Rowhammer Instruction Skip Attack: Bypassing Security Checks and Encryption in Real-World Applications
The LeapFrog attack leverages Rowhammer-induced bit flips in the Program Counter (PC) value stored in the stack to subvert the control flow of victim processes, enabling the bypass of security-critical code sections such as authentication checks and encryption routines.
Exploiting CPU Clock Modulation for Covert Communication Channel: A Novel Approach to Bypass Security Policies
A novel covert channel attack that exploits the duty cycle modulation feature of modern Intel processors to enable secret communication between two colluding processes, bypassing security policies.
