MITRE ATT&CK

T1553.004 Subvert Trust Controls: Mark-of-the-Web Bypass

The PDF file exhibits suspicious characteristics, including an embedded file and a critical ClamAV detection for obfuscated name objects. The presence of an embedded file suggests it's a dropper or container for a secondary malicious artifact. The document body content is heavily obfuscated and unreadable, further supporting the malicious nature.
