MITRE ATT&CK
T1204.002 Malicious File: User Execution: Malicious File T1059.003 Command and Scripting Interpreter: Windows Command Shell

The PDF contains a URI that attempts to exploit a command interpreter path, indicated by the 'PDF_DANGEROUS_URI_COMMAND' heuristic. This suggests an attempt to execute arbitrary commands, likely to download and run a secondary payload. The 'SE_LOLBIN_RUN_COMMAND' heuristic further supports the presence of command execution instructions within the document.

Heuristics 4

  • PDF URI references command interpreter path high PDF_DANGEROUS_URI_COMMAND
    PDF contains a /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.
  • Visible LOLBin command execution instruction high SE_LOLBIN_RUN_COMMAND
    Document contains instructions or visible command text involving Windows script/execution tools such as PowerShell, mshta, cmd, rundll32, or regsvr32
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
