MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains an embedded URI pointing to a suspicious domain, identified as malicious by ClamAV and an ML classifier. The document body, though heavily obfuscated, suggests a lure related to a textbook download, which is a common phishing tactic. The presence of an external URI indicates an attempt to redirect the user to a potentially harmful site.
