MITRE ATT&CK

The PDF file contains a large number of embedded URLs, indicating it functions as a link farm. The heuristic 'PDF_SEO_LINK_FARM' and ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' strongly suggest a phishing or malicious redirection scheme. The document body, despite being heavily obfuscated, mentions 'Indian constitution' and 'education', likely serving as a lure to attract victims to click on the numerous malicious links.
