MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text promoting game hacks, specifically for Coin Master and Roblox. The ML classifier strongly indicates maliciousness, and the presence of external URIs suggests an attempt to redirect the user to download malicious content. No scripts were extracted, but the overall pattern points to a social engineering lure for malware distribution.

Heuristics 3

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

  • 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.
