T1204.002 Malicious File
T1566.002 Spearphishing Attachment
The file is identified as malicious by ML classification and ClamAV with the signature 'Pdf.Exploit.Agent-36874'. Static analysis revealed it is a PDF with XFA form elements and an AcroForm button with an action trigger, common characteristics of exploit-laden PDFs. An embedded, decompressed PDF stream was also found, suggesting a multi-stage exploit. The exact exploit mechanism is not detailed, but the presence of these elements strongly indicates an attempt to leverage a PDF vulnerability.
