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 the primary mechanism for delivering the malicious payload, likely involving downloading and executing a second-stage artifact. The document body is unreadable, so the rationale is based on the technical findings.

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.
