It looks like T-Mobile has been involved in a new data breach after a cybercriminal claims to have hacked into T-Mo’s IT service and consulting partner, Capgemini.
The cybercriminal, aka grep, claimed that they broke into the Paris-based IT services and consulting company. They alleged that they were able to steal 20GB of sensitive information, which includes the database, source code, employee information, and credentials from Capgemini’s client roster.
The hacker claims they were able to gain access to T-Mo’s virtual machine logs, confidential information, and internal project files. The breach, along with samples, were announced through BreachForums.
Although Grep claims they were able to steal more data, they decided to focus on the large, confidential files. As PhoneArena reports, we don’t know yet if T-Mobile had already been alerted of the hack.
