MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple links and references to game hacks and free in-game currency, specifically targeting Roblox. The heuristic 'PDF_GAME_HACK_REDIRECT_LURE' and the embedded URLs strongly suggest a phishing or malware distribution attempt. While no scripts were explicitly extracted, the nature of the lures and the numerous external links indicate the document's primary purpose is to redirect users to malicious sites, likely for credential harvesting or malware download.

Heuristics 4

  • PDF links to a 'free generator / game hack' redirector critical 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. CRITICAL on its own: the /app/<id>/<slug>-game-hack path shape is unambiguous scam infra, and the host rotates so a host-list match can't be relied on.
  • 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.
