MITRE ATT&CK
T1203 Exploitation for Client Execution T1059.007 JavaScript

The PDF file contains a launch action that exploits CVE-2010-1240 to execute cmd.exe. The embedded JavaScript object 'javascript_obj0110_000.js' contains a call to 'this.t({ cName: "ADMPlugin", nLaunch: 0 });', which likely triggers the execution of the embedded 'ADMPlugin.apl' file. This chain of execution suggests the PDF is designed to download and run a second-stage payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9985

Heuristics 7

  • Adobe Reader Launch action command execution critical CVE exact CVE_2010_1240
    PDF uses the Adobe Reader/Acrobat Launch action pattern associated with CVE-2010-1240: cmd.exe is invoked with attacker-controlled parameters, paired with an embedded/exported payload.
  • ClamAV: Pdf.Tool.Agent-1388586 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Tool.Agent-1388586
  • Launch action critical PDF_LAUNCH
    PDF 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_COMMAND
    PDF /Launch action specifies an executable target with parameters '/Q /C %HOMEDRIVE%&cd %HOMEPATH%&(if exist "%USERPROFILE%\\����\\ADMPlugin.apl" (cd/D "%USERPROFILE%\\����"' — references a known-dangerous executable (cmd, PowerShell, etc.).
  • PDF embedded file could not be fully decoded medium PDF_EMBEDDED_FILE_UNDECODED
    A declared PDF /EmbeddedFile stream uses filters that the scanner could not decode. The raw stream was carved for artifact triage because malformed or unsupported attachment filters can hide payload content from normal extraction.
  • Embedded file low PDF_EMBEDDED
    PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
  • 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.
