T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The PDF contains numerous embedded links, including invisible ones, that lead to CAPTCHA-themed lures and potentially malicious sites. The document body and extracted URLs suggest a scam related to free in-game currency or hacks, aiming to trick users into completing verification steps that likely involve credential harvesting or malware download. The ML classifier strongly indicated maliciousness, and the presence of external URIs and CAPTCHA lures supports a phishing or social engineering attack pattern.

Heuristics 4
-
Invisible PDF links to CAPTCHA-themed web lure high PDF_CAPTCHA_LINK_LUREPDF contains invisible clickable link annotations that point to a CAPTCHA/capcha-themed web path. This is a common phishing and ClickFix-style routing pattern: the PDF itself is inert, while the linked page performs the credential prompt or fake verification.
-
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 http://netcdn.tw/app/431946152/free-robux-without-verification-or-survey-game-hack
