of file types to encrypt:
→ .aes, .ARC, .asc, .asf, .asm, .asp, .avi, .bak, .bat, .bmp, .brd, .cgm, .class, .cmd, .cpp, .crt, .csr, .CSV, .dbf, .dch, .dcu, .dif, .dip, .djv, .djvu, .doc, .DOC, .docb, .docm, .docx, .DOT, .dotm, .dotx, .eml, .fla, .flv, .frm, .gif, .gpg, .hwp, .ibd, .jar, .java, .jpeg, .jpg, .key, .lay, .lay6, .ldf, .max, .mdb, .mdf, .mid, .mkv, .mml, .mov, .mp3, .mp4, .mpeg, .mpg, .ms11, .MYD, .MYI, .NEF, .obj, .odb, .odg, .odp, .ods, .odt, .otg, .otp, .ots, .ott, .PAQ, .pas, .pdf, .pem, .php, .png, .pot, .potm, .potx, .ppam, .pps, .ppsm, .ppsx, .PPT, .pptm, .pptx, .psd, .qcow2, .rar, .raw, .RTF, .sch, .sldx, .slk, .sql, .SQLITE3, .SQLITEDB, .stc, .std, .sti, .stw, .svg, .swf, .sxc, .sxd, .sxi, .sxm, .sxw, .tar, .tar, .bz2, .tbk, .tgz, .tif, .tiff, .txt, .uop, .uot, .vbs, .vdi, .vmdk, .vmx, .vob, .wav, .wks, .wma, .wmv, .xlc, .xlm, .xls, .XLS, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .zip Source:Symantec
Not only this, but CryptXXX ransomware also has renamed the decryption page, naming its decrypter which can be downloaded after paying the ransom “Google Decrypter” instead of the previously named “CryptoWall Decrypter”.
