Dark Ransomware

The Dark Ransomware threat is a variant belonging to the infamous VoidCrypt malware family. Although the threat doesn't seem to have evolved beyond a simple variant when compared to other members of the VoidCrypt Ransomware family, this fact in no way diminishes its capacity to disrupt any infected devices. When activated on the targeted system, the Dark Ransomware will run an encryption routine that will lock a wide array of file types. Indeed, affected users will discover that their documents, PDFs, archives, databases, photos, and more, are no longer accessible.

In addition, each encrypted file will have its name changed drastically. The threat will first add an ID string generated specifically for the victim. Then it will append the 'Darksight@tutanota.com' email address followed by '.dark' as a new file extension. A new text file will also be dropped on the desktop of the breached device. The file will be named 'unlock-info.txt' and inside it, victims will find a ransom note with instructions.

The message left by the cybercriminals states that the hackers will accept ransom payments made using the Bitcoin cryptocurrency only. Victims are expected to establish contact by messaging either the email found in the names of the encrypted files or a reserve address at 'darksight@mailfence.com.' The threat actors seem to be willing to decrypt one file for free. However, victims should choose a file that is less than 1MB in size and it shouldn't contain any important information.
