MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF file contains a large number of embedded links to other PDF documents, a technique often used for SEO poisoning or to distribute further malicious content. The heuristic 'PDF_SEO_LINK_FARM' and ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' strongly indicate malicious intent. The document body, though heavily obfuscated, suggests a lure to enable editing, which is a common tactic for macro-based malware delivery.
