A total of 23 SK telecommunications servers have been affected that store all four types of USIM data, including the IMSI information (International Mobile Subscriber Identity), reports Yonhap News Agency

The IMSI is a clear connoisseur for every user in a network and can possibly be exploited in financial transactions.

Among the affected servers were used as temporary memory for personal data such as names, birthdays, telephone numbers and e -mail addresses.

The investigators said they are still working to determine the exact scope of the data that are stored on these two servers.

The team said that there was no evidence of a data injury between December 3, 2024 and April 24 of this year, according to the Hackers' available Firewall protocol data.

Between June 15, 2022 and December 2, 2024, however, no protocol data was available, which made it impossible to confirm whether leaks occurred during this time frame.

SK Telecom discovered the violation on April 18. In response to this, the company offered to replace the Usasim of all 25 million subscribers, including 2 million budget telephone users, free of charge to prevent identity theft or finance fraud.

The company has also inscribed all users in the USIM Protection service, which, as it says, offers the same protection against non -authorized financial activities as a physical USIM replacement.
