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…
We show that on the x86 it is possible to mount a return-oriented programming attack without using any return instructions. Our new attack instead makes use of certain instruction sequences that behave like a return; we show that these sequences occur with sufficient frequency in large Linux libraries to allow…
This is an excellent lesson in the security problems inherent in trusting proprietary software: After two years of attempting to get the computer based source code for the Alcotest 7110 MKIII-C, defense counsel in State v.

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.

It looks like Apple, Inc., is exploring a new business opportunity: spyware and what we're calling "traitorware." While users were celebrating the new jailbreaking and unlocking exemptions, Apple was quietly preparing to apply for a patent on technology that, among other things, would allow Apple...

To help preserve a safe Internet for content creators, we’ve just launched a brand new “easy button” to block all AI bots. It’s available for all customers, including those on our free tier
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...
China is the world’s most successful Internet censor. While the Great Firewall of China isn’t perfect, it effectively limits information flowing in and out of the country.
