MITRE ATT&CK

T1566.001 Spearphishing Attachment T1027 Obfuscated Files or Information

The PDF file exhibits characteristics of malicious intent, including obfuscated object names and an embedded file, as detected by ClamAV. The presence of an embedded file suggests the document is a container for delivering additional malicious content. The document body itself is heavily garbled, further supporting the obfuscation finding.
