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

This PDF file was flagged by a machine learning classifier and ClamAV as malicious, indicating a phishing or trojan threat. It contains an embedded URI pointing to 'traffine.ru', likely a malicious domain used for further exploitation. The document body, though heavily obfuscated, contains references to 'Kennedy electronics' and the authoring application, suggesting a lure to a fake website. No scripts were extracted, but the presence of external URIs and the ML/ClamAV detections strongly suggest a malicious intent.

  • 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.
