A couple of computer security issues

The latest Crypto-gram is out, and it’s got the usual good stuff in it. Two things that stand out are the Witty Worm, and a letter on computer security (the last one).

The Witty worm is particularly scary because it was so well written (700 bytes!) and so destructive (infected 100% of targeted systems in 45 minutes). The only reason it wasn’t a major story is that the worm targeted only systems running a particular company’s security software, and there were only a limited number of installations.
