T1059.004 Command and Scripting Interpreter: PowerShell
The PDF file contains an XFA form and triggers the CVE-2010-0188 heuristic, indicating exploitation of a LibTIFF vulnerability within Adobe Reader. The exploit is embedded within an XFA image and delivered via ASCIIHexDecode and ASCII85Decode filters. The primary attack vector is the exploitation of this known vulnerability to achieve code execution.
Heuristics 5
-
Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188PDF 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.
-
ASCIIHexDecode filter (with exploit indicators) medium PDF_FILTER_HEXHex-encoding filter present alongside exploit delivery indicators — often used to hide payload or shellcode bytes
-
XFA form low PDF_XFAPDF uses XML Forms Architecture — can contain script logic
-
ASCII85Decode filter (with exploit indicators) low PDF_FILTER_85ASCII85 encoding filter present alongside exploit delivery indicators — uncommon outside of obfuscation
