According to a VNA reporter in Seoul, the Korean telecommunications industry has just recorded a large-scale subscriber migration after SK Telecom announced a cyber attack that led to a leak of customer information.
In just one month, nearly 400,000 users have left the country's largest carrier to switch to rival networks such as KT and LG U+.
According to mobile telecommunications industry statistics, a total of 395,517 subscribers left SK Telecom between April 20 and May 21. Of these, 227,009 switched to KT and 174,808 switched to LG U+.
Meanwhile, the number of subscribers switching from KT and LG U+ to SK Telecom was only 43,567. Accordingly, the number of SK Telecom subscribers decreased by 351,950 in just 1 month.
In a press conference on May 22, SK Telecom announced that it will issue full SIM card replacement guidelines next week and soon lift the suspension of new registrations.
SK Telecom said that as of now, a total of 3.23 million users have completed SIM card replacements. There are currently 5.67 million pending reservations. The number of people who have reset their SIM cards has increased by 23,000, bringing the total to 170,000.
SK Telecom also announced plans to expand investment in information security in the medium and long term.
SK Telecom's public relations center head Kim Hee Seop said the company is conducting a network information security safety assessment, and affirmed that "the scale of investment will increase from the current level."
Meanwhile, the South Korean government has announced its intention to join discussions on a joint response to growing cybersecurity threats. The South Korean government is considering joint defense cooperation with three major domestic telecommunications companies.
Meanwhile, legal action by users affected by SKTelecom's integrated SIM (USIM) card hacking incident continues.
Attorney Kim Guk Il, a representative of Daeryun Law Firm, said at a press conference on May 22 that he plans to file a lawsuit early next week on behalf of about 1,000 SK Telecom users, demanding 1 million won in compensation for each person.
The USIM data leak was first discovered on April 18. In order to prevent identity theft or financial fraud, SK Group has offered to replace USIM cards for free for all 25 million subscribers, including 2 million low-cost phone users.
All subscribers are also automatically registered for the USIM protection service - a solution that SK Group claims is capable of protecting users from unauthorized financial activities./.
