Google Warns of Hypervisor-Level Ransomware Attacks by UNC3944
Google's Threat Intelligence Group (GTIG) has uncovered a sophisticated cyber-attack campaign by the financially motivated group UNC3944, also known as Scattered Spider. The group's tactics involve rapid, stealthy attacks that compromise vSphere virtualization layers and deploy ransomware directly from the hypervisor level.
GTIG's report reveals that UNC3944 has targeted US retail, airline, and insurance sectors. The group gains initial access through social engineering and infrastructure abuse, breaching IT help desks and accessing Active Directory. Once in, they reset passwords of privileged accounts, access VMware vCenter, and disable backup systems before deploying ransomware. The entire chain of events unfolds in mere hours.
GTIG warns that successful hypervisor-level tactics are being adopted by other ransomware groups, making this a mainstream attack vector. UNC3944 uses legitimate tools like Teleport to maintain covert control. To defend against such attacks, GTIG recommends a three-pillar strategy: proactive configuration, architectural segregation, and advanced SIEM detection.
The UNC3944 group, or Scattered Spider, has shown aggressive and targeted behaviour, focusing on sensitive information for financial gain. While specific targets remain unclear without detailed reports, businesses should be aware of these tactics and implement robust cybersecurity measures, as outlined by GTIG.
