Threat Database Ransomware Vohuk Ransomware

Vohuk Ransomware

The Vohuk Ransomware is a malware threat that can devastate the data on the computers it infects. By running an encryption routine, the threat will effectively lock the victim's documents, PDFs, images, photos, archives, databases and other file types. The names of the impacted files will be changed completely. The threat will create a random string of characters for the name of each encrypted file, followed by '.Vohuk' as a new file extension.

Victims will be left with two ransom notes. A very brief message will be displayed in an image that the threat will place as a new desktop background. The instructions there simply direct victims toward opening the main ransom note dropped on the system as a text file named 'README.txt.'

The ransom note inside the text file reveals that the operators of the Vohuk Ransomware run a double-extortion operation. The note claims that sensitive data has been collected from the infected systems before the encryption of the files. If the affected organizations refuse to pay the demanded ransom, their data will supposedly be leaked on hacker forums. The threat actors state that they are willing to decrypt two files that do not exceed 2MB in total size, as a demonstration. Victims can contact them via the two email addresses found in the note - '' and ''

The full text of the message dropped by the Vohuk Ransomware as a text file reads:
