MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a document body that explicitly advertises free game hacks and in-game currency for popular games like Roblox and Coin Master. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect users to download potentially harmful content. No scripts were extracted from this sample, but the overall lure is consistent with social engineering tactics to trick users into downloading malware.
