LG Uplus, a leading telecommunications company in South Korea, has informed TechCrunch that it has notified the national cybersecurity authority KISA about a potential data breach. However, the company did not specify when the investigation findings would be released.
Over the last half year, all three major telecom operators in South Korea—SK Telecom, KT Telecom, and now LG Uplus—have disclosed cybersecurity incidents, though official confirmation from the Korean government is still pending.
The Ministry of Science and ICT in South Korea told TechCrunch that its probe into KT and LG Uplus, which began last month, is still underway. This comes after reports suggested that these companies might have suffered cyberattacks similar to the recent incident involving SK Telecom.
In July, KISA reportedly detected indications of a potential cyber intrusion and requested LG Uplus to submit an official report. The following month, LG’s telecom arm initially rejected claims of a breach, even as KT disclosed that unauthorized micro base stations had exposed user data on its network. KISA has not provided any comments on the matter.
This development follows about two months after the hacking publication Phrack alleged that hackers from China or North Korea had accessed data from nearly 9,000 LG Uplus servers.
LG Uplus’s disclosure comes as South Korea faces a series of major hacking incidents impacting telecom companies, credit card providers, technology startups, and government bodies, exposing security gaps previously highlighted by TechCrunch.
The country’s fragmented approach to cybersecurity and a lack of skilled professionals have made it difficult for South Korea to effectively address these cyber risks.
