MITRE ATT&CK

T1204.002 Malicious File T1059.001 PowerShell T1204 User Execution

The sample is a PDF file that contains an XFA form and triggers the CVE-2010-0188 exploit. This exploit targets a vulnerability in Adobe Reader related to LibTIFF and XFA images, allowing for arbitrary code execution. The presence of ASCIIHexDecode and ASCII85Decode filters further indicates obfuscation commonly used in exploit delivery. The primary attack vector is likely the exploitation of this vulnerability to download and execute a secondary payload.

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
