Multiple threat actors have capitalized on the leak of Babuk (aka Babak or Babyk) ransomware code in September 2021 to build as many as nine different ransomware families capable of targeting VMware ESXi systems. "These variants emerged through H2 2022 and H1 2023, which shows an increasing trend of Babuk source code adoption," SentinelOne security researcher Alex Delamotte  said  in a report shared with The Hacker News.

"Most reports state that End of General Support (EoGS) and/or significantly out-of-date products are being targeted with known vulnerabilities which were previously addressed and disclosed in VMware Security Advisories (VMSAs)," the virtualization services provider  said .

"In 2021, ESXi 7.0 U2c and ESXi 8.0 GA began shipping with the service disabled by default," VMware added. The announcement comes as unpatched and unsecured VMware ESXi servers around the world have been targeted in a  large-scale   ransomware campaign  dubbed ESXiArgs by likely exploiting a two-year-old bug VMware p
