T1566.001 Spearphishing Attachment
The PDF contains a link farm with numerous URLs pointing to game-related cheats and hacks, and a primary external URI to 'netcdn.tw'. The heuristic 'PDF_SEO_LINK_FARM' indicates a large number of external links, suggesting a tactic to distribute malicious content or engage in SEO manipulation. The ML classifier strongly flagged this PDF as malicious, and the presence of a 'download button' lure reinforces the malicious intent.
