A cybersecurity breach has compromised Samsung source code data related to the operational of its Galaxy devices, the company said Monday. Nonetheless, no personal information of Samsung customers or employees was exposed, according to an initial analysis done by the company. 

“We were recently made aware that there was a confidence breach relating to certain internal company data,” Samsung said in an email to CNET. “Immediately once discovering the incident, we strengthened our security system.” 

Samsung has not requested who it believes is responsible for the breach, but Lapsus$, a hacking group that reportedly stole data from Nvidia, claimed responsibility on Friday after posting a 190GB torrent file to Telegram, according to Bloomberg. 

Samsung said that it doesn’t put a question to the breach to impact its business or customers and that it has put preventive measures in assign to block future incidents.
