T1566.002 Phishing: Spearphishing Attachment
T1204.002 Malicious Link
The PDF file utilizes an image-only lure, a common phishing tactic to trick users into interacting with a hidden clickable element. The heuristic 'PDF_ESCAPED_URI_IMAGE_LURE' specifically identifies a malicious URL embedded within the PDF, which is likely intended to redirect the user to a compromised site for further exploitation. The ML classifier also strongly indicates malicious intent.

-
Image-heavy PDF hides clickable URL with PDF string escapes high PDF_ESCAPED_URI_IMAGE_LUREPDF is image-heavy with little real text and its clickable HTTP(S) URI is encoded with PDF octal escapes. This combination is common in credential-phishing PDFs that render a screenshot-like prompt and obscure the destination from simple URL extractors.
-
Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LUREPDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 200 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
