MITRE ATT&CK

T1204 Malicious Link T1204.002 Malicious File

The file is identified as a malicious PDF by ClamAV with the signature Pdf.Exploit.Agent-36874. Static analysis indicates the presence of XFA forms and AcroForm buttons with action triggers, commonly used in PDF exploits. The extracted document body content is heavily obfuscated and does not provide clear user-facing text, suggesting the primary purpose is exploit delivery rather than social engineering through readable content. The file's structure and heuristic firings strongly suggest it leverages a PDF vulnerability to achieve code execution.
