Nova Ransomware Decryption and Removal Using Phobos Decryptor

Introduction: A New Player in the Ransomware Battlefield

Cybercrime is evolving faster than ever, and ransomware remains one of the most severe threats to organizations and individuals alike. One of the newest and most technically advanced threats is Nova ransomware, a malicious program designed not just to encrypt files but also to steal sensitive data before launching its full assault.

What is Nova Ransomware?

Nova represents a newly emerged ransomware family that aggressively encrypts files and demands payment for decryption. Victims will notice their files renamed with the .ralord extension and will find a ransom demand note titled “readme.txt” on their desktop.

Nova’s Multi-Tiered Encryption Strategy

Nova uses a complex, layered encryption method, making unauthorized data recovery virtually impossible.

Key Components of the Encryption Process:

Random Key Generation: It starts with generating a 50-character alphanumeric password and a 16-byte salt.
Key Derivation via Argon2ID: The password and salt undergo processing through the Argon2ID hashing function, resulting in a 32-byte encryption key.
Encryption Engine – ChaCha20: Utilizing the fast and secure ChaCha20 cipher, files are locked with high-level encryption.
File Handling: Once encrypted, files are renamed with a .ralord extension, and the originals are permanently deleted to hinder data recovery.

This advanced mechanism ensures that victims cannot access their files without the unique decryption key held by the attackers.

Skuld Stealer: Stealing Data Before Locking Files

Before encrypting files, Nova activates Skuld Stealer, a data-harvesting malware that collects valuable user information. This action transforms Nova into a double-extortion tool, applying extra pressure on victims.

Types of Stolen Information Include:

Saved Browser Credentials: Login details from Chrome, Firefox, and Opera.
Browsing History: Visited websites and search records.
Cryptocurrency Wallet Data: Digital wallet addresses and sensitive keys.

The stolen data is compressed into a ZIP file and transmitted to the attacker’s remote server, creating additional leverage through the threat of public data leaks.

How Nova Avoids Detection and Ensures Persistence?

Nova is engineered to resist removal and to remain active even after system restarts.

Survival and Evasion Techniques:

Persistence Installation: The malicious executable replicates itself as “myapp.exe” under %appdata%\MyApp\ and registers an AutoRun entry in the Windows registry.
Stealth Through Obfuscation: Communications and strings are encrypted using AES-GCM, which shields Nova from many detection mechanisms employed by antivirus software.

These tactics significantly hinder detection and removal efforts, making Nova a long-lasting threat on infected systems.

Decoding the Ransom Note

Victims will find a “readme.txt” file containing a ransom message that claims control over the system and data theft. Here’s a summary of the note:

Confirms that data has been stolen and files encrypted.
Offers a decryption service upon ransom payment.
Provides communication channels through qTox ID and Tor websites.
Warns against tampering with encrypted files.
Threatens to leak stolen data if contact isn’t made promptly.

The note demonstrates not only technical sophistication but also psychological manipulation to coerce compliance.

How to Detect and Eliminate Nova Ransomware?

Eliminating Nova requires a strategic approach combining software tools and manual techniques.

Recommended Steps:

Run a Comprehensive Antivirus Scan: Use trusted antivirus software to detect and eliminate the malware.
Manual File and Registry Cleanup: Delete the malicious executable and associated registry entries from the system.
Restore from Backups: If backups exist, revert files to a safe state before infection.

Note: Removing the ransomware does not decrypt the files; specialized tools are required for decryption.

Proactive Defense: Best Practices to Prevent Nova Ransomware

To avoid falling victim to Nova or similar ransomware, follow these crucial cybersecurity practices:

1. Backup Strategy

Maintain updated offline and offsite backups.
Use versioned backup systems to retrieve uninfected copies.
Store backups on external storage not connected to daily systems.

2. Install Reputable Security Tools

Use renowned antivirus suites like Bitdefender, Kaspersky, or Combo Cleaner.
Enable real-time protection and schedule full scans regularly.

3. Handle Emails With Caution

Do not open unknown attachments or suspicious links.
Be wary of phishing emails imitating trusted brands.
Disable macros in downloaded documents.

4. Download Safely

Only download software from verified platforms.
Avoid cracked software and unofficial sources.

5. Keep Software Updated

Regularly patch OS, browsers, and third-party applications.
Enable automatic updates whenever possible.

6. Minimize User Privileges

Operate with non-administrative accounts when possible.
Turn on User Account Control (UAC) to prevent system changes.

7. Secure Remote Access

Disable RDP if not needed.
If used, secure RDP with VPNs, strong passwords, and two-factor authentication.
