MITRE ATT&CK

T1059.003 Windows Command Shell T1204.002 Malicious File

The PDF file contains a launch action that executes cmd.exe, which in turn is instructed to download and execute a file from the URL http://www.directvirus.com/sw3243223.exe. This indicates a downloader or droppper functionality. The embedded script payload and the launch action targeting cmd.exe are strong indicators of malicious intent.

Heuristics 5

/Launch action target: "cmd.exe" critical PDF_LAUNCH_COMMAND

PDF /Launch action specifies an executable target — references a known-dangerous executable (cmd, PowerShell, etc.).
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.
Suspicious extracted artifact medium EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
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://www.directvirus.com/sw3243223.exe
