Malicious software that takes advantage of a recently disclosed vulnerability in Microsoft Corp.'s Windows operating system has spread rapidly and has now infected more than 250,000 systems, primarily Windows 2000 systems being run in corporate environments, according to security vendor Computer Associates International Inc. (CA).
Microsoft Corp. security researchers are warning about a new generation of powerful system monitoring programs, or "rootkits," that are almost impossible to detect using current security products and that could pose a serious risk to corporations and individuals. The researchers discussed the growing threat posed by kernel root kits at a session at the RSA Security Conference in San Francisco on Tuesday. The malicious snooping programs are becoming more common and could soon be used to create a new generation of mass-distributed spyware and worms.
