MITRE ATT&CK
T1059.001 PowerShell
T1204.002 Malicious File
The PDF file contains embedded JavaScript with multiple eval() calls, indicating obfuscation and malicious intent. The ClamAV detection 'Pdf.Exploit.Agent-36118' strongly suggests exploitation of a known PDF vulnerability. The JavaScript is heavily obfuscated, but the presence of eval() and string concatenation points towards dynamic code execution, likely for downloading and executing a secondary payload. The authoring application 'Scribus 1.3.3.12' is not inherently suspicious but provides context for the file's origin.
