LAPSUS$ Attacks on T-Mobile Targeted Company’s Source Code

LAPSUS$ conducted an attack on T-Mobile that was confirmed by now discovered chat messages from the threat group.


Lapsus (stylizes LAPSUS$) has been making headlines this year through several high-profile attacks and important arrests of people associated with the group. In the latest information, KrebsOnSecurity reviewed a private chat message between members of LAPSUS$ regarding a breach on T-Mobile.

The chat happened in the week before active members of the group were arrested last month. During March, the threat group was able to steal the source code for a selection of the company's products and services.

However, T-Mobile insists no customer or government data was compromised during the breach. LAPSUS$ was targeting employees of T-Mobile, taking advantage of their access to the company's services. This allows SIM swap attacks, which involves reassigning a target mobile number to a device controlled by the group.

One of the most interesting things about LAPSUS is how quickly the group arose and how potent it became. It was only first seen in December 2021 and in the early months of 2022 carried out attacks on Vodafone, Samsung, and Nvidia.

Also, confirmed the group was behind an attack against Bing, Bing Maps, and Cortana. In March, the other interesting – amazing actually – thing about LAPSUS$ is the group was comprised by a bunch of kids. In March, City of London police arrested teenagers associated with the group, including the leader.

Reports point to a disgruntled Lapsus customer who doxed the mastermind behind the group and led to the arrests. In a special report, Krebs on Security said the leader bought the Doxbin sit that allows people to share personal information on other people.

However he is said to have been a poor website operator and sold the site in January, but not before releasing the whole Doxbin dataset online. To retaliate, the community doxed him.
