MITRE ATT&CK

T1204.002 Malicious File T1059.001 PowerShell

The PDF file was flagged by ClamAV with a critical heuristic for obfuscated object names, indicating malicious intent. It also contains an embedded file, a common technique for delivering secondary payloads. The presence of XFA forms and embedded files suggests an attempt to exploit PDF vulnerabilities. The document body is heavily obfuscated and unreadable, further supporting a malicious interpretation.
