The PDF document contains embedded links that point to known malicious redirector infrastructure, specifically targeting users with lures for game-related downloads like Minecraft and Roblox. The presence of a visual download button and the ML classifier's high confidence score further support the malicious nature of this document. The embedded links likely serve to download and execute a second-stage payload.
