T1566.001 Spearphishing Attachment

The PDF file contains an embedded URI pointing to a suspicious domain, which is likely part of a phishing or malware distribution scheme. ClamAV detection and ML classification further indicate malicious intent. The document body, though heavily obfuscated, appears to be a lure for movie downloads, a common tactic for phishing and malware distribution.
