MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF contains embedded links and a call-to-action phrase, directing users to download files from external URLs. The ML classifier strongly indicated maliciousness, and the presence of multiple links to potentially malicious content suggests a phishing or malware distribution attempt. No scripts were extracted, but the document's structure and embedded URIs are indicative of a lure for downloading further malicious content.

Heuristics 4

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.
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

Document 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_URI

PDF contains an external URL action
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.
