@kylerankin Takeaway 1: Matrix response to take down prod, rebuild from scratch in relatively short order, is commendable and all orgs should be aim to be able to do the same in similar circumstances.
@kylerankin 2a: One approach is CI signing/shipping code to dev repo, admin logs into prod to trigger prod pkgs sync from dev to prod. Make attacker have to backdoor the code itself.
@kylerankin 3: Great early post-mortem given circumstances. Affected servers, what attackers did, what Matrix did, what users should do, timelines, promises of more detail later.
@kylerankin it seems it's still not over. or at least something very strange is going on in matrix website.
