MITRE ATT&CK

T1203 Exploitation for Client Execution

The PDF file contains an XFA form and utilizes ASCII85Decode filters, which are indicators of malicious intent. Specifically, the 'CVE_2010_0188' heuristic firing confirms the exploitation of a known Adobe Reader vulnerability (CVE-2010-0188) via an embedded XFA image/tif payload. This indicates the primary attack pattern is likely to achieve arbitrary code execution on the victim's system.

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
