Samsung has been improving the security and privacy features of its devices and often boasts about its in-house Knox security system that protects its devices from malicious attacks. The Korean giant, however, recently suffered a data breach, in which a hacking group was able to acquire almost 190GB of Samsung’s internal data, including source codes for its Galaxy smartphones. The company confirmed the data breach in a recent statement.

Following reports of the data breach over the past weekend, Samsung confirmed that a hacking and data extortion group dubbed “Lapsus$” was able to steal 190GB worth of internal data from its repositories. The company confirmed it to Bloomberg recently.

Now, Samsung says that the data breach will not affect any of its customers as the hackers only stole the source codes and the company’s internal data. Furthermore, the company claims it has implemented improved security measures to prevent such attacks in the future.

However, according to a recent report by Bleeping Computer, the stolen data contains source code for every Trusted Applet (TA) installed in Samsung’s TrustZone environment, confidential source code from Qualcomm, and the full source code for the tech used for authorizing and authenticating Samsung accounts. The publication reports that if the details are accurate enough, it could cause huge damage to the company. So, if you are a Galaxy smartphone user, it is suggested that you keep your device up to date with the latest security patches to avoid losing your personal data to malicious actors.
