MITRE ATT&CK
T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The PDF file contains an embedded XFA form that exploits CVE-2010-0188, a vulnerability in Adobe Reader's LibTIFF component. This exploit allows for the execution of arbitrary code upon opening the document, likely leading to the download and execution of a secondary payload. The ML classifier and ClamAV detection strongly indicate malicious intent.
