MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.001 PowerShell

The PDF file contains a critical heuristic match for CVE-2010-0188, an Adobe Reader LibTIFF XFA exploit. This indicates the file is designed to exploit this vulnerability for client-side code execution. The presence of XFA forms and ASCIIHexDecode/ASCII85Decode filters further supports this attack vector. The exploit likely leads to the download and execution of a secondary payload, though no specific details of the payload were extracted.

Heuristics 5

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.

Hex-encoding filter present alongside exploit delivery indicators — often used to hide payload or shellcode bytes
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
ASCII85Decode filter (with exploit indicators) low PDF_FILTER_85

ASCII85 encoding filter present alongside exploit delivery indicators — uncommon outside of obfuscation
