What was exposed

Trillian’s breach included 6 kinds of data. What each lets criminals do:

DataWhat it’s used for
PasswordsCriminals try leaked passwords on email, banking and shopping sites, because people reuse them.
UsernamesHalf of a login. With a reused password, it opens other accounts.
Dates of birthUsed to prove who you are to banks and phone companies.
NamesMakes scam messages personal enough to believe.
Email addressesExpect scam emails that name the company to look genuine.
IP addressesRoughly where you were when you used the service.

What to do

  1. Check whether you’re in it.Search your email address on Have I Been Pwned. It tells you which breaches it appears in, Trillian among them, without showing the data.
  2. Change your Trillian password.If the account still exists, sign in at Trillian (trillian.im) and change it.
  3. 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.
  4. 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.
  5. Distrust messages that mention Trillian.Scammers use breach data to sound genuine. Don’t click links in emails or texts about the breach; go to the site yourself.
