Meet “Interlock” Ransomware — A New Threat Targeting FreeBSD Servers

In an alarming twist within the ransomware landscape, the new Interlock ransomware operation is making headlines by targeting FreeBSD servers — a rare target in ransomware attacks. Here’s what Wire Tor’s penetration testing services can reveal about this sophisticated new threat impacting organizations globally! 🌐

Launched in late September 2024, Interlock ransomware quickly gained traction by claiming attacks on six organizations. Using a unique FreeBSD ELF encryptor, Interlock is designed to lock down servers, demanding hefty ransoms for decryption keys. When victims don’t pay, their stolen data appears on a data leak site, applying severe double-extortion pressure.

Notable victims include Wayne County, Michigan, which suffered a significant data breach in October. With new samples analyzed by Wire Tor’s expert Pentesters, Interlock demonstrates flexibility in targeting both critical infrastructure and standard Windows environments. 🚔📉

Cybersecurity specialists, Wire Tor Pentesters, examined Interlock’s encryptors and found:

FreeBSD Targeting: Unlike most ransomware that focuses on Linux servers, Interlock was specifically compiled for FreeBSD 10.4, making it a novel threat to critical infrastructure sectors.Windows Encryption: The ransomware’s Windows variant clears Windows event logs, uses DLLs to delete the primary binary, and appends a .interlock extension to encrypted files, leaving a ransom note titled !README!.txt.Dark Web Negotiation: Victims are assigned a Company ID and directed to a Tor negotiation site featuring a chat function for ransom negotiations. Wire Tor can assist clients in understanding this dark web activity and developing robust security postures to mitigate similar threats. 💬

FreeBSD is widely used in critical infrastructure environments, from telecommunications to data servers. By targeting FreeBSD, Interlock can cause devastating disruptions where reliability and uptime are essential. Wire Tor’s Pentesting services can help organizations with FreeBSD infrastructure identify potential entry points and strengthen their defenses against sophisticated ransomware like Interlock. ⚠️

Network Breach: Interlock infiltrates a corporate network, often breaching perimeter defenses and spreading laterally.Double Extortion: Combining data theft with encryption, Interlock threatens to leak sensitive data if the ransom isn’t paid, escalating pressure on the victim.Ransom Demands: With ransoms ranging from hundreds of thousands to millions of dollars, Interlock has the potential to create a significant financial strain on victim organizations. 💵
