MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a large number of embedded URLs pointing to other PDF files, a technique often used for SEO spam or to distribute malicious content. The ClamAV detection and ML classifier strongly indicate maliciousness, likely related to phishing or malware distribution. No scripts were extracted, and the document body content is heavily corrupted, preventing a more detailed analysis of the specific lure.
