The notorious group used its channel to leak huge volumes of sensitive data stolen from victims. Currently, the channel has close to 60,000 followers. Lapsus$ has operated openly on its Telegram chat channel since December 2021. Our systems and processes worked as designed, the intrusion was rapidly shut down and closed off, and the compromised credentials used were rendered obsolete." The systems accessed contained no customer or government information or other similarly sensitive information, and we have no evidence that the intruder was able to obtain anything of value. In direct response to Information Security Media Group's queries about this latest incident, T-Mobile says: "Several weeks ago, our monitoring tools detected a bad actor using stolen credentials to access internal systems that house operational tools software. The Washington-based telecommunications giant fell victim to another data breach early this year that was linked to a SIM swapping attack that it said affected "a very small number" of its 105 million customers (see: T-Mobile: Some Customers Affected by SIM Swap Data Breach). He reported that the chat messages show Lapsus$ breached T-Mobile several times and stole source code for a range of company projects.Ī spokesperson for T-Mobile told Krebs that its "monitoring tools detected a bad actor using stolen credentials to access internal systems that house operational tools software" but no sensitive customer or government information was stolen. Information security blogger Brian Krebs recently reviewed a copy of the private chat messages between members of the Lapsus$ cybercrime group before the arrest of its most active members last month.

The March attack happened through the company's email vendor and affected some customers and employees. Prior to this massive breach which affects nearly half of T-Mobile's over-100 million customers, the company reported being hacked twice in 2020, in March and then again in December. They said the breach came to light when a hacker began claiming in online forums he had millions of T-Mobile customer records to sell. "We have no indication that the data contained in the stolen files included any customer financial information, credit card information, debit or other payment information," the statement said, though it continued, "Some of the data accessed did include customers' first and last names, date of birth, SSN, and driver's license/ID information for a subset of current and former postpay customers and prospective T-Mobile customers." Their preliminary analysis showed that almost 8 million current postpaid customers and 40 million records of former or prospective customers who had at one point applied for credit with the company were taken in what the company called a "highly sophisticated cyberattack." This most recent breach is by far the largest and has affected at least 47 million current and former T-Mobile customers, according to numbers released by the mobile giant. The latest in the series of hacks on the company's millions of customers' data comes on the heels of two attacks in 2020, one in 2019, and another in 2018. T-Mobile confirmed their latest data breach affecting millions of customers in a statement on Tuesday, totaling five breaches in the last four years.
