‘Close Enough’ Data Breach Notifications Create Exposure

BakerHostetler attorneys note that T‑Mobile disclosed an August 2021 breach exposing 76 million records (about 47 million SSNs). The Washington Attorney General filed suit in January 2025 alleging T‑Mobile violated state consumer protection and data breach notification laws by sending text-message notices to 361,030 Washington residents instead of the statutorily required notice methods, highlighting substantial regulatory and financial risk tied to notification noncompliance.
