Security researchers at Graz University of Technology in Austria discovered the fixes for the ZombieLoad speculative execution attacks on Intel processors were not completely effective. The researchers have disclosed a new variant that works on Intel processors that have hardware mitigations in place.
The OpenTitan chip project launched by Google and several partners will produce open-source designs for secure root of trust hardware.
Microsoft's Secured-core PC initiative is a partnership with OEM partners (including HP and Dell), silicon vendors (such as Intel, AMD, and Qualcomm) to provide deeply integrated hardware, firmware and software that can withstand firmware-based attacks.
Arm is bringing custom instructions to its Cortex-M processors. The overall security of these processors will depend on how these instructions are actually implemented.
A new attack that exploits a weakness in the DDIO feature of some Intel chips can leak sensitive data, including SSH keystrokes.
