T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The sample is a PDF file identified as malicious by ClamAV (Pdf.Exploit.Agent-36821). Static analysis detected the use of XFA forms and specifically the CVE-2010-0188 exploit targeting Adobe Reader. The embedded URL, while seemingly benign, is part of the XFA template structure and likely used in the exploit chain. The document body contains obfuscated JavaScript-like code, further indicating malicious intent.
