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

The PDF document contains embedded text and a URL that mimics a vehicle owner's manual, likely as a lure. The ML classifier strongly flagged this PDF as malicious, and an external URI was detected pointing to 'https://trafffi.ru/123?keyword=owners+manual+for+2017+nissan+frontier+sv'. No scripts were extracted, but the presence of the malicious URL suggests an attempt to redirect the user to a potentially harmful site.

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.
