MITRE ATT&CK

T1059.001 PowerShell T1059.007 JavaScript

The PDF file contains embedded JavaScript with multiple obfuscation indicators and a high-confidence `eval()` call. This JavaScript is likely responsible for downloading and executing a second-stage payload, as suggested by the ClamAV detection name 'Pdf.Dropper.Agent-7284881-0'. The presence of PDF-specific JavaScript heuristics further supports this attack pattern.
