The PDF contains an embedded URI pointing to a suspicious domain, likely intended to trick the user into downloading a malicious payload disguised as study material. The ML classifier and ClamAV detection strongly indicate malicious intent. While no scripts were explicitly extracted, the PDF structure and embedded URI suggest a phishing or malware distribution attempt.
