MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The critical ClamAV heuristic indicates the file is a known malicious PDF exploit (Pdf.Exploit.Agent-36066). Low-severity heuristics confirm the presence of JavaScript actions and embedded JS streams within the PDF structure. The JavaScript is likely responsible for the malicious behavior, such as downloading and executing a secondary payload, which is a common attack pattern for such documents. The document body content was unreadable, preventing a more specific analysis of the lure.
