MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF document contains embedded URLs that lead to potentially malicious content, masquerading as an "Infested salvage guide". The ML classifier strongly indicates maliciousness, and the presence of multiple external URIs suggests an attempt to redirect the user to a compromised or malicious site. While no scripts were explicitly extracted, the PDF structure and embedded URIs are indicative of a phishing or malware delivery attempt.

Heuristics 3

  • 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.
