Police officers from National Police Agency show a seized computer which was used for hacking at the agency's headquarters in Seoul July 8. South Korean authorities issued a cyber-security warning on Wednesday after the Web sites of government agencies and financial institutions were disabled by apparent hacker attacks, possibly linked to North Korea.

A series of attacks on computer networks in South Korea and the US was apparently the work of North Korean hackers, several news agencies are reporting today. The attacks, which targeted the White House, the Pentagon, and the Washington Post, among other high-level institutions, are raising concerns that the long-simmering conflict with North Korea is expanding into a dangerous new theater.

According to Seoul's National Intelligence Service, the "attacks appeared to have been elaborately prepared and staged by a certain organization or state." In that statement, North Korea was not specifically named, but the Yonhap news agency said the NIS had traced the attacks to North Korea or pro-Pyongyang forces.

"The NIS has been telling committee members that North Korea or a pro-North Korean force might be behind the cyber terror," a South Korean legislator told Yonhap. The statement has not been independently verified, and South Korean intelligence agency say the matter remains under investigation.

Meanwhile, The Associated Press has obtained a list of the targets in a coordinated attack last weekend on US networks. Included on the list are the National Security Agency, the Department of Homeland Security, the State Department, and the Nasdaq stock exchange. Many of the organizations appeared to have successfully blunted the sustained computer assaults, the AP said.

In South Korea, the sites of the presidential office, the defense ministry, and the National Assembly were saturated with access requests generated by malicious software on Tuesday, crippling server response to legitimate traffic, South Korea's Communications Commission said in a statement.

A test

Many analysts see the attacks as a test of the US government's ability to deal with a coordinated cyber-attack.

In late May, President Obama unveiled the details of an ambitious new cyber-security initiative, which he said would gird the nation’s infrastructure against digital threats. “We rely on the Internet to pay our bills, to bank, to shop, to file our taxes,” Obama said in a news conference. “But we’ve had to learn a whole new vocabulary just to stay ahead of the cyber criminals who would do us harm – spyware and malware and spoofing and phishing and botnets."
