T1204.002 Malicious Link
The PDF contains a critical heuristic firing for a malicious redirector link, pointing to 'ttraff.com'. This URL is presented within the document body, disguised as a 'bank po syllabus 2020 pdf', indicating a phishing or social engineering lure. The presence of a large number of external PDF links, many hosted on Shopify, suggests a link farm or SEO poisoning tactic to distribute malicious content. The ML classifier also strongly flagged this PDF as malicious.
