"This flaw in Microsoft's code has only been known about for a handful of days, and already there is a worm which is taking advantage of the problem in its attempt to infect as many PCs as possible. Time and time again hackers are forcing companies like Microsoft to scrabble around to develop, test and roll-out a software patch," said Graham Cluley, senior technology consultant for Sophos. "Businesses should ensure that their computers are properly configured, and protected with up-to-date anti-virus software, hardened firewalls and patches." The worm can also exploit a vulnerability present in Symantec's anti-virus product line, which was patched a year ago. Microsoft has published an advisory on its website giving guidance to companies who may be affected by the flaw in its software. The news of the worm comes a week after Microsoft patched a series of other critical vulnerabilities in its software. "The computer underground appear to be revelling in waiting until Microsoft has released its monthly batch of patches, before unleashing their latest attacks," continued Cluley. "It's not just businesses who are being affected by this, Microsoft will not be enjoying having the security of their software brought into question again." Sophos suggests that every IT manager responsible for security should consider subscribing to vulnerability mailing lists such as that operated by Microsoft at www.microsoft.com/technet/security/bulletin/notify.mspx.{moscomment}
