MITRE ATT&CK
T1204 Malicious Link T1204.002 Malicious Link: Submitted Malware T1059 Command and Scripting Interpreter T1059.003 Command and Scripting Interpreter: Windows Command Shell

The PDF file contains a launch action that executes cmd.exe, indicating an attempt to run arbitrary commands. The embedded URL 'http://127.0.0.1/calc1.jpg' likely points to a secondary payload. The PDF_LAUNCH_COMMAND heuristic firing confirms the execution of cmd.exe, and the PDF_EMBEDDED_SCRIPT_PAYLOAD suggests the presence of malicious script content within the PDF stream.

Heuristics 4

  • /Launch action target: "cmd.exe" critical PDF_LAUNCH_COMMAND
    PDF /Launch action specifies an executable target — references a known-dangerous executable (cmd, PowerShell, etc.).
  • Launch action high PDF_LAUNCH
    PDF contains a /Launch action with an unresolved or extension-less target — treat as potentially dangerous
  • 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.
  • 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.
    URL http://127.0.0.1/calc1.jpg
