Last week the Lapsus$ ransomware gang claimed to have stolen a huge trove of sensitive data from Samsung Electronics and leaked 190GB of alleged Samsung data as proof of the hack.

Now the company confirmed that the attack resulted in then exposure of sensitive company data.

“There was a security breach relating to certain internal company data,” Samsung told Bloomberg. “According to our initial analysis, the breach involves some source code relating to the operation of Galaxy devices, but does not include the personal information of our consumers or employees. Currently, we do not anticipate any impact to our business or customers. We have implemented measures to prevent further such incidents and will continue to serve our customers without disruption.”
