South Korea’s telecommunications provider LG Uplus said Saturday it reported to authorities that call data of customers using its artificial intelligence (AI)-based call app ixi-O was leaked early this week.
“Due to a cache configuration error, the call data of 36 customers, including the users’ phone numbers and content of their conversations, was temporarily exposed to 101 other users during our service update,” the telecommunications provider said in a statement.
“We reported the leakage to the Personal Information Protection Commission today at 9 a.m.,” the company added.
LG Uplus said the data leakage occurred between 8 p.m. Tuesday and 10:59 a.m. the following day, and the call information of existing users was revealed to those who newly downloaded or re-downloaded the app.
No sensitive information, such as users’ resident registration numbers or financial data, was exposed, the company added, noting the incident has “nothing to do with hacking.”
The telecommunications firm said it immediately began investigating the cause upon realizing the data leak at 10 a.m. Wednesday.
It also completed measures to ensure the users’ call information is no longer exposed to other users, while notifying affected users via text and phone calls.
“We sincerely apologize for causing concern and inconvenience,” the company said. “We will actively take part in any follow-up investigation from authorities.”
