What was exposed

Youku’s breach included 2 kinds of data. What each lets criminals do:

Data	What it’s used for
Passwords	Criminals try leaked passwords on email, banking and shopping sites, because people reuse them.
Email addresses	Expect scam emails that name the company to look genuine.

Check whether you’re in it.Search your email address on Have I Been Pwned. It tells you which breaches it appears in, Youku among them, without showing the data.
Change your Youku password.If the account still exists, sign in at Youku (youku.com) and change it.
Change it anywhere you used the same one.Start with your email, then banking and shopping. Leaked passwords are tried on other sites automatically, within days.
Use a password manager and two-step sign-in.A different password for every site means one breach can’t open the rest. Two-step sign-in stops a leaked password working on its own.
Distrust messages that mention Youku.Scammers use breach data to sound genuine. Don’t click links in emails or texts about the breach; go to the site yourself.
