MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document contains a prominent link disguised as a "free generator / game hack" for virtual items, which is a common lure for phishing or malware distribution. The heuristic PDF_GAME_HACK_REDIRECT_LURE specifically flags this type of content. The embedded URL http://netcdn.co/app/431946152/how-to-get-roblox-accessories-for-free-game-hack is identified as a malicious redirector, indicating a high likelihood of leading to a malicious site. No scripts were extracted, but the document's structure and embedded URL strongly suggest a malicious intent to redirect users to a harmful resource.

Heuristics 4

  • PDF links to a 'free generator / game hack' redirector critical 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. CRITICAL on its own: the /app/<id>/<slug>-game-hack path shape is unambiguous scam infra, and the host rotates so a host-list match can't be relied on.
  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • 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
  • 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.
