LG Uplus said on the 6th that it reported to the Personal Information Protection Commission that some call information from the artificial intelligence (AI) call app "Ixio" had been leaked.
LG Uplus explained that during recent operational improvements to the Ixio service, an error in cache (temporary storage) settings caused a temporary exposure of some information from 36 customers to 101 other users, including ▲ call counterpart phone numbers ▲ call times ▲ summaries of call content, and that it completed a report to the Personal Information Protection Commission at about 9 a.m. on the 6th.
The time during which personal information could have been leaked was between 8 p.m. on Dec. 2 and 10:59 a.m. on Dec. 3, during which the information was exposed to users (101 people) who newly installed or reinstalled Ixio, and, on an individual basis, it was exposed to between 1 and 6 other users.
LG Uplus said it confirmed that the leaked information did not include unique identifiers such as resident registration numbers or passport numbers, nor financial information.
LG Uplus said that as soon as it recognized the problem at about 10 a.m. on the 3rd, it began identifying the cause and carrying out restoration work, completing measures to ensure the exposed call information was no longer visible. It said it then guided all affected customers by phone and informed those difficult to reach via text messages and other means.
An LG Uplus official said, "We apologize for the inconvenience and concern caused to our customers," and added, "This matter is not related to hacking, and we will actively cooperate with subsequent investigations by the relevant authorities."
