T1566.001 Spearphishing Attachment

The PDF contains multiple embedded URLs and a document body that attempts to lure the user with promises of free in-game items. The ML classifier also flagged this PDF as malicious. The primary URL, https://netcdn.tw/app/431946152/how-to-get-a-free-gift-card-on-roblox-game-hack, is likely the destination for this social engineering attempt.
