HelloKitty is a ransomware group operated with a great deal of human interaction which has been active since November 2020. The groups’ notoriety comes from infiltrating corporate networks, stealing data, and encrypting systems to demand ransoms to include double extortion. One of their most significant attacks was on CD Projekt Red in February 2021, where they claimed to have stolen source code for games like Cyberpunk 2077 and Witcher 3. In the summer of 2021, they expanded their targets to include the VMware ESXi virtual machine platform using a Linux variant.
