T-Mobile Fined $60 Million for Data Breach Failures

The penalty marks the largest ever imposed by the Committee on Foreign Investment in the US, following violations tied to the Sprint merger.

CFIUS found T-Mobile failed to prevent and report unauthorized data access in 2020 and 2021.
The breaches involved data from law enforcement information requests but did not impact customer information.
T-Mobile attributed the breaches to technical issues during its integration with Sprint.
This is part of an increasing trend of CFIUS imposing more frequent and severe penalties.
T-Mobile is also in the process of acquiring US Cellular for $4.4 billion.
