MITRE ATT&CK

T1566.001 Spearphishing Attachment T1027 Obfuscated Files or Information

The PDF file exhibits characteristics of malicious intent, including obfuscated content and an embedded file, as flagged by ClamAV and static triage. The presence of an embedded file suggests it may be used to deliver a secondary payload. The document body itself is unreadable, further supporting the obfuscation finding.
