    There were claims that Lapsus$ breached Okta (an authentication provider of all things) and Microsoft a couple of days ago.

    Turns out those claims were true:

    And we're back to CPU tampering, affecting both Intel (Kaby Lake and Coffee Lake) and AMD (Zen 1, Zen 1+, and Zen 2) CPUs.

    Some microprocessors from Intel and AMD are vulnerable to a newly discovered speculative execution attack that can covertly leak password data and other sensitive material, sending both chipmakers scrambling once again to contain what is proving to be a stubbornly persistent vulnerability.

    [...]

    The mitigations will come at a cost that the researchers measured to be between 12 percent and 28 percent more computational overhead. Organizations that rely on affected CPUs should carefully read the publications from the researchers, Intel, and AMD and be sure to follow the mitigation guidance.

    If I read that article correctly, then 5000 series CPUs are immune?

    12 to 28% is absolutely huge in terms of performance hits and now both AMD and Intel are affected. Tbh if I were the tinfoil hat type I'd say not addressing potential security issues in development makes orgs keen to upgrade since CPU upgrades tend to be many years far in between :/
    Guns make the news, science doesn't.

    Maybe Intel and AMD should abandon speculative execution entirely?

    Didn't want to assume an article actually got it right so dove into the AMD disclosure. They are claiming Zen 3 CPU's are entirely unaffected, so yes.
