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.

LG Uplus, a major mobile carrier in South Korea, reported a cyberattack on its servers on October 23, the latest data breach to be reported in a series of recent industry-wide breaches.

According to industry sources, LG Uplus submitted a report to the Korea Internet and Security Agency (KISA) early on October 22 after detecting signs of an attack attempt.

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

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

However, in August, LG Uplus informed the Ministry of Science and Information Technology that an internal audit found no specific evidence of a cyber attack.

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

In April, SK Telecom, South Korea's top carrier, revealed a massive leak of universal subscriber identity module (USIM) data from its servers, prompting the company to offer free replacement USIMs to all users.

Last August, KT also reported that 368 users' data was exposed after illegal micro base stations were connected to its network, resulting in unauthorized micropayments worth 240 million won ($174,000)./.
