MITRE ATT&CK
T1059.003 Windows Command Shell
T1204.002 Malicious File
The PDF file contains an embedded script that is configured to launch cmd.exe. This indicates an attempt to execute arbitrary commands on the user's system. The embedded script itself is likely responsible for the malicious payload delivery, as suggested by the 'PDF_EMBEDDED_SCRIPT_PAYLOAD' heuristic.
Heuristics 4
-
Launch action critical PDF_LAUNCHPDF 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_COMMANDPDF /Launch action specifies an executable target — references a known-dangerous executable (cmd, PowerShell, etc.).
-
Embedded script payload in PDF stream high PDF_EMBEDDED_SCRIPT_PAYLOADPDF 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.
-
