MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a primary external URI pointing to sites offering game hacks and free in-game currency. The ML classifier strongly flagged this PDF as malicious, and the presence of these lures suggests an attempt to trick users into downloading malware or visiting malicious sites. No scripts were extracted, but the document structure and embedded URLs indicate a phishing or malware distribution attempt.
