The number of illegal base station IDs suspected of being used for unauthorized small-amount payments at KT and the number of victims exposed to hacking have surged, according to confirmations.
According to lawmaker Hwang Jeong-a of the Science. ICT. Broadcasting. and Communications Committee on the 16th, KT's illegal base station IDs increased from the previous 4 to 20, and the number of people who connected to the illegal base stations rose by about 2,000 from the previous 20,030 to about 22,000.
Additional victims who suffered unauthorized small-amount payments were also found, within 10 people.
Given that personal information such as the victims' mobile phone numbers connected to the illegal base stations, International Mobile Subscriber Identity (IMSI), and International Mobile Equipment Identity (IMEI) had been leaked, concerns are being raised that the information of the additional 2,000 or so people may also have been leaked.
However, it is not known whether KT notified the additional victims about whether their devices connected to the illegal base station IDs, or whether it additionally reported the matter to the Personal Information Protection Commission.
KT counts 362 victims in the unauthorized small-amount payment case, while police put the number at 220 as of the 13th.
Hwang Jeong-a said, "KT's lie, which tried to gloss over the situation as if there were no additional damages, has finally been exposed," adding, "Punitive sanctions must be imposed for KT's repeated and malicious downplaying and cover-up."
