A new browser extension called Behave! will warn you if a web site is using scripts to perform scans or attacks on local and private IP addresses on your network. When browsing the web, scripts embedded on web pages can be used to not only port scan a visitor’s computer for open TCP ports, but also initiate attacks on other devices on your network.
Created by Stefano Di Paola, co-founder, CTO, and Chief Scientist of MindedSecurity, the Behave! browser extension was born as an experiment to warn users of web sites that abuse browser features to perform local attacks or scans on a visitor’s computer.
