T1059.001 PowerShell
The sample is a PDF file identified as malicious by ClamAV (Js.Exploit.HTML-30) and an ML classifier. It contains XFA form elements and embedded JavaScript. The JavaScript appears to be obfuscated but is likely responsible for exploiting a PDF vulnerability to execute malicious code. The embedded URL is associated with XFA templates, suggesting a potential vector for exploit delivery.

PDF differential parser failed info PDF_DIFFERENTIAL_PARSE_FAILEDThe cross-check parser (pdfminer.six) failed on this file: PDF differential parser failed: PSEOF. Static heuristics still ran and any of their findings above are valid; only the differential cross-check signal is missing.
