Team is working through this right now.

If you've never tried @yup, you account is unaffected.

If you have, Settings -> Advanced -> Connected Apps and remove.

Update: in touch with the Yup team.

Also working on analyzing what accounts might have had unusual casts recently.

Will end up having a public retro.

Update: Deleted the original cast in the quote cast since it's a bug, not a compromise. Team is still investigating.

Chatting with Yup team, looks like it was an accident from their side.
