MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains an embedded URL pointing to a resource promising game cheats, and the ML classifier strongly flagged it as malicious. The document body, though heavily obfuscated, contains text related to earning Roblox currency and includes the same suspicious URL. This suggests the document is a lure to download a second-stage payload, likely related to game hacking or malware.
