T1203 Exploitation for Client Execution
The PDF contains a large number of external links, many of which are structured as SEO-friendly URLs pointing to game-related content, suggesting a link farm or phishing lure. The ML classifier also flagged this PDF as malicious with high confidence. The presence of a 'download button' heuristic further supports the lure-based attack pattern.
