MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for 'free Robux' and game hacks, directing users to a suspicious URL. The ML classifier strongly indicated maliciousness, and the embedded URL heuristic confirms the redirection to a potentially harmful site. No scripts were extracted, but the document's content and linked URLs suggest a phishing or scam attempt.

Heuristics 3

  • PDF links to a 'free generator / game hack' redirector high PDF_GAME_HACK_REDIRECT_LURE
    PDF's clickable action targets a redirector of the form /app/<id>/<slug>-game-hack — the landing-page shape of a large SEO 'free spins / generator / game hack' lure family that funnels victims through rotating disposable hosts to a malware/scam payload. The multi-link variants also trip ML/link-farm rules; this catches the single-link variants that otherwise score clean.
  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
