MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous URLs advertising hacks for popular games, with a primary URL pointing to 'netcdn.xyz'. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs and a 'download button' heuristic suggests a lure to download a second-stage payload. No scripts were extracted, but the overall pattern indicates a phishing or scam attempt.
