MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file was identified as malicious by a ClamAV signature and an ML classifier, indicating a high likelihood of malicious intent. The PDF contains an embedded URI that points to a URL, likely intended to redirect the user to a phishing or malware distribution site. While no scripts were explicitly extracted, the PDF structure and the presence of embedded URIs suggest an attempt to exploit users through social engineering.

  • 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.
