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 Roblox and Coin Master. The ML classifier strongly flagged this PDF as malicious, and the presence of these links suggests an attempt to lure users to download potentially harmful files or visit phishing sites. No scripts were extracted, but the overall pattern indicates a social engineering lure, likely distributed as a spearphishing attachment.
