Mystery W2K attacks show need for patches
Malicious code is being downloaded onto Windows 2000 servers in a series of attacks that bypass anti-virus software and underline...
Microsoft is baffled by these latest exploits and will only say that a "significant number" of servers have been affected.
Gunter Ollmann, manager of Internet Security Systems' X-force security assessment service, said the problem does not appear to be a worm but may be an automated brute force attack that searches the Internet for vulnerable servers.
Brute force attacks usually bombard servers with a dictionary of potential passwords to find a victim but Ollmann said this may be a variant that seeks out unsecured ports.
The attacks could be extremely serious because the exploit installs a backdoor to systems for future access and can change Active Directory security permissions to create unauthorised accounts with administrator privileges.
