MITRE ATT&CK
T1059.003 Windows Command Shell
T1204.002 Malicious File
The PDF file contains a launch action that executes cmd.exe. This command interpreter is then used to download a file from 'http://iamjuza.googlecode.com/files/dropper.txt' and likely execute it. The embedded script uses 'Scripting.FileSystemObject' and 'WinHttp.WinHttpRequest.5.1' to facilitate this download and execution process, indicating a downloader or droppper functionality.
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.
-
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://iamjuza.googlecode.com/files/dropper.txt
