A relatively new ransomware operation named Interlock attacks organizations worldwide, taking the unusual approach of creating an encryptor to target FreeBSD servers.

Launched at the end of September 2024, Interlock has since claimed attacks on six organizations, publishing stolen data on their data leak site after a ransom was not paid. One of the victims is Wayne County, Michigan, which suffered a cyberattack at the beginning of October.

Not much is known about the ransomware operation, with some of the first information coming from incident responder Simo in early October, who found a new backdoor [VirusTotal] deployed in an Interlock ransomware incident.

This week, researchers from cybersecurity firm Trend Micro shared on X that they found an additional sample of the FreeBSD ELF encryptor [VirusTotal] and a sample of the operation's Windows encryptor [VirusTotal].

Trend Micro further said that the threat actors likely created a FreeBSD encryptor as the operating system is commonly used in critical infrastructure, where attacks can cause widespread disruption.

"Interlock targets FreeBSD as it's widely utilized in servers and critical infrastructure. Attackers can disrupt vital services, demand hefty ransoms, and coerce victims into paying," explains Trend Micro.
