T1203 Exploitation for Client Execution
T1027 Obfuscated Files or Information
The PDF file contains an embedded XFA form and triggers the CVE-2010-0188 exploit, indicating it's designed to execute arbitrary code upon opening in a vulnerable Adobe Reader version. The presence of ASCIIHexDecode and ASCII85Decode filters further suggests obfuscation of the malicious payload within the document stream. The extracted artifact 'stream_000_off000001f9.bin' likely contains the secondary payload.
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
-
