      So yeah, it was just compromised internal credentials with the ability to take over user accounts. This is a big no-no and clearly the controls around those internal tools were woefully inadequate. This points to deficient security culture inside Twitter.https://twitter.com/TwitterSupport/status/1283591848729219073 …

      Hector Martin added,

      We know they used this access to take control of many highly-visible (including verified) accounts and Tweet on their behalf. We’re looking into what other malicious activity they may have conducted or information they may have accessed and will share more here as we have it.

      Also, that the internal account takeover happened at *all*, presumably remotely, is inexcusable in 2020. If your corporate authentication does not require non-spoofable 2FA (e.g. U2F/WebAuthn) to achieve this level of access, you are doing many things wrong.

      And apparently Twitter is retaliating against users tweeting screenshots of the internal tool (even censored of private info), which speaks volumes as to their priorities during this kind of massive security incident.

      Remember this is apparently a *support tool*. The issue of insider access from *engineers* is a tricky one, because ultimately engineers need to be able to engineer the system. It's possible, but tricky, to build sufficient controls around engineering procedures.

      It is not clear that this was a support account that was accessed rather than an engineering account. Engineers often have access to support tools, especially if they are responsible for them.

      Possible, but it's getting far-fetched. Whoever did this was clearly an idiot and didn't think through the consequences of their actions. Engineers are less likely to attempt something this dumb, IME.

      Usually when I've seen people go against policy at a big corp like this, it was either complete idiots doing something dumb, or someone smart who truly believed in what they were doing (e.g. whistleblowing) and then the latter don't get caught easily.

      Loading seems to be taking a while.
