SYSTEMS UP. South Korean companies recover after a cyberattack.

MANILA, Philippines - Following a concerted cyber attack on the computer systems of a number of South Korean broadcasting stations and banks, the Yonhap News Agency reports that the affected companies have recovered their networks, though there is still work to be done on fixing individual computers and gadgets.

An official for Korean Broadcasting System (KBS), one of the affected companies, said, "We successfully recovered our mainstay network related to programming and advertising this morning, and normalized our service."

He added, however, that KBS is "still working to recover around 5,000 personal computers that came under the attack, and our Web site is still unaccessible."

AFP quoted South Korean officials as saying part of the malicious code found on the Nonghyup bank system originated from an IP address in China. The identity of the hackers could not be confirmed, however. - Rappler.com
