The U.S. telecom carrier T-Mobile has confirmed that the Lapsus$ ransomware group has breached its internal network by compromising employee accounts, according to multiple media reports. But, it says, hackers did not steal any sensitive customer or government information during the incident.
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.
He reported that the chat messages show Lapsus$ breached T-Mobile several times and stole source code for a range of company projects.
