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

The PDF document contains a large number of external links, a technique often used for SEO poisoning or to redirect users to malicious sites. The document body suggests a lure related to "Cpm course 2 answers", indicating a potential phishing or scam attempt. The embedded links point to various domains, many of which are likely part of a link farm designed to obscure the true destination or spread malicious content.
