A new ransomware group, Cicada3301, is specifically targeting VMware ESXi hypervisors. With encryptors for both Windows and ESXi, the group aims to maximize damage in enterprise environments. Researchers suggest Cicada3301 might be linked to the notorious ALPHV/BlackCat, known for its infamous heist on Change Healthcare.

Key Points:

  • Cicada3301 targets VMware ESXi hypervisors with a new ransomware encryptor.
  • The group operates two encryptors: one for Windows devices and another for VMware ESXi.
  • The ransomware operation began in early June, recruiting affiliates by the end of the month.
  • Researchers suspect Cicada3301 might be a rebranded version or a fork of the notorious ALPHV/BlackCat group.
