MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded links that redirect to malicious infrastructure, specifically promoting 'game hacks' and 'free generators'. The primary link, http://netcdn.tw/app/406889139/hack-spin-coin-master-2021-game-hack, is identified as a malicious redirector. While no scripts were explicitly extracted, the PDF structure and embedded URLs suggest an attempt to trick users into visiting potentially harmful sites, likely as a lure for further malware delivery or phishing.

Heuristics 3

  • 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.
  • 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.
