MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF document contains numerous embedded URLs and a primary external URI pointing to a domain associated with game hacks and cheats. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related lures suggests an attempt to trick users into downloading further malware. No scripts were extracted from this sample, but the overall pattern indicates a phishing or social engineering attempt to deliver a payload.
