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

The PDF file contains a heuristic indicating an external URI, specifically 'https://jacksth.ru/wix?keyword=acura+ilx+owners+manual'. This URL is presented in a context that suggests a phishing attempt, masquerading as a vehicle owner's manual. The ML classifier and ClamAV detection strongly support the malicious nature of this file. No scripts were extracted, but the presence of the malicious URL is sufficient to infer a phishing attack pattern.

  • 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.
