Black Berserk Ransomware

The Black Berserk Virus is a dangerous ransomware infection that encrypts files on a victim’s computer and demands a ransom payment for decryption. This malicious software primarily spreads through email attachments and unsafe downloads, often disguised as legitimate files to evade detection.

Once Black Berserk infiltrates a system, it encrypts critical files and appends the .rox extension, rendering documents, images, videos, and other file types inaccessible. Victims are then presented with a ransom note titled “RECOVERY INFO.txt”, which provides payment instructions for file recovery.

What Does Black Berserk Virus Do?

Once it infiltrates the system, Black Berserk executes several harmful activities:

1. File Encryption:
   • Scans the system for files and encrypts them with the .rox extension.
   • Commonly targeted files include documents, media, and compressed archives.
2. Ransom Note Delivery: Displays the ransom note "RECOVERY INFO.txt" with payment instructions.
3. Data Exfiltration: In some cases, sensitive data may be stolen before encryption.
4. System Modifications:
   • Alters Windows Registry keys (Run and RunOnce) to ensure persistence.
   • Injects malicious code into essential directories, including:
     • %Local%
     • %Temp%
     • %AppData%
     • %SystemDrive%
5. Communication with Command-and-Control (C2) Server: Sends information about the infected system to the attacker.

The ransom note often reads:

"Your files have been encrypted with Black Berserk Virus. To recover them, send payment to the provided Bitcoin address. Limit for free decryption: 3 files up to 5MB (no database or backups)."

Understanding .rox Encrypted Files

Black Berserk ransomware targets a wide range of file types, appending the .rox extension. Commonly encrypted file formats include:

• Documents: .docx, .pdf, .pptx
• Images: .jpg, .png, .bmp
• Videos: .mp4, .avi, .mkv
• Audio: .mp3, .wav, .ogg
• Archives: .zip, .rar, .7z

Example: "FamilyPhoto.jpg" becomes "FamilyPhoto.jpg.rox"

These files cannot be accessed without the decryption key held by the attackers.
