WASHINGTON (AP) -- A widespread and unusually resilient computer attack that began July 4 knocked out the Web sites of several government agencies, including some that are responsible for fighting cyber crime, The Associated Press has learned.
The Treasury Department, Secret Service, Federal Trade Commission and Transportation Department Web sites were all down at varying points over the holiday weekend and into this week, according to officials inside and outside the government. Some of the sites were still experiencing problems Tuesday evening. Cyber attacks on South Korea government and private sites also may be linked, officials there said.
U.S. officials refused to publicly discuss details of the cyber attack. But Amy Kudwa, spokeswoman for the Homeland Security Department, said the agency's U.S. Computer Emergency Readiness Team issued a notice to federal departments and other partner organizations about the problems and "advised them of steps to take to help mitigate against such attacks."
The U.S., she said, sees attacks on its networks every day, and measures have been put in place to minimize the impact on federal Web sites.
It was not clear whether other federal government sites also were attacked.
Others familiar with the U.S. outage, which is called a denial of service attack, said that the fact that the government Web sites were still being affected three days after it began signaled an unusually lengthy and sophisticated attack. The officials spoke on condition of anonymity because they were not authorized to speak on the matter.
Web sites of major South Korean government agencies, banks and Internet sites also were paralyzed in a suspected cyber attack Tuesday. Ahn Jeong-eun, a spokeswoman at the Korea Information Security Agency, said the U.S. and South Korean attacks appeared to be linked.
The South Korean sites included the presidential Blue House, the Defense Ministry, the National Assembly, Shinhan Bank, Korea Exchange Bank and top Internet portal Naver. They went down or had access problems since late Tuesday, Ahn said.
Kudwa had no comment on the South Korean attacks.
Two government officials acknowledged that the Treasury and Secret Service sites were brought down, and said the agencies were working with their Internet service provider to resolve the problem.
Ben Rushlo, director of Internet technologies at Keynote Systems, called it a "massive outage" and said problems with the Transportation Department site began Saturday and continued until Monday, while the FTC site was down Sunday and Monday.
Keynote Systems is a mobile and Web site monitoring company based in San Mateo, Calif. The company publishes data detailing outages on Web sites, including 40 government sites it watches.
According to Rushlo, the Transportation Web site was "100 percent down" for two days, so that no Internet users could get through to it. The FTC site, meanwhile, started to come back online late Sunday, but even on Tuesday Internet users still were unable to get to the site 70 percent of the time.
"This is very strange. You don't see this," he said. "Having something 100 percent down for a 24-hour-plus period is a pretty significant event."
He added that, "The fact that it lasted for so long and that it was so significant in its ability to bring the site down says something about the site's ability to fend off (an attack) or about the severity of the attack."
Denial of service attacks against Web sites are not uncommon, and are usually caused when sites are deluged with Internet traffic so as to effectively take them off-line. Mounting such an attack can be relatively easy using widely available hacking programs, and they can be made far more serious if hackers infect and use thousands of computers tied together into "botnets."
For instance, last summer, in the weeks leading up to the war between Russia and Georgia, Georgian government and corporate Web sites began to see "denial of service" attacks. The Kremlin denied involvement, but a group of independent Western computer experts traced domain names and Web site registration data to conclude that the Russian security and military intelligence agencies were involved.
Documenting cyber attacks against government sites is difficult, and depends heavily on how agencies characterize an incident and how successful or damaging it is.
Government officials routinely say their computers are probed millions of times a day, with many of those being scans that don't trigger any problems. In a June report, the congressional Government Accountability Office said federal agencies reported more than 16,000 threats or incidents last year, roughly three times the amount in 2007. Most of those involved unauthorized access to the system, violations of computer use policies or investigations into potentially harmful incidents.
The Homeland Security Department, meanwhile, says there were 5,499 known breaches of U.S. government computers in 2008, up from 3,928 the previous year, and just 2,172 in 2006.

Vast Spy System Loots Computers in 103 Countries
By JOHN MARKOFF
Published: March 28, 2009
TORONTO — A vast electronic spying operation has infiltrated computers and has stolen documents from hundreds of government and private offices around the world, including those of the Dalai Lama, Canadian researchers have concluded.

The Vast Reach of ‘GhostNet’
In a report to be issued this weekend, the researchers said that the system was being controlled from computers based almost exclusively in China, but that they could not say conclusively that the Chinese government was involved.
The researchers, who are based at the Munk Center for International Studies at the University of Toronto, had been asked by the office of the Dalai Lama, the exiled Tibetan leader whom China regularly denounces, to examine its computers for signs of malicious software, or malware.
Their sleuthing opened a window into a broader operation that, in less than two years, has infiltrated at least 1,295 computers in 103 countries, including many belonging to embassies, foreign ministries and other government offices, as well as the Dalai Lama’s Tibetan exile centers in India, Brussels, London and New York.
The researchers, who have a record of detecting computer espionage, said they believed that in addition to the spying on the Dalai Lama, the system, which they called GhostNet, was focused on the governments of South Asian and Southeast Asian countries.
Intelligence analysts say many governments, including those of China, Russia and the United States, and other parties use sophisticated computer programs to covertly gather information.
The newly reported spying operation is by far the largest to come to light in terms of countries affected.
This is also believed to be the first time researchers have been able to expose the workings of a computer system used in an intrusion of this magnitude.
