MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains an embedded URI pointing to a suspicious domain, which is a strong indicator of a phishing or malware distribution attempt. ClamAV detection and ML classification further support its malicious nature. The document body, though heavily obfuscated, contains strings related to software and device names, likely part of a lure.
