T1566.001 Spearphishing Attachment

The PDF is identified as a phishing lure due to its structure, containing an image overlay and an embedded URI. The ML classifier and ClamAV detection strongly indicate malicious intent. Although the embedded URL is marked as benign, the overall pattern suggests the document is designed to redirect users to a malicious site, likely for phishing or malware distribution.
