MalGuard What a hash proves
A digest is a compact identifier calculated from the bytes of a file. Matching a strong digest can support the conclusion that two files have identical content. It does not establish the intent or behavior of that content.
Why reputation needs context
Third-party observations about a digest may be useful, but reports can be outdated, mistaken or incomplete. A previously unreported hash is not proof of safety. A reported hash is evidence that should be interpreted with provenance and context.
A more defensible report
Present identity, provenance, structural observations and reputation as separate fields. Attribute each claim to its evidence and state when the evidence was collected. Where evidence is insufficient, report uncertainty instead of a green verdict.
Limitations
This is an analytical technical note, not a measured malware-detection benchmark. No scanner accuracy or product certification is implied.
