MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text promoting 'hacks' and 'free items' for games, strongly suggesting a lure for users to download potentially malicious software. The ML classifier also flagged this PDF as malicious with high confidence. The primary IOC is the URL http://netcdn.tw/app/431946152/roblox-hack-download-pc-game-hack, which is likely the download source for the promised 'hack'. No scripts were extracted from this sample.
