Don’t be eval()

JavaScript is an interpreted language, and like so many of its peers it includes the all powerful eval() function. eval() takes a string and executes it as if it were regular JavaScript code. It’s incredibly powerful and incredibly easy to abuse in ways that make your code slower and harder to maintain. As a general rule, if you’re using eval() there’s probably something wrong with your design.

Understanding the Greasemonkey vulnerability

If you have any version of Greasemonkey installed prior to 0.3.5, which was released a few hours ago, or if you are running any of the 0.4 alphas, you need to go and upgrade right now. All versions of Greasemonkey aside from 0.3.5 contain a nasty security hole, which could enable malicious web sites to read any file from your hard drive without you knowing.

Fighting RFCs with RFCs

Google’s recently released Web Accelerator apparently has some scary side-effects. It’s been spotted pre-loading links in password-protected applications, which can amount to clicking on every “delete this” link — bypassing even the JavaScript prompt you carefully added to give people the chance to think twice.

Giving away the index

My final year project is due in two weeks, and I’m going to be running on silent for most of them. I have, however, upgraded to Tiger and playing with Spotlight has given me plenty to think about.

The Register hit by XSS

Here’s a nasty one: popular tech news site The Register was hit on Saturday by the Bofra exploit, a nasty worm which uses an iframe vulnerability in (you guessed it) Internet Explorer to install nasty things on the victim’s PC. Where it gets interesting is that the attack wasn’t against the Register themselves; it came through their third party ad serving company, Falk AG.
