Storm-1175 is deploying Medusa ransomware within 24 hours of public vulnerability disclosures across healthcare, education, finance, and professional services organizations, exploiting both zero-day and N-day vulnerabilities at high velocity and eliminating the patch window most organizations rely on for protection. No specific CVEs or affected product versions are confirmed in the available source data; this item requires primary source verification against CISA Advisory AA25-071A (Medusa Ransomware, March 2025) and official Microsoft Security Blog coverage before operationalizing specific technical claims. Organizations in targeted sectors should immediately review patch SLA processes for internet-facing systems, implement emergency patch procedures for critical vulnerabilities within 24 hours of disclosure, and query SIEM for behavioral indicators across the mapped ATT&CK chain including T1078, T1059, T1083, T1486, and T1567.
