T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document contains numerous links to external websites, many of which are related to free in-game currency or cheats for popular games like Roblox and Coin Master. The heuristic 'PDF_SEO_LINK_FARM' indicates a large number of such links, suggesting a tactic to drive traffic to potentially malicious sites. The ML classifier also strongly flagged this PDF as malicious. The presence of a 'download button' lure further supports the intent to trick users into clicking these links, which likely lead to phishing pages or malware downloads.
