T1566.001 Spearphishing Attachment

The PDF file contains an embedded URI that redirects to a suspicious URL, identified by ClamAV as Pdf.Phishing.Trojan. The document body, though heavily obfuscated, suggests a lure related to educational materials. The presence of an external URI and the ClamAV detection strongly indicate a phishing or malware distribution attempt.
