MITRE ATT&CK

T1204.002 Malicious File T1566.001 Spearphishing Attachment

The PDF file contains an embedded exploit targeting CVE-2010-0188 in Adobe Reader, as indicated by critical heuristic firings. This exploit is designed to execute arbitrary code, likely leading to the download and execution of a second-stage payload. The presence of an embedded file further supports the malicious intent.

Heuristics 7

Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188

PDF contains XFA image data with an inline crafted TIFF payload and shellcode/delivery markers. This is the data-bound variant of the CVE-2010-0188 Adobe Reader LibTIFF/XFA exploit shape.
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.
