MITRE ATT&CK

T1566.001 Spearphishing Attachment T1027 Obfuscated Files or Information

The PDF file exhibits characteristics of malicious intent, including obfuscated objects and an embedded file, as flagged by ClamAV. The presence of an embedded file suggests it may be used to deliver a secondary payload or exploit. The document body itself is heavily obfuscated and unreadable, further supporting the idea that the primary purpose is not legitimate content delivery.
