Wireless Client Update Posted by Sean @ 13:45 GMT

Windows XP SP2 Update KB917021 was published on October 17th 2006. What's that you say?


It's an update to "help prevent the Windows wireless client from advertising the wireless networks in its preferred networks list". Those of you that travel with confidential information might want to investigate this patch. It wasn't included in Microsoft's monthly updates.

Advertising the name of your preferred networks creates the potential for a man-in-the-middle attack. This patch won't stop your Windows notebook from using a spoofed network, but it will fix it so that the hacker would have to guess the name.

You can find more details on this from Brian Krebs and Knowledge Base article 917021. You can download it from Microsoft's Download Center – Validation Required.
