Too Curious For My Own Good: Jam Intercept and Replay Attack against Rolling Code Key Fob Entry Systems using RTL-SDR For the past 6 months I have been developing a proof of concept attack against rolling code key fob entry systems. Some examples of affected systems would be the key fob you use to unlock your car. Or the key fob you use to disarm your home security system. Or even open the garage door. The oscillators used in these key fobs are typically low cost, meaning that they may not operate at exactly their design frequency throughout the full temperature range.

mitmproxy — mitmproxy 0.17 documentation mitmproxy is a console tool that allows interactive examination and modification of HTTP traffic. It differs from mitmdump in that all flows are kept in memory, which means that it’s intended for taking and manipulating small-ish samples. Use the ? shortcut key to view, context-sensitive documentation from any mitmproxy screen. hackme: Deconstructing an ELF File A friend recently asked me to find the password for a little hard-to-hack program he had written and I agreed to it. The short journey of a few hours that led me to its password were extremely interesting and this article describes the process as well as some of the new techniques learnt along the way. Few minutes after accepting his challenge, I received a binary called "hackme" in an E-mail and I got started! Those interested in giving it a shot can download the binary file and get back to this article later. Do let me know if you find anything interesting along the way that I did not think of or missed!

Extremely severe bug leaves dizzying number of software and devices vulnerable Researchers have discovered a potentially catastrophic flaw in one of the Internet's core building blocks that leaves hundreds or thousands of apps and hardware devices vulnerable to attacks that can take complete control over them. The vulnerability was introduced in 2008 in GNU C Library, a collection of open source code that powers thousands of standalone applications and most distributions of Linux, including those distributed with routers and other types of hardware. A function known as getaddrinfo() that performs domain-name lookups contains a buffer overflow bug that allows attackers to remotely execute malicious code.
