Amazon SES compromised

Solution 1:

The email is saying "notificationType" of "bounce". That suggests to me AWS SES is notifying you of a bounce (email returned rather than delivered), as described in this page, with bounce types here. The message has your "bounceType" as "Permanent" the docs say "The recipient's email provider sent a hard bounce message, but didn't specify the reason for the hard bounce."

Someone is clearly using AWS SES to send emails for your domain, and they're not arriving. If it's not you or your company I suggest you contact AWS abuse team about this (link). If you report yourself and it's another part of your company bad things may happen, so check carefully.
