In January 2025, the WA attorney general sued T-Mobile over a data breach that affected 2M residents (this was the 79M T-Mobile breach). One of the issues in the litigation was that T-Mobile didn't properly notify those affected of the breach -- it omitted telling them in SMS notifications that their SSN had been acquired.
