MITRE ATT&CK
T1203 Exploitation for Client Execution

The sample is a PDF document that triggers the CVE-2010-0188 exploit, targeting a vulnerability in Adobe Reader's handling of XFA forms. The embedded XFA payload is decoded and executed, leading to the download of a secondary payload. The ClamAV detection further confirms its malicious nature. The embedded URL is likely part of the exploit chain.
