A post hash is a unique identifier for a specific bulletin, post, or claim entry. In threat intelligence, it helps analysts refer to one exact item without relying on a title, screenshot, or copied text, which can change or be duplicated across sites.
This matters because cybercrime forums and extortion pages often host the same message in many places. A post hash lets defenders track the original record, compare updates, and avoid confusion between similar claims. In ransomware cases, it can support incident review by linking logs, intelligence feeds, and internal notes to one verified post, even when the underlying allegation is still unconfirmed.
