Koizumi Web site made visitors' data vulnerable to hackers03/15/2002 Link(dead as of 10/27/06):http://home.kyodo.co.jp/all/display.jsp?an=20020314004 TOKYO, March 13, Kyodo - The Internet site of Prime Minister Junichiro Koizumi's office poses the danger that the personal data of visitors to the site can be obtained by hackers, a Web security research company said Wednesday. The defect was found on the page called ''We Solicit Your Opinions,'' a segment of the site which is also the source of the e-mail magazine of the prime minister, said Vagabond Co. based in Tokyo. Vagabond alerted the prime minister's office of the presence of the security problem Monday. The prime minister's office suspended the operations of the page in question on Wednesday, because the Vagabond warning took two days before reaching the official in charge of the site, a cabinet official said. The prime minister's office is trying to fix the security defect and eliminate the problem by Thursday morning. The official said, ''It remains unknown whether personal information of the people who visited this site was passed on'' to hackers. ''The possibility is very low,'' the official said. The official also denied suggestions that personal data of subscribers to the premier's e-mail magazine might have been stolen by any hacker. Government sources said the site -- until it was suspended -- posed the danger that if a hacker had posted a special computer program for stealing the personal data of visitors, it could have passed such data on to the hacker. This possibility of leakage of data to an unguarded Web site is known as the vulnerability of cross-site scripting.
