S.Korean police: Hackers extracted data in attacks
Hackers extracted lists of files from computers that they contaminated with the virus that triggered cyberattacks last week in the United States and South Korea, police in Seoul said Tuesday.
The attacks, in which floods of computers tried to connect to a single Web site at the same time to overwhelm the server, caused outages on prominent government-run sites in both countries.
The finding means that hackers not only used affected computers for Web attacks, but also attempted to steal information from them. That adds to concern that contaminated computers were ordered to damage their own hard disks or files after the Web assaults.
Still, the new finding does not mean information was stolen from attacked Web sites, such as those of the White House and South Korea's presidential Blue House, police said. It also does not address suspicions about North Korea's involvement, they said.
Police reached those conclusions after studying a malicious computer code in an analysis of about two dozen computers — a sample of the tens of thousands of computers that were infected with the virus that triggered the attacks, said An Chan-soo, a senior police officer investigating the cyberattacks. The officer said that only lists of files were extracted, not files themselves.
