Microarchitectural Side-Channel Attacks and Countermeasures in RISC-V Processors

Quick fact

Even RISC-V processors, despite their clean, open-source design, are vulnerable to Spectre and Meltdown attacks because they use speculative execution and caching—features that create stealthy side channels leaking secrets through timing differences.

Why this is interesting

Your computer's processor is silently trying to guess the future—and that guesswork can be turned into a spy tool. What if the very chip in your device could be tricked into revealing your passwords?
