MITRE ATT&CK

T1555 Credentials from Password Stores T1059 Command and Scripting Interpreter

The PDF file was flagged by ClamAV for having an obfuscated object name, a common technique for hiding malicious content. Static triage also identified a suspicious embedded file. The document body is heavily obfuscated and unreadable, suggesting it is not intended for human consumption but rather to exploit vulnerabilities or deliver a secondary payload via the embedded artifact.
