MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of external links to other PDF files, masquerading as educational material for 'Plant Kingdom Class 11 Notes'. This is indicative of a link farm used for phishing or malware distribution. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or traffic redirection intent. The embedded URLs are the primary IOCs, likely leading to malicious payloads.
