MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a heuristic firing for an external URI, all related to game hacks and cheats for Roblox and other games. The ML classifier strongly flagged this PDF as malicious. The document body text, though partially corrupted, includes phrases like "free shaggy roblox game hack" and links to download-related PDFs, suggesting a lure to download a second-stage payload. No scripts were extracted from this sample.
