Thanks to Keith Furman for the tip: Counterpane, a security consulting firm, on Monday announced that it had found serious security problems in Windows NT that threatens any NT networks that are connected to the Internet.
"We were able to sniff passwords, eavesdrop on the networks, and passively do traffic analysis," said Bruce Schneier, president of Counterpane. "Any Microsoft NT server on the Internet is insecure."
The flaws affect those NT networks that known as Virtual Private Networks (VPN), those networks that let users remotely connect via the Internet and TCP/IP. VPNs have become very popular in the past year as mobile workers increase in number, needing to access corporate networks remotely.
Interestingly, Microsoft has already acknowledged the problem and is working on a fix. This fix will likely be released as a hot-fix to Service Pack 3 and will also be included in Service Pack 4, due soon.
