CryptON Ransomware or Nemesis Ransomware or X3M Ransomware is one of the most dangerous and wide-spread ransomware families. Currently, there are multiple successors of initial virus and several deviations built on another platforms. Cry9, Cry36 and Cry128 Ransomware came from this series. Virus uses mix of AES-256, RSA-2048 and SHA-256 encryption algorithms. Latest discovered version is actually called CryptON Ransomware and uses .ransomed@india.com extension for affected files. Other used suffixes are:

.YOUR_LAST_CHANCE, _x3m, _locked, _crypt, .encrptd, _locked_by_krec, _locked_by_perfect, _r9oj, .nemesis, .v8dp, _garryweber@protonmail.ch, _steaveiwalker@india.com_, _julia.crown@india.com_, _julia.crown@india.com_, _CarlosBoltehero@india.com_, _maria.lopez1@india.com_,
.-juccy[a]protonmail.ch, _[nemesis_decryptor@aol.com].xj5v2, .-sofia_lobster[a]protonmail.ch, _[wqfhdgpdelcgww4g.onion.to].r2vy6, _[qg6m5wo7h3id55ym.onion.to].63vc4, _2irbar3mjvbap6gt.onion.to._, _gebdp3k7bolalnd4.onion._, .fgb45ft3pqamyji7.onion.to._, .losers, .damoclis

Ransomware demands from 0.2 to 1 BitCoin for decryption. It is not recommended to pay the ransom as there are no guarantee malefactors will send decryption key. Depending on version, after encryption CryptON Ransomware creates different text files with instructions to pay the ransom. Recent version uses HOWTODECRYPTFILES.html and it contains following information:

Other possible filenames for ransom notes files are: COMO_ABRIR_ARQUIVOS.txt, ###DECRYPT-MY-FILES###.txt, HOW_OPEN_FILES.html, DECRYPT MY FILE.txt.

How CryptON Ransomware infected your PC

Can be distributed by hacking through an unprotected RDP configuration, using email spam and malicious attachments, fraudulent downloads, exploits, web injections, fake updates, repackaged and infected installers. After infection and encryption, Scarab deletes shadow copies of files, system restore points, disables the Windows Boot Fix, using certain command prompt commands. Virus assigns certain ID with the victims, that is used to name those files and supposedly to send decryption key. In order to prevent infection with this type of threats in future we recommend you to use SpyHunter 5 or Norton Antivirus.
