MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF document contains an embedded URL and a call-to-action button, likely intended to trick the user into downloading a malicious application disguised as a game hack. The heuristic firings indicate the document instructs the user to disable security software, a common tactic to facilitate further malicious activity. While no scripts were explicitly extracted, the ML classifier's high confidence suggests malicious intent, potentially involving exploitation or further payload delivery.

Heuristics 4

  • Security software disable instruction high SE_SECURITY_BYPASS

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
