MITRE ATT&CK

T1204.002 Malicious File T1566.001 Spearphishing Attachment

The sample is a PDF document that exploits CVE-2010-0188, a known vulnerability in Adobe Reader related to XFA forms and TIFF image parsing. The critical heuristic firing confirms this exploit is present and likely attempts to execute embedded code. The embedded file, 'embedded_file_obj0001.bin', is highly suspicious and probably contains the secondary payload. The document body is heavily obfuscated and unreadable, providing no further context on the lure.

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
