Conficker Worm Could Create World's Biggest Botnet 220
nk497 writes "The worm that's supposedly infected almost nine million PCs running Windows, dubbed Cornficker or Downadup, could lead to a massive botnet, security researchers have said. The worm initially spread to systems unpatched against MS08-067, but has since 'evolved and is now able to spread to patched computers through portable USB drives through brute-force password-guessing.'"
