AG Ferguson files lawsuit against T-Mobile for massive data breach

SEATTLE — Attorney General Bob Ferguson filed a consumer protection lawsuit today against T-Mobile for failing to adequately secure sensitive personal information of more than 2 million Washingtonians. That failure resulted in a massive data breach that exposed the personal information of those consumers and made them vulnerable to fraud and identity theft.

The lawsuit, filed in King County Superior Court, asserts that T-Mobile knew for years about certain cybersecurity vulnerabilities and did not do enough to address them. At the same time, T-Mobile misrepresented to consumers that the company prioritizes protecting the personal data it collects. Ferguson’s lawsuit also alleges T-Mobile failed to properly notify affected Washingtonians of the data breach, downplaying its severity and sending notices to affected consumers that did not disclose all the information that had been compromised.

In short, the lawsuit asserts that the massive data breach was a direct result of T-Mobile’s lack of accountability and failure to adhere to industry cybersecurity standards.
