MITRE ATT&CK
T1204.002 Malicious File T1059.003 Windows Command Shell

The PDF file contains an embedded script that triggers a launch action targeting cmd.exe. This indicates an attempt to execute arbitrary commands, likely to download and execute a second-stage payload. The heuristics strongly suggest a malicious PDF exploiting embedded scripts and launch actions.

Heuristics 4

  • Launch action critical PDF_LAUNCH
    PDF contains a /Launch action whose target is an executable, URL, or UNC path — can start an external application
  • /Launch action target: cmd.exe critical PDF_LAUNCH_COMMAND
    PDF /Launch action specifies an executable target — references a known-dangerous executable (cmd, PowerShell, etc.).
  • Embedded script payload in PDF stream high PDF_EMBEDDED_SCRIPT_PAYLOAD
    PDF stream bytes contain script execution markers such as ActiveXObject/CreateObject, WScript.Shell, PowerShell, or shell-exec primitives. This is stronger than ordinary PDF JavaScript because it indicates a staged external script payload hidden in stream bytes.
  • Suspicious extracted artifact medium EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
