User Hack on Zoom

[Griffin]

I was just on a zoom where the host had published the link on a public Facebook page (yeah, incredibly stupid thing to do, but people are stupid around technology) with the Zoom meeting having no security (unfortunately I did not know until too late). Needless to say, we got an unwanted guest who shook his bare behind at us.

That's a simple thing to do getting into the meeting by using the link but after a minute or so, this changed and became a duplicate of me as zoom user. He then sent chat messages as me. There were my original user presence plus another one as me so I appeared to appear twice. Would he have just entered my name as a duplicate so it looked like me talking, or would he have actually highjacked me in some way? What I need to know is how compromised am I? Is it restricted to that zoom session or does the hack method mean my laptop, or other web accounts are compromised? I can't find any answers googling this specific type of event.  (Meeting's host non-techy so can't ask him and can't access his zoom account to see attendees in zoom reports.)

Most likely he just changed the name on his session to be the same as you.  I do not believe you were hijacked: as far as I know this is not possible through Zoom.  I do not think your notebook will have been compromised in any way by this.

No, I don't think I am compromised. It was a shock to see two of me though.

Yes, I can understand that...
