MITRE ATT&CK
T1204.002 Malicious File: Malicious File

The PDF file contains embedded JavaScript and utilizes ASCIIHexDecode filters, strongly indicating an exploit attempt. ClamAV detections of 'Pdf.Exploit.Agent-36175' confirm its malicious nature. The embedded JavaScript is likely responsible for downloading and executing a secondary payload, a common technique for initial access.

Heuristics 5

  • ClamAV: Pdf.Exploit.Agent-36175 critical CLAMAV_DETECTION
