CT AG Tong Probes T-Mobile's 2021 Data Breach Affecting 53M

T-MobileMarch 2, 2022Connecticut Attorney General

Consumers Affected

53,000,000

Summary

In March 2022, Connecticut Attorney General William Tong announced that Connecticut is co-leading a multistate investigation into T-Mobile's 2021 data breach, which affected over 53 million individuals. The breach compromised sensitive data including names, dates of birth, Social Security Numbers, and driver's license information. Tong urged affected consumers to take protective steps such as credit monitoring and freezes.

Contract Impact

In-house legal teams should review all vendor, customer, and data processing agreements for clauses related to data security, breach notification timelines, data retention limits, and third-party data sharing. Specific attention should be paid to requirements for encryption of sensitive data like Social Security Numbers and driver's licenses, incident response procedures, indemnification for data breaches, and audit rights to verify security practices. Agreements may need amendments to mandate stronger encryption standards, shorten breach notification windows, limit collection/retention of high-risk personal data, and impose stricter controls on subprocessors.
