MITRE ATT&CK

T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The PDF is identified as a malicious redirector link, likely a phishing lure. The heuristic 'PDF_IMAGE_LURE' indicates it's an image-only document designed to trick users into clicking a link. The primary IOC is the malicious URL found within the document, which is confirmed by multiple heuristics and ClamAV detection.

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 42 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.
