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 MITRE ATT&CK techniques T1059.001 (PowerShell) and T1204.002 (Malicious File). The document body is unreadable, but the presence of JavaScript and the ClamAV detection strongly suggest a malicious intent, possibly to download and execute further malware.
