Just a reminder - there have been numerous fraudulent accounts created on the Fediverse lately pretending to be Mastodon Security, and asking for your credentials in DMs to you.

DO NOT RESPOND. DO NOT CLICK.

We will never ask you to verify your credentials. Period.

Tell your friends.

Them: You’re a security person, do you use public Wi-Fi?

Me: Nope

Them: Because it’s so unsafe and easy to hack you?

Me: Because it requires me to go out in public.

Great write-up here by @blowdart on *why* BinaryFormatter is bad and going away: https://github.com/dotnet/announcements/issues/293

This is the best single summary I’ve seen and for the widest audience. If you’re using BinaryFormatter anywhere, use this to help convince decision makers it needs to go bye bye from your codebase.
