MITRE ATT&CK

T1059.001 PowerShell

The PDF contains embedded JavaScript, flagged by multiple heuristics including PDF_JAVASCRIPT and PDF_JS. The presence of an eval() call within the JavaScript stream (PDF_EVAL) strongly suggests code execution. The ML classifier and ClamAV detection further confirm its malicious nature, identifying it as Pdf.Dropper.Agent-7246737-0. The script is likely responsible for downloading and executing a second-stage payload, a common dropper behavior.
