Chip-busting boffins in America have devised yet another way to filch sensitive data by exploiting Intel’s processor design choices.
Doctoral student Riccardo Paccagnella, master’s student Licheng Luo, and assistant professor Christopher Fletcher, all from the University of Illinois at Urbana-Champaign, delved into the way CPU ring interconnects work, and found they can be abused for side-channel attacks. The upshot is that one application can infer another application’s private memory and snoop on the user’s key presses.
