This rule detects the Minodo backdoor by identifying a combination of specific byte patterns (YARA signatures) within executable files. These patterns correspond to functions responsible for generating system IDs, encrypting and sending data, gathering system information, copying payloads into memory, and executing payloads from temporary locations.
