Hackers infringed Samsung's internal data: 

Samsung said on Monday that hackers violated its internal firm data, acquiring access to some source codes of Galaxy-branded gadgets like smartphones.

The report from the South Korean electronics giant comes after hacking company Lapsus$ claimed over the weekend through its Telegram channel that it has looted 190 gigabytes of secret Samsung source code.

Neither did Samsung name any distinct hackers in its announcement nor what specific data was misappropriated.

"We were later made aware that there was a security violation relating to specific internal company data.

Directly after discovering the happening, we maintained our security system," a Samsung representative informed CNBC.

"According to our initial investigation, the breach concerns some source codes linking to the operation of Galaxy devices, but does not have the personal data of our customers or workers."

Samsung's customer products, such as smartphones and tablets, are under the Galaxy trademark.

The company stated it does not expect any effect on its business or clients.

Lapsus$ is the same group that claimed blame for a data violation of chip giant Nvidia the previous month.
