🍪 Oreo: Securing ASLR Against Microarchitectural Attacks

MIT researchers have developed "Oreo," a new security method to protect computer hardware from microarchitectural side attacks. These attacks exploit hardware vulnerabilities to locate and access sensitive program code. Oreo works by masking the location of code within a computer's memory, preventing hackers from tracing its original locations. This innovative approach enhances the effectiveness of existing security measures like ASLR, improving the security of operating systems like Linux without significant performance impact. The researchers plan to extend this work to address other vulnerabilities, such as speculative execution attacks.
