T1566.001 Spearphishing Attachment
The PDF contains multiple critical heuristic firings indicating it links to known malicious redirectors and game hack lures. The primary lure directs users to a URL associated with 'roblox-hacks-2021-for-robux-game-hack', suggesting a phishing or scam attempt. While no scripts were directly extracted, the PDF structure and embedded URLs point to a malicious redirector chain designed to trick users into visiting potentially harmful sites.

Heuristics 6
-
PDF links to a 'free generator / game hack' redirector critical PDF_GAME_HACK_REDIRECT_LUREPDF'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_LINKPDF 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.
-
Clickable URI uses URL shortener medium PDF_URL_SHORTENER_URIPDF contains a clickable HTTP(S) action whose destination is a URL shortener. This hides the final landing page from static review and is common in phishing redirect PDFs.
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGEOne or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
-
Embedded URL info EMBEDDED_URLOne 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.URL https://netcdn.online/app/431946152/roblox-hacks-2021-for-robux-game-hack In PDF document text
