Bizarro & Scary Happening in Zoom meeting today

Today in my zoom meeting, I was getting messages as if there was another user in the meeting with my name as the host. This other user was asking for permissions, to record, to share, etc. and I said no. When I started to screenshare, they wrote "kill" on my screen somehow with annotations. I cannot figure out how a zoom bomber got into the meeting and did this. I have changed passwords since but this was awful!
