MITRE ATT&CK

T1203 Exploitation for Client Execution

The PDF file contains embedded JavaScript and an XFA form, which are leveraged by the CVE-2010-0188 exploit targeting Adobe Reader. This exploit is designed to download and execute a secondary payload, as indicated by the critical heuristic firing for this CVE and the presence of an embedded file artifact. The embedded JavaScript and the nature of the exploit strongly suggest an attempt to gain initial access and execute further malicious code.
