MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains links and a call-to-action button that directs users to download applications related to game cheats and hacks. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to deliver a secondary payload or redirect users to a malicious site. No scripts were extracted from this sample, but the overall context points to a social engineering lure for malware distribution.
