T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

This PDF document employs a fake CAPTCHA lure to trick users into downloading files, likely malicious payloads. The document body and extracted URLs promote downloads for games and hacks, such as 'minecraft-free-download-linux-game-hack' and various 'robux' or 'coin master hack' related links. The presence of external URIs and a high ML classifier score indicate malicious intent.

Heuristics 5

Fake CAPTCHA / human verification prompt high SE_FAKE_CAPTCHA

Document 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_LITERAL

PDF 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_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
External URI info PDF_URI

PDF contains an external URL action
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.
