T1566.001 Spearphishing Attachment

This PDF file was flagged by ClamAV as a phishing trojan and by an ML classifier, indicating malicious intent. It contains embedded URLs, suggesting it may be used to lure users to malicious sites or download further payloads. The presence of PDF-specific heuristics and embedded font streams further supports its nature as a potentially malicious document.

  • 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.
