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 the malicious nature of the file. The embedded JavaScript is likely responsible for executing the malicious payload, as suggested by the ClamAV detection on an extracted artifact. The exact functionality of the script is not fully discernible due to potential obfuscation, but its presence is a strong indicator of malicious intent.

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.
