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

The PDF document contains numerous embedded URLs and a document body that explicitly offers cheats and hacks for games like Roblox and Minecraft. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related text suggests a lure to download further malicious content. The primary IOC is the initial URL found in the document, which likely leads to a malicious download.
