A hurtful threat designed to lock the data of its victims, the Rever Ransomware can leave its victims with few available options. Indeed, the threat is capable of encrypting a wide array of different file types, including documents, PDFs, photos, archives, databases and others. The strong cryptographic algorithm used in the encryption process makes restoring the affected files practically impossible without knowing the correct decryption keys.
Like most malware of this type, Rever also marks the files it encrypts by appending a new file extension to their original names. However, instead of using a word that could be easily associated with the presence of the threat, Rever generates a new random 8-character string for each locked file. Victims also will notice the presence of a new text file named '@@@ To Restore Your Files.txt' on the desktop of the breached system. Inside the file is a ransom note with instructions from the ransomware's operators.
Judging by the ransom-demanding message, the Rever Ransomware appears to be specifically targeted at corporate entities. The hackers claim to have encrypted several computers and servers, obtained sensitive data from them, and deleted any existing backups of the encrypted files. If victims take too long to contact the cybercriminals, their data will supposedly be leaked to the media and on the Dark Web. The attackers provide a single communication channel via qTOX chat.
