eEye has created a scanner which will detect and flag IP addresses that are vulnerable to the coming latest worm attack. Microsoft released patches on Tuesday that prevent this attack. Once they did that, hackers reverse engineered the patch to pinpoint the vulnerability. In spite of the Microsoft patch, many users do not regularly download these updates and are therefore at risk.
eEye Digital Security to the rescue. Download the free scanner and it will check the IP addresses for up to 16 computers and tell you if you are vulnerable. All you have to provide is a valid email address. That is a pretty good deal to me.
