Attorney General Kathleen Jennings urges all Delaware residents who
believe they were impacted by the data breach announced by T-Mobile in
August 2021 to take appropriate steps to protect their information
from identity theft.

On August 17, T-Mobile reported a massive data breach compromising the
sensitive personal information of millions of current, former, and
prospective T-Mobile customers. The breach impacted more than 53
million individuals, including over 148,000 Delaware residents. Among
other categories of impacted information, millions had their names,
dates of birth, Social Security Numbers, and driver's license
information compromised.

Recently, a large subset of the information compromised in the breach
was for sale on the dark web - a hidden portion of the Internet where
cyber criminals buy, sell, and track personal information. Many
individuals have since received alerts through various identity theft
protection services informing them that their information was found
online in connection with the breach, confirming that impacted
individuals are at heightened risk for identity theft.
