MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The ML classifier strongly flagged this PDF as malicious. The document contains embedded URLs and a call-to-action button, directing users to download a "free Minecraft generator" from a suspicious domain. This suggests a lure to download a second-stage payload, likely for exploitation.
