Microsoft discovers a vulnerability in its domain name server but says it may take weeks to deliver a patch, and the W32/Delbot-AI worm promptly launches attacks using that flaw. Two research houses predict that pinpointed attacks on select companies will soon replace broadly targeted worms as the greatest threat to corporate computer security. At a Usenix conference, experts warn that botnets -- which use a collection of compromised computers to steal financial data or send spam -- are getting increasingly complex and more capable of taking over more computers and accessing important data.
That was just some of the bad security news that came out in a single week this spring. While information security teams still struggle to plug new holes in technology and avoid broadly targeted viruses, they have to keep an eye on the threat of a carefully architected and targeted multi-vector attack.
