Earlier today, the Health Information Sharing and Analysis Center (Health-ISAC) warning to hospitals and other health care sector entities of a significant acceleration in cyberattacks by the Black Basta ransomware group.

“Recent actionable cyber threat intelligence provided by our partners at federal agencies and the Health-ISAC indicate that this known Russian-speaking ransomware gang is actively targeting the U.S. and global health care sector with high-impact ransomware attacks designed to disrupt operations,” said John Riggi, AHA’s national advisor for cybersecurity and risk. “It is recommended that this alert be reviewed with high urgency and the identified ransomware signatures be immediately loaded into network defenses and threat hunting tools. It also is recommended that the identified cyber risk mitigation practices be implemented as soon as feasible.”
