A sizable chunk of Internet traffic made an unnoticed pit stop in Belarus and Iceland at several points over the past year, a security firm said today. Renesys, a company that monitors online activity, says some Internet traffic was hijacked en route to the US and other locations, including government destinations as part of a scheme of unknown origin. Victims whose traffic was diverted varied by day, and included major financial institutions, governments, and network service providers. On that list are places like the US, Germany, South Korea, and Iran.
