MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains multiple embedded URLs that lead to sites offering free game-related downloads, such as Minecraft texture packs and Robux. The ML classifier flagged this PDF as malicious with a high probability. The presence of these lures and the ML detection suggest the document is designed to trick users into downloading potentially harmful content.
