Police have secured materials related to hacking damage that occurred at KT and Lotte Card and have begun an investigation.
On the morning of the 29th, National Office of Investigation Commissioner Park Seong-ju said at a regular press briefing that, regarding the KT server intrusion case, "We have launched a pre-charge inquiry and secured related materials held by KT." He added, "An investigation is now underway into how the hacking occurred and the scope of the damage." Earlier, on the night of the 18th, KT reported signs of a server intrusion to the Korea Internet & Security Agency (KISA).
Police said that, as of the 26th, they had received damage reports totaling a little over 240 million won from 218 victims in connection with the unauthorized small-payment incident at KT. The affected areas are eight locations: Gwangmyeong, Gwacheon, Goyang, and Bucheon in Gyeonggi Province; Geumcheon, Dongjak, and Seocho in Seoul; and Bupyeong in Incheon.
Police arrested two suspects in the case on the 17th, ethnic Chinese nationals identified as A, 48, and B, 44. They are currently investigating accomplices.
Police also launched a pre-charge inquiry into the Lotte Card hacking incident, in which customer information was leaked, and secured materials including the affected Lotte Card servers. Deputy Minister Park said some materials were secured through compulsory procedures, noting, "Although this is a pre-charge inquiry stage, it is effectively an investigative stage."
