MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document employs a common lure of game hacks and cheats to entice users to click on malicious links. The document body and extracted heuristics indicate a redirection to external URLs, including one using an IP address, which likely serve as landing pages for phishing or malware distribution. No scripts were extracted from this sample, but the embedded URLs and the nature of the lure strongly suggest a phishing or social engineering attack.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9995

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.
  • Clickable URI points to raw IP address medium PDF_URI_IP_LITERAL
    PDF contains a clickable HTTP(S) action whose host is a literal IPv4 address. Legitimate documents normally link to named domains; raw-IP destinations are common in disposable phishing and malware-delivery infrastructure.
  • 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.
