Proton ransomware continues evolution with latest Zola variant

The latest variant of the Proton ransomware family, Zola, includes privilege escalation measures, a disk overwriting function, and a keyboard-based kill switch. It was first discovered by researchers at the Acronis Threat Research Unit in May. The ransomware changes its encryption scheme and makes it difficult for digital forensics and data recovery. However, its ransom note remains largely unchanged. No known decryptor tool is currently available for the Proton family.
