MITRE ATT&CK

T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF file contains a URL that is likely part of a phishing or malicious content delivery scheme. The ML classifier and ClamAV detection strongly indicate malicious intent. Although no scripts were directly extracted, the PDF structure and embedded URI suggest it's designed to redirect users to a potentially harmful external resource.

External URI info PDF_URI

PDF contains an external URL action
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL

The same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
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.
