T1204.002 Malicious File
T1559.001 Component Object Model Hijacking
The PDF file contains an XFA form and triggers the CVE-2010-0188 heuristic, indicating it exploits a vulnerability in Adobe Reader related to LibTIFF and XFA images. The exploit likely delivers a second-stage payload embedded within the decompressed stream. The use of ASCIIHexDecode and ASCII85Decode filters further supports the presence of obfuscated malicious content.
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
