MITRE ATT&CK

T1204 Malicious Link T1204.002 Malicious File T1059 Command and Scripting Interpreter T1059.001 PowerShell

The PDF file contains embedded XFA (XML Forms Architecture) data which is known to be vulnerable to CVE-2010-0188. Heuristics indicate an embedded script payload designed to exploit this vulnerability. The script itself is heavily obfuscated but appears to be designed to download and execute a second-stage payload, likely leveraging the embedded URL for this purpose.
