MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains an embedded URI pointing to a suspicious domain, which is also flagged by ClamAV as a phishing trojan. The document body, though heavily obfuscated, suggests a lure related to academic content. The presence of an external URI and the ClamAV detection strongly indicate a phishing or malware distribution attempt.
