MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.001 PowerShell

The PDF file contains embedded JavaScript and an embedded file, and a critical heuristic firing indicates exploitation of CVE-2010-0188 via an XFA image. This vulnerability allows for arbitrary code execution. The embedded JavaScript and file suggest a downloader or dropper functionality, aiming to fetch and execute additional malicious content. The confidence is moderate due to the lack of specific script content to confirm the exact payload.
