MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicates maliciousness, and the document body contains numerous URLs related to free in-game items and hacks, suggesting a phishing or malware distribution lure. The presence of embedded URLs and the overall context point towards an attempt to trick users into downloading further malicious content, likely through a spearphishing attachment vector.

  • 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.
