T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The PDF document contains numerous links to external websites, many of which are SEO-optimized PDFs designed to appear as hack tools or generators for games like Coin Master and Roblox. The ML classifier strongly indicated maliciousness, and the presence of a "download button" heuristic further supports a lure-based attack. The primary goal appears to be directing users to download potentially unwanted or malicious applications from the linked URLs.
