MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.001 PowerShell

The PDF file contains an embedded XFA form and triggers the CVE-2010-0188 exploit, indicating it's designed to execute arbitrary code upon opening in a vulnerable Adobe Reader version. The embedded artifact 'embedded_file_obj0008.bin' likely contains the secondary payload. The ClamAV detection confirms the exploit's presence. No scripts were directly extracted, but the exploit itself is the primary indicator of malicious intent.

Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
