T1566.002 Spearphishing Attachment
T1204.002 Malicious File
The PDF file contains an embedded script payload and a launch action that targets cmd.exe. This indicates an attempt to execute arbitrary commands upon opening the document. The embedded script, named 'embedded_pdf_script_0003cc93.bin', is the likely mechanism for this execution. The document body provides no specific lure, but the technical indicators strongly suggest a malicious payload delivery.
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.
-
