MITRE ATT&CK

T1203 Exploitation for Client Execution T1059 Command and Scripting Interpreter

The sample is a PDF document that exploits the CVE-2010-0188 vulnerability in Adobe Reader. This vulnerability allows for the execution of arbitrary code, which is a common technique for delivering secondary payloads. The embedded file and XFA form indicate the presence of exploit code within the PDF structure. No specific family could be identified, but the exploit vector is clear.

Heuristics 4

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.
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
PDF differential parser failed info PDF_DIFFERENTIAL_PARSE_FAILED

The cross-check parser (pdfminer.six) failed on this file: PDF differential parser failed: PSEOF. Static heuristics still ran and any of their findings above are valid; only the differential cross-check signal is missing.
