SEOUL, Oct. 23 (Korea Bizwire) – LG Uplus Corp., a major mobile carrier in South Korea, reported a cyberattack on its servers to authorities Thursday, industry sources said, the latest in a series of recent industry-wide data breach cases.
According to the sources, LG Uplus submitted a report earlier in the day to the Korea Internet and Security Agency (KISA) after detecting signs of a hacking attempt.
It came three months after KISA was alerted by a white-hat hacker to a possible breach of LG Uplus’ servers and notified the company of the warning in July, the sources said.
Phrack, an online cybersecurity publication, also reported that a hacking group had infiltrated LG Uplus’ intranet and leaked the data of about 42,000 customer accounts and 167 employees.
LG Uplus told the Ministry of Science and ICT in August that its internal inspection had found no concrete evidence of a cyberattack.
With LG Uplus now under scrutiny, all three of the country’s major telecom operators have faced data security incidents this year.
In April, industry leader SK Telecom Co. disclosed a major leak of universal subscriber identity module (USIM) data from its servers, prompting the company to offer free USIM replacements to all of its users and an investigation by the regulator.
In August, KT Corp. reported that data belonging to 368 users had been exposed after illegal micro base stations were connected to its network, resulting in 240 million won (US$174,000) in unauthorized micropayments.
