I don't like passkeys | Ethan Hawksley
Why passkeys are a step back for personal security: examining account lockout risks, platform lock-in, hardware key limits, and fragile recovery flows.

A GitHub project shows AMD Family 16h DRAM settings can alias protected memory, but it needs root access, a kernel module, and machine-specific calibration. It is not a universal CPU break. #AMD #Cybersecurity #ComputerSecurity
AMD’s Old DRAM Swizzle Is Real. the Universal Break Is Not
Skitter Creek Bath Salts is a credible proof of concept for AMD Family 16h processors: with privileged access, it can alter a DRAM controller’s address mapping and calculate an ordinary physical-address alias for data in protected memory. That is a serious result on the hardware it tested, but it is not yet a demonstrated defeat of memory protections across modern AMD, Intel, ARM, or RISC-V systems…

3 signs your computer might need a security check:

🔴 It's slower than it used to be
🔴 You haven't updated your OS in months
