MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple links that are designed to lure users into clicking on them by promising game hacks and generators. The heuristic firings confirm that the PDF links to external URIs and specifically targets users interested in game hacks. No scripts were extracted from this sample, but the embedded URLs are the primary indicators of malicious intent, likely leading to further malware downloads or phishing sites.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9905

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.
