MITRE ATT&CK
T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The PDF sample was flagged by multiple heuristics, including a critical ClamAV detection for 'Pdf.Exploit.Agent-34360' and a high severity heuristic for a dangerous URI referencing a command interpreter. This indicates the file is designed to exploit a vulnerability within the PDF reader to achieve code execution. The presence of a command interpreter path in a URI strongly suggests the exploitation of a known PDF vulnerability for arbitrary code execution, likely to download and execute a secondary payload.

  • PDF URI references command interpreter path high PDF_DANGEROUS_URI_COMMAND
    PDF contains a malformed /URI action whose target uses a mailto/path traversal shape and references a command interpreter or scripting host. This is not a normal web link and matches legacy PDF command execution/dropper lures.
  • 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.
