T1203 Exploitation for Client Execution
T1059.001 PowerShell
The sample is a PDF document that contains an embedded XFA form and an embedded file. Static analysis detected a critical heuristic indicating exploitation of CVE-2010-0188, a vulnerability in Adobe Reader related to LibTIFF XFA images. This suggests the document is designed to exploit this vulnerability to achieve code execution. The embedded file, 'embedded_file_obj0001.bin', is likely the secondary payload. No scripts were extracted, and the document body was heavily obfuscated, limiting further analysis of the immediate user-facing lure.
Heuristics 4
-
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.
-
Embedded file low PDF_EMBEDDEDPDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
-
XFA form low PDF_XFAPDF uses XML Forms Architecture — can contain script logic
-
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGEOne or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
