MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document employs a lure related to 'free stuff' and 'game hacks' for popular games like Roblox. It contains multiple embedded URLs that redirect to a suspicious domain, likely to deliver a malicious payload or phish for credentials. The ML classifier strongly indicated maliciousness, and the heuristics confirm the redirection lure.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9988

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.
