Port Scanning in JavaScript - SPI Dynamics

Port Scanning in JavaScript - SPI Dynamics

Imagine visiting a blog on a social site like MySpace.com or checking your
email on a portal like Yahoo’s Webmail. While you are reading the Web page
JavaScript code is downloaded and executed by your Web browser. It scans
your entire home network, detects and determines your Linksys router model
number, and then sends commands to the router to turn on wireless
networking and turn off all encryption. Now imagine that this happens to 1
million people across the United States in less than 24 hours.
This scenario is no longer one of fiction.

Welcome to the brave new world of Web 2.0
I love the fact that Steve Gibson's begging people to default browsers to disable Javascript. Backlash to AJAX on it's way.
