The PDF file contains an embedded XFA form with a payload that exploits CVE-2010-0188 in Adobe Reader. This indicates the document is designed to deliver a malicious payload upon opening in a vulnerable application. The ClamAV detection 'Pdf.Exploit.Dropped-90' further confirms its malicious nature.

ClamAV: Pdf.Exploit.Dropped-90 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Dropped-90
ASCIIHexDecode filter (with exploit indicators) medium PDF_FILTER_HEX

Hex-encoding filter present alongside exploit delivery indicators — often used to hide payload or shellcode bytes
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
PDF differential parser failed info PDF_DIFFERENTIAL_PARSE_FAILED

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