Introduction
In the ever-evolving landscape of cybersecurity threats, ransomware remains a formidable adversary. Among the latest and most sophisticated is HexaLocker V2, a ransomware variant that has garnered attention for its advanced encryption techniques and data exfiltration strategies.

Understanding HexaLocker V2
HexaLocker V2 is a ransomware strain that encrypts victims’ files and demands a ransom for decryption. It appends the “.hexalocker” extension to encrypted files and leaves a ransom note titled “readme.txt”.

Encryption Mechanism
HexaLocker V2 employs a multi-layered encryption approach:
- Key Generation: A 50-byte random alphanumeric password is generated, accompanied by a 16-byte random salt.
- Key Derivation: The password and salt are processed using the Argon2ID algorithm to derive a 32-byte encryption key.
- File Encryption: Files are encrypted using the ChaCha20 algorithm, a stream cipher known for its speed and security.
- File Extension: Encrypted files are saved with the “.hexalocker” extension, and original files are deleted to prevent recovery.
This robust encryption methodology ensures that, without the decryption key, recovering the original files is virtually impossible.
Data Exfiltration via Skuld Stealer
Before encrypting files, HexaLocker V2 deploys the Skuld Stealer, an open-source information-harvesting tool. Skuld targets sensitive data such as:
- Browser Credentials: Usernames and passwords stored in browsers like Chrome, Firefox, and Opera.
- Browsing History: Records of visited websites and search queries.
- Cryptocurrency Wallet Details: Information related to digital wallets, potentially compromising financial assets.
The collected data is compressed into a ZIP archive and transmitted to the attacker’s server. This double-extortion tactic increases pressure on victims by threatening to leak sensitive information if the ransom is not paid.
Persistence and Obfuscation Techniques
HexaLocker V2 incorporates several mechanisms to maintain its presence and evade detection:
- Persistence: Upon execution, the ransomware copies itself to the “%appdata%\MyApp” directory as “myapp.exe” and creates an AutoRun entry in the Windows registry to ensure it runs on system reboot.
- Obfuscation: The ransomware uses AES-GCM encryption to obfuscate strings and communication channels, making it difficult for security solutions to detect malicious activity.
These techniques enhance the ransomware’s stealth and resilience, complicating removal efforts.
Ransom Note
The ransom note, titled “readme.txt”, is placed on the victim’s desktop and contains the following message:
HexaLocker | Lock. Demand. Dominate. | Since 2024

Detection and Removal
Detecting and removing HexaLocker V2 requires a multi-faceted approach:
- Antivirus Software: Use reputable antivirus programs to scan and remove the ransomware.
- Manual Removal: Delete the ransomware’s executable files and registry entries.
- Data Recovery: Restore files from backups if available.
It’s important to note that removing the ransomware does not decrypt the files.
🛡️ Preventive Measures Against HexaLocker Ransomware
To defend your system and data from threats like HexaLocker, implement the following best practices:
1. Regular Backups
- Maintain offline and offsite backups of all critical data.
- Use versioned backups to restore from a clean point if needed.
- Store backups on external drives or cloud services not connected to your main network.
2. Use Reputable Antivirus & Anti-Malware Tools
- Install well-known antivirus software (e.g., Bitdefender, Kaspersky, Combo Cleaner).
- Enable real-time protection and automatic updates.
- Run full system scans periodically.
3. Be Vigilant with Emails
- Do not open attachments or click links from unknown senders.
- Watch out for phishing emails that mimic legitimate companies.
- Avoid enabling macros in downloaded documents.
4. Download Software from Official Sources
- Avoid cracked software and shady download portals.
- Only use trusted developers and marketplaces.
5. Keep Systems Updated
- Regularly update your operating system, browsers, and applications.
- Apply security patches as soon as they’re released.
6. Restrict User Privileges
- Use non-admin accounts for daily activities.
- Enable User Account Control (UAC) to prevent unauthorized changes.
7. Disable RDP When Not Needed
- Remote Desktop Protocol (RDP) is a common ransomware attack vector.
- Use strong passwords, VPNs, and 2FA if RDP is required.
