Firms upgrading their computer systems to the Windows 2000 operating systems from NT 4 are exposing themselves to greater security risks from Web site defacement.
Records kept by security site Attrition.org indicate that an average of 55 per cent of Web site defacements so far this year are linked to exploitation of Windows NT operating systems vulnerabilities. Linux is the second most commonly hacked Web server and accounted for around 21 per cent of Web page defacement last month.
However buried within these figures is a trend of increased exploitation of sites running Windows 2000.
