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. The presence of an embedded file suggests it is likely intended to be extracted and executed, serving as a delivery mechanism for further malicious activity. The document body itself is heavily obfuscated and unreadable, further supporting the conclusion that the file's primary purpose is malicious.
