LG Uplus Confirms Cybersecurity Incident

Recent Data Breach Reports at LG Uplus

LG Uplus, a leading telecommunications company in South Korea, has officially notified the Korea Internet & Security Agency (KISA) regarding a potential data security incident. However, the timeline for the investigation’s findings remains undisclosed.

Multiple Telecoms Affected

This report follows similar cybersecurity incidents reported by the other two major South Korean telecom providers: SK Telecom and KT Telecom. Confirmation of these incidents is still pending from the Korean government.

Ongoing Government Investigation

The South Korean Ministry of Science and ICT has stated that its investigation into both KT and LG Uplus, initiated last month, is currently in progress. This investigation stems from reports suggesting potential cyberattacks mirroring the recent breach experienced by SK Telecom.

Initial Denial and Subsequent Report

KISA initially detected indications of a possible hack at LG Uplus in July, requesting a formal report. Initially, the company’s telecom division refuted any evidence of a breach in August.

This denial occurred concurrently with KT’s announcement of user data exposure resulting from the connection of unauthorized micro base stations to their network. KISA has not provided any public comment on the matter.

Claims of Data Theft

Approximately two months ago, the hacking publication Phrack alleged that hackers, potentially originating from China or North Korea, had successfully stolen data from nearly 9,000 LG Uplus servers.

Widespread Cybersecurity Concerns

LG Uplus’s report is part of a broader pattern of significant cyberattacks impacting various sectors in South Korea. These include telecommunications, financial institutions, technology companies, and governmental bodies.

These incidents underscore vulnerabilities that have been previously identified.

Challenges Facing South Korea’s Cybersecurity

South Korea’s cybersecurity infrastructure is characterized by fragmentation. Furthermore, a deficiency in skilled cybersecurity professionals is impeding the nation’s ability to effectively address escalating cyber threats.
