Black Berserk Ransomware

The Black Berserk Virus is a dangerous ransomware threat that encrypts victims’ files and demands a ransom for their release. The malware typically spreads through infected email attachments, malicious downloads, and unsafe websites. Once inside a system, it locks files by appending the .rox extension, making them inaccessible. Victims then receive a ransom note titled “RECOVERY INFO.txt”, which instructs them on how to pay for decryption.

How Did I Get Infected?

Primary Infection Methods

Cybersecurity researchers have identified the main infection vectors for Black Berserk Virus:

• Spam Emails & Malicious Attachments: Attackers disguise emails as legitimate messages from known companies or services, tricking victims into opening infected attachments.
• Compromised Websites & Malicious Downloads: Unverified software downloads or cracked programs may contain hidden ransomware.
• Phishing Links: Clicking on fake links in emails, social media, or ads may lead to automatic malware downloads.

Warning: Never open attachments from unknown sources and always verify links before clicking.

Black Berserk Virus – What Does It Do?

Once executed, the Black Berserk Virus performs several malicious actions:

1. File Encryption: It scans your device for specific file types and encrypts them using advanced cryptographic algorithms. The encrypted files receive the .rox extension.
2. Ransom Note Deployment: It creates a ransom note named “RECOVERY INFO.txt” in every affected folder, detailing payment instructions.
3. System Modification: The virus alters Windows Registry keys (Run and RunOnce), ensuring it runs at startup.
4. Data Exfiltration: In some cases, the ransomware may steal sensitive data before encrypting files, threatening victims with leaks unless they pay the ransom.
5. Communication with Remote Servers: Black Berserk may download additional payloads, making further infections possible.

Example of the Ransom Note

Your files have been encrypted!
Limit for free decryption: 3 files up to 5MB (no database or backups)
To decrypt your files, send Bitcoin to the provided wallet address.

What Are .rox Encrypted Files?

Files encrypted by Black Berserk Virus have their original names modified with the .rox extension. For example:

Original File → report.docx
Encrypted File → report.docx.rox

Targeted File Types

• Documents: .docx, .pdf, .pptx
• Images: .jpg, .png
• Videos: .mp4, .avi
• Audio Files: .mp3, .wav
• Archives: .zip, .rar

Unfortunately, decryption is impossible without the private key, which the attackers withhold unless the ransom is paid.
