MITRE ATT&CK

T1059.001 PowerShell

The PDF was flagged by multiple heuristics, including a critical ClamAV detection for 'Pdf.Exploit.Agent-36014'. ML classification also strongly indicated maliciousness. Embedded JavaScript was detected and further analysis revealed obfuscation techniques, suggesting it's used to download and execute a second-stage payload. The document body contained no readable text, but the presence of JavaScript and the exploit detection point to a typical exploit-delivery PDF.
