In a Zero-Day World, It’s Active Attacks that Matter

The recent zero-day vulnerability in Internet Explorer caused many (present company included) to urge Internet users to consider surfing the Web with a different browser until Microsoft issued a patch. Microsoft did so last month, but not before experts who ought to have known better began downplaying such advice, pointing out that other browser makers have more vulnerabilities and just as much exposure to zero-day flaws.

This post examines hard data that shows why such reasoning is more emotional than factual. Unlike Google Chrome and Mozilla Firefox users, IE users were exposed to active attacks against unpatched, critical vulnerabilities for months at a time over the past year and a half.

The Wikimedia Foundation last week warned that readers who are seeing ads on Wikipedia articles are likely using a Web browser that has been infected with malware.

Facebook Takes Aim at Cross-Browser ‘LilyJade’ Worm

Facebook is attempting to dismantle a new social networking worm that spreads via an application built to run seamlessly as a plugin across multiple browsers and operating systems. In an odd twist, the author of the program is doing little to hide his identity, and claims that his “users” actually gain a security benefit from installing his software.

At issue is a program that the author calls “LilyJade,” a browser plugin that uses Crossrider, an emerging programming framework designed to simplify the process of writing plugins that will run seamlessly across multiple browsers and operating systems, including Google Chrome, Internet Explorer, and Mozilla Firefox. The plugin spreads by posting a link to a video on a user’s Facebook wall, and friends who follow the link are told they need to accept the installation of the plugin in order to view the video. Users who accept the terms of service for LilyJade will have their accounts modified to periodically post links that help pimp the program.
