MITRE ATT&CK
T1203 Exploitation for Client Execution T1059.004 Command and Scripting Interpreter: PowerShell

The sample is a PDF file identified as malicious by ClamAV, specifically detecting it as Pdf.Exploit.Agent-36826. Static analysis revealed a critical heuristic match for CVE-2010-0188, an exploit targeting Adobe Reader's LibTIFF XFA image handling. The presence of an embedded URL, though benign in this case, is typical for exploit delivery. The XFA form structure is exploited to execute arbitrary code.
