CISA Warns of Medusa Ransomware Campaign Targeting Over 500 Critical Infrastructure Organizations

The FBI and CISA have issued alerts regarding the Medusa ransomware gang, which has breached more than 500 critical infrastructure organizations in the United States since June 2021. The campaign has resulted in significant disruption to essential services and data exfiltration. Authorities attribute initial access to common vectors such as phishing, RDP compromise, and exploitation of known vulnerabilities. No single software patch addresses the ransomware; mitigation focuses on security best practices.
