The massive Twitter data breach is real. Here is a small offer of proof. There is data from entire countries in the data set.
@chadloder Oh fuck, I'm out of the loop, do I need to be scared?
Any actions you'd recommend to secure my account or anything?
@Zeitless @chadloder was last year as far as I know. But it turns out it was far worse than initially reported.
@Zeitless @chadloder actions depends on what's critical to you. The email and phone number was leaked, perhaps more (don't know. I don't have the data but assume the worst: password in salted form, DMs etc.)

Action: On all plattforms change your password if you reuse the password you are using on Twitter. You shouldn't do that irregardless of the breach.
