MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that explicitly mentions "Roblox Working Fly Hack 2021", suggesting a lure for users seeking game cheats. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple external URIs indicates an attempt to redirect the user to download potentially harmful content. No scripts were extracted, but the overall structure and content point to a phishing or malware distribution attempt.
