The Scattered Spider cybercrime group launched sophisticated ransomware attacks on July 28, 2025, targeting VMware ESXi servers across critical U.S. infrastructure including retail and airline sectors. The hackers used stolen credentials and social engineering to hijack ESXi hypervisors, encrypting multiple virtual machines at once and causing widespread business disruptions. CISA issued an urgent advisory urging organizations to patch vulnerable ESXi systems and strengthen access controls. Security experts say their evolving tactics make detection increasingly difficult for defenders. The attacks underscore urgent concerns about ransomware threats to virtualized environments that many organizations rely on for core operations.
