MITRE ATT&CK

T1203 Exploitation for Client Execution

The sample is a PDF file that exploits the CVE-2010-0188 vulnerability in Adobe Reader. This vulnerability allows for arbitrary code execution when a user opens a specially crafted PDF file. The exploit is delivered via an XFA form and a LibTIFF payload embedded within the PDF.

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.
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
