MITRE ATT&CK

T1203 Exploitation for Client Execution

The sample is a PDF document that leverages an embedded XFA form to exploit the CVE-2010-0188 vulnerability in Adobe Reader. This vulnerability allows for the execution of arbitrary code, likely to download and run a secondary payload. The PDF structure and the specific exploit identified strongly indicate a malicious intent to compromise the user's system.
