MITRE ATT&CK

T1204.002 Malicious File: User Execution: Malicious File

The file is identified as a malicious PDF by multiple high-confidence heuristics, including ML classification and ClamAV detections. The presence of embedded JavaScript, indicated by PDF_JAVASCRIPT and PDF_JS heuristics, suggests an attempt to execute malicious code upon opening the document. This likely leads to the exploitation of a PDF vulnerability to achieve arbitrary code execution.

ClamAV: Pdf.Exploit.Agent-36365 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-36365
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.
