A ransomware group is expanding its attacks on U.S. critical infrastructure after hitting more than 500 organizations.
Federal agencies say the ransomware-as-a-service variant has now affected sectors including healthcare, defense, manufacturing, government services, information technology and financial services, says CISA.
The update to advisory AA25-071A marks an increase from the more than 300 victims noted in the March of 2025 version.
Medusa actors use a double-extortion approach that encrypts systems and threatens to release stolen data unless a ransom is paid.
The group operates opportunistically by exploiting unpatched software and has shifted to an affiliate model since early 2023.
Payments to initial access brokers range from $100 to $1 million.
The Healthcare and Public Health sector has been hit especially hard.
Recommended mitigations include timely patching of software and firmware, network segmentation and blocking untrusted access to remote services.
