Police stated they are expanding international cooperation investigations related to the SK Telecom hacking incident.
A Seoul Metropolitan Police Agency official noted at a regular press briefing on the morning of the 16th, "Determining who conducted the hacking attack is a priority," adding, "We are currently enhancing and expanding international cooperation with Interpol and related corporations." They further mentioned, "During the press briefing on the 2nd, I stated we are cooperating with at least three countries, and we are continuing to broaden the countries and scope," and noted, "We are analyzing in stages based on meaningful evidence."
When asked whether the suspect had been identified, the official replied, "It is still in the stage of ongoing tracking, so there is no matter I can confirm at this time."
It has been revealed that malicious code was installed on several server systems, including SK Telecom's Home Subscriber Server (HSS), in April, leading to a significant leak of sensitive personal information. Investigations by the Seoul Metropolitan Police Agency Cyber Investigation Unit, the National Intelligence Service, and the joint public-private investigation team of SK Telecom found that at least 25 types of malware had been installed since June 2022. SK Telecom advised its subscribers to replace their SIM cards for personal information protection, which caused a SIM card shortage.
Some speculate that North Korea or China may be involved, but police have stated that nothing has been identified at the investigative stage.
