T1204.002 Malicious Link
The PDF contains a critical heuristic firing for a malicious redirector link, specifically `https://ttraff.ru/pify?keyword=credit+scorecard+pdf`. This URL is part of a link farm designed to host numerous SEO-optimized PDF files, likely as a lure. The ML classifier also strongly flagged this PDF as malicious. The document body contains garbled text but includes the primary malicious URL and several benign-looking Shopify URLs, suggesting a social engineering attempt to redirect users to malicious infrastructure.
