Silver Golub & Teitell LLP represents several current and former T-Mobile customers in connection with a data breach that occurred on January 5, 2023 (the "2023 T-Mobile Data Breach"). If you were a T-Mobile customer on or before January 5, 2023, your personal information may have been compromised in this breach. To be clear, T-Mobile has confirmed this is a distinct incident from the incident that occurred in 2021.
On January 19, 2023, T-Mobile US, Inc. (T-Mobile) announced it had suffered a data breach on January 5, 2023 when a bad actor obtained customer information through an API without authorization. T-Mobile claims it promptly began an investigation and has since traced and contained the malicious activity. Approximately 37 million T-Mobile customer accounts, including names, addresses, and account information, were affected. T-Mobile is continuing to investigate the breach, working with law enforcement and federal agencies, and has notified affected customers. T-Mobile has been making significant investments in enhancing their cybersecurity and protecting customer data remains a top priority. While the full impact of the breach is unknown, T-Mobile does not expect it to have a material effect on their operations."
API's, or "Application Programming Interface(s)" provide applications with access to data and the ability to interact with web databases through instructions. If not properly secured, APIs can be exploited by malicious individuals to obtain large amounts of information stored in these databases, such as what appears to have occurred here. T-Mobile customers should anticipate phishing scams exploiting public concern about the breach, where phishers impersonate the company and send messages that may include the recipient's breached account information to appear legitimate. The stolen and exposed data in this breach can also lead to identity theft.
