MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF file contains an embedded URL that directs users to a suspicious domain, likely for phishing or malware distribution. The document body, though heavily obfuscated, contains text related to the Bhagavad Gita, suggesting a lure to entice users to click the malicious link. The presence of an external URI and ML classification strongly indicate malicious intent.
