MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, many of which are related to game hacks and cheats for popular games like Free Fire, Coin Master, Minecraft, and Roblox. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs suggests an attempt to redirect users to download potentially harmful content or visit phishing sites. No scripts were extracted from this sample, but the overall pattern indicates a lure for unwanted software or phishing.
