Understanding Vook Ransomware

Vook ransomware, een variant van de Djvu-ransomwarefamilie, is een ernstige vorm van malware. It encrypts files and modifies their names by appending a “.vook” extension. Bijvoorbeeld, the image file “1.jpg” becomes “1.jpg.vook”.

The ransomware also generates a ransom note in a text file named “_README.txt”. Cybercriminals often use data-stealing malware before encrypting files.

The Ransom Demand

The ransom note informs victims that all their files have been encrypted using strong encryption and a unique key. It states that the only way to recover these files is by purchasing a decryption tool and a unique key.

The ransom amount is typically $999, with a 50% discount offered if victims contact the attackers within 72 uur. The note strenuously emphasizes that data cannot be restored without payment.

The Mechanics of Ransomware

ransomware, like Vook, executes malicious operations through multi-stage shellcodes, culminating in the final payload responsible for encrypting files. It begins its operation by loading a library named msim32.dll, whose function is unclear.

To avoid detection, ransomware uses loops that prolong execution time, complicating identification by security systems. It also dynamically resolves APIs and creates a duplicate of itself, a tactic known as process hollowing, to increase resilience against interception.

Ransomware Distribution Methods

Threat actors distribute Djvu ransomware via pirated software, gereedschap kraken, en sleutelgeneratoren. Fake websites offering YouTube video downloads are also used to trick users into activating Djvu ransomware.

Ransomware also spreads through malicious files or links sent via email, peer-to-peer (P2P) netwerken, deceptive software updates, downloaders van derden, kwaadaardige advertenties, drive-by-downloads, geïnfecteerde USB-drives, and exploiting vulnerabilities in outdated software.
