T1566.001 Spearphishing Attachment

The PDF document contains a lure related to hacking Robux for the game Roblox, directing users to download a file from a suspicious URL. The ML classifier flagged this PDF as malicious with high confidence. While no scripts were explicitly extracted, the presence of embedded URLs and the document's theme suggest it is designed to trick users into downloading and executing a malicious payload.
