Intercepting Predator Video

A Tour Of A “Pay to Download Firefox” Site
At Mozilla , we regularly get anguished emails from people who have paid to download Firefox, and have then discovered a) that it's actually free, and b) that it's very hard to get the company they paid to stop charging their credit card. For those who have never had the misfortune to visit one of these trap sites, I…

Advanced SSH Techniques
At one site where I provide technical assistance, access to the network is all done via ssh over the Internet. However, one can't get access to the machines directly; one must first make an ssh connection to a gateway box I'll call martha. martha doesn't allow one to use regular passwords or keys, though.

Massive Twitter Cross-Site Scripting Vulnerability
I bet 10 years ago none of us thought that 140 characters would change the landscape of Social Media quite so much. However, with close to 289,000,000 active users sending around 6,000 tweets every second Twitter has proven its critics wrong. Obviously, having gotten over …

Arbitrary code execution via ldd utility
The `ldd` utility is more vulnerable than you think. It's frequently used by programmers and system administrators to determine the dynamic library dependencies of executables. Sounds pretty innocent, right? Wrong! In this article I am going to show you how to create an executable that runs arbitrary code if it's...

Bcrypt is now obsolete
I am speaking today at BSDCan'09 about my work on the scrypt key derivation function. In the context of hardware brute-force attacks, scrypt is thousands of times more secure than existing "best practice" solutions such as bcrypt and PBKDF2; in fact, under reasonable assumptions it is provably as strong as possible…

Apple Rejects EFF Updates App, because it links "objectionable" youtube video
Last month, EFF got an email from software developer Duane Fields of Exact Magic, asking if he could use our logo on an iPhone application that exclusively displays content from EFF's RSS feed. Sounded like a great idea to us, as long as it was clear that the app wasn't an EFF-sponsored product.But...

Stop Password Masking
Usability suffers when users type in passwords and the only feedback they get is a row of bullets. Typically, masking passwords doesn't even increase security, but it does cost you business due to login failures.

Faking votes on Hacker News
Hacker News is a site where users vote on links. When someone clicks on an up or down vote, their browser sends a GET request that looks like this: GET /vote?by= joesmith dir=upfor=8765309 A user can only vote if the by parameter matches their Hacker News login cookie. So for a third…

Encrypt-then-MAC
First things first: Why use a composition of encryption and MAC instead of a single primitive which achieves both? Because people are very good at writing bad code. In my experience on the FreeBSD security team, writing dozens of security advisories, there are three types of code which are especially prone to have…
