MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document contains multiple embedded URIs pointing to external resources, including one that uses a raw IP address. The ML classifier strongly indicated maliciousness, and the presence of a 'download button' heuristic suggests a social engineering lure. The document body, though heavily obfuscated, contains references to game-related hacks and currency, reinforcing the phishing pretext.

Heuristics 4

  • Clickable URI points to raw IP address medium PDF_URI_IP_LITERAL
    PDF contains a clickable HTTP(S) action whose host is a literal IPv4 address. Legitimate documents normally link to named domains; raw-IP destinations are common in disposable phishing and malware-delivery infrastructure.
  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
