Concerns have arisen among players of League of Legends and Valorant regarding their security after allegations surfaced that the games' new anti-cheat software, Vanguard, might be taking unauthorized screenshots of players' entire screens, including potentially capturing private conversations in apps like Discord. Additionally, there have been reports that Vanguard is causing PCs to malfunction, commonly referred to as 'bricking'. Riot Games, the developer behind these titles, has responded to these claims, stating that there is no confirmed instance of Vanguard causing hardware issues, but acknowledged that some players might be experiencing problems.
