MITRE ATT&CK

T1059.001 PowerShell

The file is a PDF containing embedded JavaScript, as 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, a common technique for this type of threat. The presence of JavaScript actions and streams points towards T1059.001 (PowerShell) or T1059.005 (Visual Basic) as the execution method.

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

ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
JavaScript action low PDF_JAVASCRIPT

PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded JS stream low PDF_JS

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
