Security firm warns that 'design weaknesses' in Windows Smart App Control mean it can be easily bypassed


Smart App Control is just one of various security features Microsoft has built into Windows 11. But while many users place faith in the tool to block malicious apps, Elastic Security Labs warns that it is fundamentally flawed.
The company says that Windows Smart App Control and its predecessor SmartScreen "have several design weaknesses that allow attackers to gain initial access with no security warnings or popups". In an investigatory report, Elastic Security Labs details numerous types of attack that can be used to bypass Windows Smart Control as well as revealing a bug in the handling of .lnk files which can be used to get around security.
