Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      Another AMT flaw. It's important to note that this requires *physical access* to exploit. There are few threat models likely to be impacted by the issue. That said, it's a big deal for those who regularly leave laptops unsecured, particularly overseas.https://thehackernews.com/2018/01/intel-amt-vulnerability.html …

      This isn't a flaw. It's a misconfiguration. It doesn't hurt to spread the message to change the default password, though.

      Default passwords are an entire class of flaw. There should never be pw-based access unless user opts in by setting one.

      How do you get in to begin with to config then? No password a better solution? Sure, you can have console access-but that requires password as well. This is a misconfig. Hard-coded creds on the other hand is a flaw because you don’t know about it, and you can’t change it.

      In general, local console only for initial setup, enter password or configure pubkey access or whatever at setup time.

      For this specific issue, there's no expectation of any local access control unless you set a BIOS password, but when you do set a BIOS pw, there should not be an enabled-by-default AMT bypass to go around it!

          You know it’s enabled by default -when you initially set it up, disable it - set a long password - again config. If you know you will never use it - type a really long random password. Now if it doesn’t allow a really long password - that is a flaw.
