MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. ClamAV detections (Win.Trojan.Agent-36166) confirm its malicious nature. The embedded JavaScript is likely responsible for downloading and executing a second-stage payload, contributing to the overall attack pattern of malware delivery. The large size of the JavaScript stream suggests complex malicious functionality.

Heuristics 4

ClamAV: Win.Trojan.Agent-36166 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Win.Trojan.Agent-36166
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV
