MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple links, including one to 'netcdn.co', that are disguised as game hacks and free item generators for Roblox. The ML classifier strongly flagged this PDF as malicious, and the embedded links likely lead to phishing sites or malware downloads. No scripts were extracted, but the document's structure and content indicate a social engineering lure.

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
    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.
