Goto your Amazon account, sign out of all your devices, everything, everywhere all your Echos (yes I know it's a pain), reset your password, delete 2FA and any tokens and reset them. Now.
That doesn't include Fido / Yubikeys but does include Auth tokens.
Do it now.
As much a pain as it is to reset Echo and all smart devices, trust me, please do it.
I can't tell you more yet, but I am being ethical and you need to actually realise I have a clue.
It's been a scary day
I'm not fully buying it, because Amazon accounts and AWS accounts are intrinsically linked and the alarms would've rang a lot louder than a post on Mastodon.
But it's not harmful to update passwords and rotate 2FA credentials... so probably worth doing if you own AWS things.
Did anything seem to come of this? There was a whole bunch of stuff on his mastodon for a day or so, but it's all been deleted now (/the links go to a 404) including the original post.
