Medusa ransomware gang claims attacks on prominent Mississippi hospital, New Jersey county

Medusa ransomware claimed responsibility for a major cyberattack that took the University of Mississippi Medical Center offline for nine days and simultaneously impacted Passaic County, NJ, demanding an $800,000 ransom. The attack forced clinical operations to revert to paper, disrupted phone and IT systems, prompted FBI and DHS involvement, and the group—believed to be Russia-linked—threatened to leak stolen data.
