MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious Link

The PDF file contains multiple embedded URLs that point to other PDF files hosted on the same domain. The presence of a polyglot child PDF with suspicious static findings suggests that these embedded files are likely malicious. The primary attack pattern involves luring the user to click on these links, which would then lead to the download and potential execution of further malware. No scripts were extracted from this sample, limiting the ability to determine specific execution methods.

Heuristics 4

  • Secondary embedded PDF body has suspicious static findings high POLYGLOT_CHILD_PDF_STATIC_TRIAGE
    A valid PDF body was found at a nonzero offset inside another container and its carved contents matched PDF exploit or lure heuristics. This catches polyglots where the top-level magic routes to ZIP/OLE while a PDF reader or downstream parser opens the hidden PDF payload.
  • 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.
