The PDF contains an embedded URI and multiple other URLs that appear to be lures for downloading game hacks or cheats. The ML classifier also flagged this PDF as malicious. The document body, though heavily obfuscated, contains references to a "free booster game hack" for TikTok, suggesting a social engineering attempt to trick users into downloading a payload.
