That would throw the country into financial chaos and could ultimately make it leave the eurozone.___ NKorea suspected in cyberattack despite China link SEOUL, South Korea (AP) â¿¿ Investigators have traced a coordinated cyberattack that paralyzed tens of thousands of computers at six South Korean banks and media companies to a Chinese Internet Protocol address, but it was still unclear who orchestrated the attack, authorities in Seoul said Thursday. The discovery did not erase suspicions that North Korea was to blame. An IP address can provide an important clue as to the location of an Internet-connected computer but can easily be manipulated by hackers operating anywhere in the world. The investigation into Wednesday's attack could take weeks. By Thursday only one of the six targets, Shinhan Bank, was back online and operating regularly. It could be next week before the other companies have fully recovered. ___ Average for US jobless claims at 5-year low WASHINGTON (AP) â¿¿ The number of people seeking U.S. unemployment aid barely changed last week, while the average over the past month fell to a five-year low. The decline in layoffs is helping strengthen the job market. Weekly unemployment benefit applications rose by 2,000 to a seasonally adjusted 336,000, the Labor Department said Thursday. Over the past four weeks, the average number of applications has dropped by 7,500 to 339,750. That's the lowest since February 2008, three months into the recession. ___ US homes sales highest in more than 3 years WASHINGTON (AP) â¿¿ U.S. sales of previously occupied homes rose in February to their fastest pace in more than three years, and more people put their homes on the market. The increases suggest a growing number of Americans believe the housing recovery will strengthen. The National Association of Realtors said Thursday that sales increased 0.8 percent in February from January to a seasonally adjusted annual rate of 4.98 million. That was the fastest sales pace since November 2009, when a temporary home buyer tax credit boosted sales. The February sales pace was also 10.2 percent higher than the same month a year ago.
