New DRAM Scrambling Attack Exposes CPU’s Most Protected Memory Zones

A new attack technique that manipulates a computer’s memory controller to bypass some of the strongest hardware security boundaries built into modern processors, including protections around System Management Mode, the Platform Security Processor, and CPU microcode. The research, published as an open-source project called skitter-creek-bath-salts on GitHub by Security researcher Christopher Domas, has unveiled a striking attack […] The post New DRAM Scrambling Attack Exposes CPU’s Most Protected Memory Zones appeared first on Cyber Security News.
