U.S. and South Korean authorities yesterday were investigating the 
source of attacks on at least 35 government and commercial Web sites in 
the two countries, officials said.

In the United States, the attacks primarily targeted Internet sites 
operated by major government agencies, including the departments of 
Homeland Security and Defense, the Federal Aviation Administration and 
the Federal Trade Commission, according to several computer security 
researchers. But The Washington Post's site was also affected.

South Korea's main spy agency, the National Intelligence Service, said 
in a statement that it thought the attacks were carried out "at the 
level of a certain organization or state" but did not elaborate. The 
South Korean news agency Yonhap and the JoongAng Daily, a major 
newspaper in Seoul, reported that intelligence officials had told South 
Korean lawmakers that North Korea or its sympathizers were prime 
suspects. A spokesman for the intelligence service said that it could 
not confirm the report.

The attacks were described as a "distributed denial of service," a 
relatively unsophisticated form of hacking in which personal computers 
are commanded to overwhelm certain Web sites with a blizzard of data. 
The effort did not involve the theft of sensitive information or the 
disabling of crucial operational systems, government and security 
experts said. But they noted that it was widespread, resilient and aimed 
at government sites.
