MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a prominent lure for a "free generator / game hack" for TikTok followers, directly linking to a suspicious URL. The document body also contains a call-to-action phrase, reinforcing the deceptive nature of the content. While no scripts were extracted, the presence of a high-confidence heuristic for game hack lures and the suspicious URL strongly suggest a phishing or social engineering attack aimed at redirecting users to a potentially malicious site.

Machine Learning

  • Nyx PDF Classifier clean score 0.0718

Heuristics 4

  • 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.
  • 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.
