This PDF file was flagged as malicious by ClamAV and a machine learning classifier, indicating it contains an exploit. The presence of an embedded script payload and XFA form suggests the file is designed to leverage PDF vulnerabilities for code execution. The embedded script is likely responsible for downloading and executing a second-stage payload, though its exact functionality is obscured.
