MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

This PDF file contains embedded JavaScript that attempts to launch an executable named 'ADMPlugin.apl' from the user's profile directory. The PDF also contains a launch action that executes a command to change directory and then attempt to execute the 'ADMPlugin.apl' file if it exists. The presence of JavaScript and a launch action strongly suggests an attempt to execute a malicious payload.
