HexaLocker Ransomware

HexaLocker is a dangerous ransomware strain that encrypts files and steals sensitive data, using a double-extortion technique to force victims into paying a ransom. Written in Go, this threat has evolved into a formidable malware family, with its most recent variant—HexaLocker V2—integrating an info-stealing component to extract browser and wallet data before encrypting files.

Overview of HexaLocker Ransomware

HexaLocker renames encrypted files by adding the .hexalocker extension and drops a ransom note named readme.txt. The note informs victims that their files have been locked and that private data has been exfiltrated. It demands payment in cryptocurrency and includes a sample decryption offer to prove the attackers’ capabilities.

The V2 version also deploys an info-stealer known as Skuld, which extracts sensitive data like credentials and wallet information. HexaLocker ensures it stays active on infected systems by copying itself to the %appdata%\MyApp directory and adding a registry entry for persistence.

In-Depth Analysis of HexaLocker Ransomware

How Did I Get Infected?

HexaLocker spreads through deceptive phishing emails, infected attachments, and drive-by downloads. It can also exploit vulnerabilities in unpatched software to gain access to a system. Once active, it launches a data stealer to extract sensitive information before encrypting personal and system files.

What Does It Do?

1. Steals Sensitive Data: Gathers credentials, browser cookies, and wallet information using an embedded info-stealer.
2. Encrypts Files: Locks files with strong encryption and changes their extension to .hexalocker.
3. Demands Ransom: Drops a ransom note asking for cryptocurrency payment in exchange for decryption and preventing data leaks.
4. Persists on System: Adds itself to startup to ensure it continues operating after reboots.

Should You Be Worried About Your System?

Yes. HexaLocker poses a significant risk not only by encrypting critical files but also by exfiltrating sensitive data. The double-extortion tactic increases the pressure on victims, with the threat of public data leaks if the ransom isn’t paid. Even if the ransom is paid, there’s no guarantee of file recovery or data safety. Immediate removal is critical.
