MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.004 Command and Scripting Interpreter: PowerShell

The PDF file contains an XFA form and triggers a critical heuristic for CVE-2010-0188, indicating exploitation of a vulnerability in Adobe Reader related to LibTIFF and XFA images. The presence of ASCIIHexDecode and ASCII85Decode filters further supports the exploitation attempt. The extracted artifact 'stream_000_off00000207.bin' likely contains the exploit payload. No scripts were extracted, and the document body was unreadable, but the exploit itself is the primary indicator of malicious intent.

Heuristics 5

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.
ASCIIHexDecode filter (with exploit indicators) medium PDF_FILTER_HEX

Hex-encoding filter present alongside exploit delivery indicators — often used to hide payload or shellcode bytes
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
