Federal agencies warn of LockBit 3.0 ransomware threat

The Cybersecurity and Infrastructure Security Agency, Federal Bureau of Investigation, Multi-State Information Sharing and Analysis Center and international partners are alerting health care and other critical infrastructure organizations of the threat of LockBit 3.0 ransomware, labeled "Citrix Bleed," which allows cyberthreat actors to bypass password requirements and multifactor authentication measures.
 
“This alert is based upon information voluntarily provided by Boeing Corporation and is an excellent example of cross-sector cyberthreat information sharing for the defense of the nation, against a very significant ransomware threat” said John Riggi, AHA national advisor for cybersecurity and risk. “According to the alert, LockBit 3.0 and its affiliates are exploiting the notorious ‘Citrix Bleed’ vulnerability in the Citrix web application delivery control to harvest credentials, move laterally, defeat multifactor authentication and access data and resources to ultimately steal data and execute high-impact ransomware attacks. Among the many recommendations contained in the alert, it is strongly recommended that all remote-access tools and PowerShell be strictly limited and controlled. As we approach the holidays, it also recommended that increased cyber vigilance and network monitoring be implemented, as our adversaries have repeatedly demonstrated their propensity to attack health care around the holidays — but our network defenders, like our front-line health care heroes, know there are no pauses in our vital missions.”
