T-Mobile is the target of a class action complaint that claims the company did not take “reasonable care” to protect the personal data of millions of customers from a data breach.

 

Root Cause Analysis:

The “bad actor” who was responsible for T-data Mobile’s breach used one of the company’s application programming interfaces (APIs) to manipulate users’ confidential data, including names, phone numbers, email addresses, billing addresses, dates of birth, account numbers, and service package specifics.

According to T-CEO, Mobile’s the hacker used “brute force” assaults to compromise the organization’s security. There were more than 37 million impacted customer profiles. In a prior hack in 2021, about 48 million social security numbers were accessed, affecting over 50 million T-Mobile users.

 

Detection:

The business asserts that it is aware of who carried out the assault and how servers were accessed without authorization. After gaining entry to the testing environment, the attacker entered other IT servers using brute force attacks and other techniques. T-Mobile has informed U.S. federal authorities about the incident, and is now collaborating with law enforcement to look into the security hole.

Response on the Data Breach:
