More than 200 victims of Medusa ransomware identified over the last year, CISA says
CISA and the FBI updated their advisory on Medusa ransomware, reporting that the group has compromised more than 500 victims as of April 2026, up from the 300 victims previously disclosed in 2025. Many targets operate in critical infrastructure sectors.
Why it matters: Organizations in critical infrastructure and other sectors face active targeting by Medusa; practitioners should review CISA advisories for indicators of compromise and implement controls aligned with known attack patterns.
