T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a large number of embedded URLs pointing to external PDF files, a technique commonly used for SEO poisoning or phishing. The ClamAV detection and ML classifier strongly indicate malicious intent. The document body, though partially corrupted, suggests a lure related to an 'Angles of elevation and depression worksheet', which is likely a pretext to disguise the malicious links.
