SEOUL, March 22 (Yonhap) -- Some of the malicious codes that paralyzed network systems at South Korean banks and TV broadcasters originated from a local computer, Seoul's communications watchdog said Thursday.
The Korea Communications Commission (KCC) had earlier announced the malicious codes came from a Chinese Internet Protocol (IP) address, fueling speculations on North Korea's involvement in the attack that crippled networks at TV broadcasters KBS, MBC and YTN along with Shinhan, NongHyup and Jeju banks on Wednesday.
In a press release, the KCC said it had mistaken a private IP address used by NongHyup as an official IP address allocated to China.
The communications watchdog, however, did not elaborate on the attacker.
Meanwhile, the KCC said Shinhan and Jeju Bank have completely recovered their networks, while NongHyup is still in the process of normalizing its system.
TV broadcasters KBS, MBC and YTN have recovered roughly 10 percent of their attacked systems, the watchdog said, adding that no further damages have been detected.
