Microsoft has plugged a critical hole in all supported versions of Windows that allows attackers to hit high-value computers with self-replicating attacks that install malicious code with no user interaction required.
The vulnerability in the Remote Desktop Protocol is of particular concern to system administrators in government and corporate settings because they often use the feature to remotely trouble-shoot e-mail servers, point-of-sale terminals and other machines when they experience problems. RDP is also the default way to manage Windows machines that connect to Amazon’s EC2 and other cloud services. That means potentially millions of endpoints are at risk of being hit by a powerful computer worm that spreads exponentially, similarly to the way exploits known as Nimda and Code Red did in 2001.
