MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that advertises cheats and hacks for games like Roblox and Coin Master, aiming to trick users into downloading malicious content. The ML classifier strongly flagged this PDF as malicious, and an external URI was identified pointing to a suspicious download URL. No scripts were extracted from this sample, but the presence of embedded URLs and the lure content suggest a phishing or malware distribution attempt.

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.
