Warning Issued Against Fast-Spreading Hacking Worm An information security institute reported a new hacking tool that is spreading quickly between companies and personal computers in Korea. The Korea Information Security Agency (KISA) said yesterday the worm, known as Carko, is similar in potency to last year's worm that severely damaged some high-profile websites such as Yahoo! and CNN. The agency's computer forensics experts expressed concern that cases of the new virus will increase just as distributed denial-of-service (DDoS) tools did last year.
DDoS tools can flood a single website or Internet server with so much data, and from so many sources that the computer effectively would disappear from Internet.
