MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF is identified as malicious by an ML classifier and exhibits characteristics of a phishing lure, specifically an image-only document designed to trick users into clicking a link. The embedded URI points directly to an IP address, which is a common tactic for evading domain-based detection. No scripts were extracted, but the PDF structure itself indicates a malicious intent to redirect the user to a potentially harmful resource.

Heuristics 3

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 26 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
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.
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.
