MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The critical ClamAV heuristic indicates this PDF is recognized as malware (Pdf.Exploit.Agent-36142). Low-severity heuristics for PDF JavaScript actions and embedded JS streams confirm the presence of executable code within the document. The embedded JavaScript is likely responsible for exploiting a vulnerability to achieve arbitrary code execution, aligning with the T1204.002 (Malicious File) and T1059.001 (PowerShell, as JavaScript can be used to invoke it) MITRE ATT&CK techniques. The document body was unreadable, but the heuristics and detection name strongly suggest a malicious exploit.
