Another system breach occurred on T-Mobile, this time at the hands of underage hackers

LAPSUS$ was obsessed with obtaining source code from tech companies. The gang used to gain initial access to its targets by buying credentials from sites like Russian Market. The trickier part was gaining access to internal company tools.

According to Krebs on Security, the cyber-crime gang Lapsus$, which has previously attacked NVIDIA, Samsung, and Microsoft, was able to gain access to T-networks Mobile’s many times in March. LAPSUS$ was allegedly controlled by a group of youngsters, and the group’s most active members are currently behind bars. Krebs on Security received a week’s worth of private discussions between top LAPSUS$ members, providing insight into the group’s tactics.

Highlights

  • LAPSUS$ gained access to the internal customer accounts management tool Atlas on March 19 and explored high-profile T-Mobile accounts associated with the FBI and Department of Defense. They weren’t able to go any further than that because those accounts required additional verifications before any changes could be made.

  • They relentlessly targeted T-Mobile employees and were able to breach the carrier’s system multiple times last month, giving them access to source code for a range of projects. The rogue group briefly considered SIM swaps, which would have let them hijack someone else’s number, which could have allowed them to conduct activities like password resets.

He was also able to download over 30,000 source code repositories from T-Mobile. It looks like this is when their access was revoked, as, in the words of White, “Cloning 30k repos four times in 24 hours isn’t very normal.” LAPSUS$ may had intended to target high-profile T-Mobile accounts – T-Mobile suffers another system breach, this time at the hands of teen hackers. LAPSUS$ may had intended to target high-profile T-Mobile accounts. T-Mobile has confirmed the attacks but has assured that the hackers weren’t able to steal any customer or government information.

The group leader, who is believed to be a 17-year-old from the U.K. and is referred to by nicknames “White,” “WhiteDoxbin,” and “Oklaqq,” eventually terminated the VPN connection that let them access T-Mobile’s network. He then proceeded to gain access to the carrier’s Slack and Bitbucket accounts.

Several weeks ago, our monitoring tools detected a bad actor using stolen credentials to access internal systems that house operational tools software. 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. Our systems and processes worked as designed, the intrusion was rapidly shut down and closed off, and the compromised credentials used were rendered obsolete. This is the seventh data breach T-Mobile has confirmed since 2018. A few days back, the carrier warned customers about unblockable phishing attacks.
