MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.001 PowerShell

The critical heuristic firing indicates exploitation of CVE-2010-0188, a known vulnerability in Adobe Reader related to LibTIFF XFA image handling. This suggests the PDF is designed to achieve arbitrary code execution upon opening. While no specific scripts were extracted, the embedded nature of the exploit payload points towards a downloader or dropper functionality. The lack of readable document body text and the nature of the exploit itself prevent further specific attribution.

Heuristics 4

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.
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.
