T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a prominent link that redirects to a malicious URL, identified by the PDF_MALICIOUS_REDIRECTOR_LINK heuristic. The document body and heuristics suggest a lure related to exam answer keys, with a call-to-action button to encourage clicks. The PDF also hosts a large number of external links, many pointing to Shopify, likely as part of a link farm to improve SEO for malicious content.
