Ministry of Science and ICT Inspects SKT and LG Uplus Femtocells Ahead of 'Hacking Hearing'

Management Systems Inspected After Micro-Payment Hacking Incident
KT Excluded from Review Due to Ongoing Separate Investigation

The Ministry of Science and ICT has launched an emergency inspection of femtocell (ultra-small base station) management systems at SK Telecom and LG Uplus, following the recent KT hacking incident. With concerns over femtocell security being raised daily ahead of the National Assembly hearing, the government has moved quickly to respond.

According to reporting by Asia Economy on September 23, the Ministry of Science and ICT inspected the status of femtocell holdings, management procedures, and any inappropriate connections at SK Telecom and LG Uplus on September 22. A ministry official explained, "Similar to the inspection for malware infections during the SK Telecom hacking incident in the first half of the year, this time we directly examined the femtocell management systems," adding, "Rather than conducting a full-scale inspection of each device, we focused on reviewing the management systems and security procedures."

Femtocells are small base stations installed by mobile carriers to improve indoor call quality, serving as substitutes for regular base station signals in homes or small offices. While they have been rapidly adopted due to their convenience and low cost, concerns have been raised about their vulnerability to hacking. The recent KT incident has once again highlighted that if femtocells are illegally modified or connected without authorization, they can be exploited to facilitate fraudulent micro-payment transactions.

According to industry estimates, KT owns the largest number of femtocells among the three major telecom operators, with approximately 160,000 units. In KT's case, a joint public-private investigation team is currently conducting a detailed investigation, so KT was excluded from this round of inspections by the Ministry of Science and ICT. In contrast, SK Telecom and LG Uplus, with about 10,000 and 30,000 femtocells respectively, were subject to a comprehensive review of their management systems, despite having fewer units. The government's decision to inspect these two companies just before the hearing is seen as a response to pressure from the National Assembly, which has called for a review of the overall safety of the telecommunications sector, not just KT.

In fact, the National Assembly has repeatedly raised the issue of femtocell security in recent days. Lawmakers have pointed out "inadequate femtocell management" and stressed the need to "verify the safety of other telecom operators as well." The Ministry of Science and ICT's last-minute inspections ahead of the hearing are closely linked to this political climate. At the Science, ICT, Broadcasting, and Communications Committee hearing scheduled for September 24, inadequate femtocell security management, the government's follow-up response, and the debate over corporate responsibility are expected to be key issues. Witnesses and reference persons called to the hearing include Kim Youngsub, CEO of KT, security executives from SK Telecom and LG Uplus, Kim Byungjoo, Chairman of MBK Partners, Cho Jwajin, CEO of Lotte Card, and Kim Seungjoo, Professor at Korea University Graduate School of Information Security.
