MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF was flagged by ML classifiers and ClamAV as malicious, specifically as a dropper. Embedded JavaScript actions and streams indicate the presence of executable code within the PDF. While the JavaScript content itself was not detailed, its presence strongly suggests an attempt to download and execute a secondary payload, a common dropper behavior. The 'test' in the document body is likely a placeholder and does not provide further context.