Still going strong, the operation continues to invade and monitor more than a dozen new computers a week, the researchers said in their report, “Tracking ‘GhostNet’: Investigating a Cyber Espionage Network.” They said they had found no evidence that United States government offices had been infiltrated, although a NATO computer was monitored by the spies for half a day and computers of the Indian Embassy in Washington were infiltrated.
The malware is remarkable both for its sweep — in computer jargon, it has not been merely “phishing” for random consumers’ information, but “whaling” for particular important targets — and for its Big Brother-style capacities. It can, for example, turn on the camera and audio-recording functions of an infected computer, enabling monitors to see and hear what goes on in a room. The investigators say they do not know if this facet has been employed.
The researchers were able to monitor the commands given to infected computers and to see the names of documents retrieved by the spies, but in most cases the contents of the stolen files have not been determined. Working with the Tibetans, however, the researchers found that specific correspondence had been stolen and that the intruders had gained control of the electronic mail server computers of the Dalai Lama’s organization.
The electronic spy game has had at least some real-world impact, they said. For example, they said, after an e-mail invitation was sent by the Dalai Lama’s office to a foreign diplomat, the Chinese government made a call to the diplomat discouraging a visit. And a woman working for a group making Internet contacts between Tibetan exiles and Chinese citizens was stopped by Chinese intelligence officers on her way back to Tibet, shown transcripts of her online conversations and warned to stop her political activities.
The Toronto researchers said they had notified international law enforcement agencies of the spying operation, which in their view exposed basic shortcomings in the legal structure of cyberspace. The F.B.I. declined to comment on the operation.
Although the Canadian researchers said that most of the computers behind the spying were in China, they cautioned against concluding that China’s government was involved. The spying could be a nonstate, for-profit operation, for example, or one run by private citizens in China known as “patriotic hackers.”
“We’re a bit more careful about it, knowing the nuance of what happens in the subterranean realms,” said Ronald J. Deibert, a member of the research group and an associate professor of political science at Munk. “This could well be the C.I.A. or the Russians. It’s a murky realm that we’re lifting the lid on.”
A spokesman for the Chinese Consulate in New York dismissed the idea that China was involved. “These are old stories and they are nonsense,” the spokesman, Wenqi Gao, said. “The Chinese government is opposed to and strictly forbids any cybercrime.”
The Toronto researchers, who allowed a reporter for The New York Times to review the spies’ digital tracks, are publishing their findings in Information Warfare Monitor, an online publication associated with the Munk Center.
At the same time, two computer researchers at Cambridge University in Britain who worked on the part of the investigation related to the Tibetans, are releasing an independent report. They do fault China, and they warned that other hackers could adopt the tactics used in the malware operation.
“What Chinese spooks did in 2008, Russian crooks will do in 2010 and even low-budget criminals from less developed countries will follow in due course,” the Cambridge researchers, Shishir Nagaraja and Ross Anderson, wrote in their report, “The Snooping Dragon: Social Malware Surveillance of the Tibetan Movement.”
In any case, it was suspicions of Chinese interference that led to the discovery of the spy operation. Last summer, the office of the Dalai Lama invited two specialists to India to audit computers used by the Dalai Lama’s organization. The specialists, Greg Walton, the editor of Information Warfare Monitor, and Mr. Nagaraja, a network security expert, found that the computers had indeed been infected and that intruders had stolen files from personal computers serving several Tibetan exile groups.
Back in Toronto, Mr. Walton shared data with colleagues at the Munk Center’s computer lab.
One of them was Nart Villeneuve, 34, a graduate student and self-taught “white hat” hacker with dazzling technical skills. Last year, Mr. Villeneuve linked the Chinese version of the Skype communications service to a Chinese government operation that was systematically eavesdropping on users’ instant-messaging sessions.
Early this month, Mr. Villeneuve noticed an odd string of 22 characters embedded in files created by the malicious software and searched for it with Google. It led him to a group of computers on Hainan Island, off China, and to a Web site that would prove to be critically important.
In a puzzling security lapse, the Web page that Mr. Villeneuve found was not protected by a password, while much of the rest of the system uses encryption.
Mr. Villeneuve and his colleagues figured out how the operation worked by commanding it to infect a system in their computer lab in Toronto. On March 12, the spies took their own bait. Mr. Villeneuve watched a brief series of commands flicker on his computer screen as someone — presumably in China — rummaged through the files. Finding nothing of interest, the intruder soon disappeared.
Through trial and error, the researchers learned to use the system’s Chinese-language “dashboard” — a control panel reachable with a standard Web browser — by which one could manipulate the more than 1,200 computers worldwide that had by then been infected.
Infection happens two ways. In one method, a user’s clicking on a document attached to an e-mail message lets the system covertly install software deep in the target operating system. Alternatively, a user clicks on a Web link in an e-mail message and is taken directly to a “poisoned” Web site.
The researchers said they avoided breaking any laws during three weeks of monitoring and extensively experimenting with the system’s unprotected software control panel. They provided, among other information, a log of compromised computers dating to May 22, 2007.
They found that three of the four control servers were in different provinces in China — Hainan, Guangdong and Sichuan — while the fourth was discovered to be at a Web-hosting company based in Southern California.
Beyond that, said Rafal A. Rohozinski, one of the investigators, “attribution is difficult because there is no agreed upon international legal framework for being able to pursue investigations down to their logical conclusion, which is highly local.”
