MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF file is image-only, a common tactic for phishing lures. It contains a clickable link disguised as an image, directing users to a URL shortener. The embedded text suggests a prize lure, further indicating a phishing attempt.

Heuristics 3

Image-only PDF lure links through URL shortener high PDF_IMAGE_LURE_SHORTENER_LINK

PDF is image-heavy with little real text and its clickable action points to a URL shortener. This is a high-confidence credential-phishing carrier shape: the visible page is a screenshot-like prompt while the destination is hidden behind redirect infrastructure.
Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE

PDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 19 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
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.
