The US Federal Bureau of Investigation (FBI) says the Ragnar Locker ransomware gang has breached the networks of at least 52 organizations from multiple US critical infrastructure sectors.
This was revealed in a joint TLP:WHITE flash alert published on Monday in coordination with the Cybersecurity and Infrastructure Security Agency.
"As of January 2022, the FBI has identified at least 52 entities across 10 critical infrastructure sectors affected by RagnarLocker ransomware, including entities in the critical manufacturing, energy, financial services, government, and information technology sectors," the federal law enforcement agency said [PDF].
"RagnarLocker ransomware actors work as part of a ransomware family, frequently changing obfuscation techniques to avoid detection and prevention."
The flash alert focuses on providing indicators of compromise (IOCs) organizations can use to detect and block Ragnar Locker ransomware attacks.
IOCs associated with Ragnar Locker activity include info on attack infrastructure, Bitcoin addresses used to collect ransom demands, and email addresses used by the gang's operators.
