Zoombombing: some quick advice not fully worked up (I'm ill, but want to get this out). It is a real risk: a bunch of savvy internet law types got horribly zoombombed last week. You probably underestimate just how horrible that can be, because you are not a horrible person. 1/5

1a. If you're in a meeting that gets zoombombed in a nasty way, SHUT THE MEETING DOWN IMMEDIATELY. Don't mess around trying to lock them out. The attacker does this for kicks the whole time & will run rings round you. Use a different medium to contact the legit participants. 2/5

1b. If they posted appalling stuff that's a criminal offence to share, be sure to report it to the police at the earliest opportunity (but not on the emergency line, obvs) and follow their advice. DON'T SEND ILLEGAL CONTENT TO ANYONE, for any reason. It's an absolute offence. 3/5

2. If you can choose a different tool, avoid Zoom. Zoom is very easy to use without faff and logins and passwords, and it's ubiquitous at the moment so most people know how to use it - but that's also what makes it a target. 4/5

3. If you do use Zoom, spend a bit of time getting to grips with how to reduce the chances of this happening. See e.g. https://blog.zoom.us/wordpress/2020/03/20/keep-uninvited-guests-out-of-your-zoom-event/ That is all a lot more fiddly and annoying, but Zoom's selling point is making it easy to do it at all, not easy to do it securely. 5/5
