Epsilon's solution
In response to the data breach, Epsilon took several measures to enhance security and prevent future incidents. The company entered into a deferred prosecution agreement with the Consumer Protection Branch of the Justice Department's Civil Division and the U.S. Attorney's Office for the District of Colorado. Epsilon agreed to pay a total of $150 million, with $127.5 million going to compensate victims of the fraudulent schemes that used consumer data sold by Epsilon.

What should affected users do?
In general, affected users should:
Change Your Password: Immediately update your password for the affected account. Make sure the new password is strong and unique, not previously used on any other platform.
Reset Passwords for Other Accounts: If you've used the same or similar passwords for other online accounts, reset those as well. This is crucial as attackers often try using stolen passwords on multiple sites.
