MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly flagged this PDF as malicious. The document contains multiple embedded URLs, including one pointing to 'netcdn.xyz' which appears to be a lure for game-related cheats. The presence of a visual download button heuristic further supports the intent to trick users into downloading content. No scripts were extracted, but the overall pattern suggests a phishing or malware distribution attempt.
