MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document contains embedded links and a call-to-action phrase, attempting to trick users into downloading files by promising in-game currency or cheats. The ML classifier strongly indicated maliciousness, and multiple URIs point to potentially malicious content hosted on external domains and an IP address. No scripts were extracted, but the document's structure and embedded links suggest a phishing or malware distribution attempt.

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.
