If your Kakao account has been, or may have been, logged-in (accessed) by an individual with unlawful intentions, then you must immediately register again by verifying your phone number, change your Kakao account password, and re-connect to KakaoTalk.
Contact your local police station or file a report with the Cyber Terror Response Center if you wish to investigate the incident.
You must not unregister from KakaoTalk if you wish to file a report, and you may have difficulties in the investigation if you have not experienced any damage.
Kakao does not have the right to investigate such matters, and we would like to ask for your understanding if we are unable to directly resolve possible damages.
We will submit all necessary information upon request from the police and fully cooperate with the investigation.
