Linux KillDisk Ransomware Detection

This YARA rule detects the KillDisk ransomware by identifying specific byte patterns associated with its file encryption routines, file searching mechanisms, and its capability to subvert GRUB (Grand Unified Bootloader). The rule looks for a combination of these patterns within a file, indicating the presence of KillDisk ransomware, which is known for its data wiping and encryption capabilities, often rendering systems unbootable.
