Spook Ransomware

Spook Ransomware Description

Type: Ransomware

The Spook Ransomware is a threat that appears to be deployed against corporate targets predominantly. However, in no way does that mean that individual systems cannot be affected. If the Spook Ransomware manages to infiltrate itself onto the device successfully, it will initiate an encryption process with an uncrackable cryptographic algorithm. All affected files will no longer be accessible.

Exactly like most ransomware, Spook also marks each file it locks by modifying that file's original name. In this case, instead of using a specific word, the threat appends a string of characters - '.PUUEQS8AEJ' as a new file extension. Upon locking all targeted file types, the malware proceeds to deliver two ransom notes with instructions for its victims. Users will be shown identical messages in a pop-up window and inside a text file named 'RESTORE_FILES_INFO.txt'

Spook Ransomware's Demands

The lengthy ransom note states that apart from locking the files stored on the compromised devices, the attackers have also been able to steal vast amounts of sensitive information. The note mentions billing data, financial reports, client details, and more. The cybercriminals threaten to release the information and cause severe repercussions for the affected companies if their demands are not met.

The note also mentions that victims can test the ability of the hackers to restore the encrypted files. They can do so by visiting a dedicated website hosted on the TOR network. There, victims can upload up to 3 files to be decrypted for free. The site is also the only way to contact the attackers.

The full text of the note is:
