T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains multiple embedded URLs and a high-confidence ML classifier flagged it as malicious. The presence of a fake CAPTCHA heuristic indicates a social engineering attempt to trick the user into downloading further content. The document body, though heavily obfuscated, contains references to 'apps-for-free-robux' and URLs related to game hacks, reinforcing the lure.

Heuristics 5
-
Fake CAPTCHA / human verification prompt high SE_FAKE_CAPTCHADocument displays a fake CAPTCHA or human-verification prompt — used to trick users into running commands or pressing keyboard shortcuts
-
Clickable URI points to raw IP address medium PDF_URI_IP_LITERALPDF 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.
-
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
-
External URI info PDF_URIPDF contains an external URL action
-
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/apps-for-free-robux-game-hack
