Hackers attack LG Uplus network, leak data of tens of thousands of accounts

South Korean carrier LG Uplus's internal network was hacked, causing data of more than 42,000 customers and employees to be leaked, extending a series of cybersecurity incidents in the South Korean telecommunications industry.

On October 23, LG Uplus, a major mobile carrier in South Korea, reported a cyberattack on its servers. This is the latest data breach reported after a series of industry-wide violations recently.

According to industry sources, LG Uplus filed a report with the Korea Internet Security Agency (KISA) early on October 22nd after detecting signs of an attempted hack.

Notably, this incident occurred three months after KISA was alerted in July by a white-hat hacker (a hacker who specializes in exploiting computer systems or networks to identify security vulnerabilities and provide early warnings) about the possibility of LG Uplus's servers being compromised.

Phrack, an online cybersecurity publication, also reported that a group of hackers had infiltrated LG Uplus's internal network and leaked data from approximately 42,000 customer accounts and 167 employees.

However, in August, LG Uplus informed the Ministry of Science and Technology that its internal investigation found no concrete evidence of a cyberattack.

With LG Uplus now under close scrutiny, all three of the country's major telecommunications carriers have faced data security incidents this year.

In April, SK Telecom, South Korea's leading mobile carrier, revealed a major leak of Universal Subscriber Identity (USIM) module data from its servers, forcing the company to provide free replacement USIMs to all users.

Last August, telecommunications company KT also reported that the data of 368 users was leaked after illegal micro-base stations were connected to their network, resulting in unauthorized micro-payments worth 240 million won (US$174,000).
