Observed IOC: Malicious attachment SHA-256 hashes

Description

Detects inbound messages carrying an attachment whose SHA-256 file hash matches a known malicious file observed by the detection-engineering team. IOC list is automatically managed by the IOC pipeline. NOTE: an attachment SHA-256 is itself a file hash, so the embedded literals are SHA-256 of that file hash (hash-of-hash), consistent with the pipeline's hashing convention.
