MITRE ATT&CK
T1203 Exploitation for Client Execution

The file is a PDF document that contains an embedded XFA form with a payload matching the CVE-2010-0188 exploit. This exploit targets a vulnerability in Adobe Reader's handling of TIFF images within XFA forms, leading to arbitrary code execution. The embedded file 'embedded_file_obj0001.bin' is likely the second-stage payload.

Heuristics 4

  • Adobe Reader LibTIFF XFA image exploit — CVE-2010-0188 critical CVE likely CVE_2010_0188
