MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains numerous embedded URLs, many of which are disguised as links to free in-game items or currency for popular games like Coin Master and Roblox. The ML classifier strongly flagged this PDF as malicious, and the presence of these lures suggests an attempt to trick users into downloading further malicious content or visiting phishing sites. No scripts were extracted from this sample.
