During a press briefing, Park Hyun-soo, acting chief of the Seoul Metropolitan Police Agency, said that cybercrime teams are analyzing server log records tied to malicious code discovered in the breach.
“We have found overseas IP addresses during the analysis and are conducting international cooperative investigations,” Park said.
Police did not disclose the countries involved but confirmed they are working in conjunction with the National Intelligence Service. The scope of the collaboration suggests a broader effort to trace the source of the hack, which has raised alarms over potential foreign interference in the country's critical communications infrastructure.
When asked whether the foreign IP addresses indicated that the cooperating nations had served as conduits for the attackers, officials declined to elaborate.
“We are in the process of verification and cannot say that anything has been definitively established,” Park said.
Speculation has circulated that China or North Korea may be connected to the breach. However, investigators emphasized that no conclusions have been reached. Authorities continue to examine the origin of the attack, including whether it bears hallmarks of state-sponsored activity.
The breach, discovered in April, targeted South Korea’s largest telecommunications provider and is believed to have compromised the personal data of a significant portion of SK Telecom’s user base.
