In a time of hacker attacks on critical infrastructure, even a run-of-the-mill malware infection on an electric utility’s network is enough to raise alarm bells. But the latest collection of power grid penetrations went far deeper: Security firm Symantec is warning that a series of recent hacker attacks not only compromised energy companies in the US and Europe but also resulted in the intruders gaining hands-on access to power grid operations—enough control that they could have induced blackouts on American soil at will.

In light of the recent 700 million email data leak on August 30 of this year, I have created CredCheck. I would like to throw out a personal thanks to Troy Hunt owner and operator of HaveIBeenPwned. CredCheck is a windows program that uses the HaveIBeenPwned API to check email addresses and give details on who’s information has been leaked, and how severe the leak was.

Well last night I got an idea. I like to checkout the TOR Hidden Services from time to time but it’s a pain in the tail just trying to find a link that actually works. So I cooked up the OnionScanner! It’s basically just a TOR link checker. But feel free to check it out on the home site or on GitHub and let me know what you think. If you have some ways to improve on it feel free to put in a request. Even if you just want to port it to another language to make it cross-platform I would greatly appreciate it!
Anyways, just like I said I would I got into trying to actually demodulate the signal for that fan remote…well as it turns out, after tons of research it seems like the method I posted about in my last entry was the easiest way to “demod” a PWM signal, just doing it by hand. So I’ve moved on to other stuff. So, been working on attacks against Keyfobs today (that little button you use to unlock/lock your car) and so far so good. Here’s a screenshot of a little program I’m working on to make IDR (intercept, disrupt, replay) attacks on keyfobs a little easier. When it’s done it will basically sit there and listen for you to push a button, when you do it will jam the signal and save the signal to a file. Then when you push it again it will jam that signal, save the second one to a file, the replay the first one (causing your vehicle to lock/unlock as expected). Continue reading “Fun with Keyfobs!”
It’s been quite a while since I’ve last posted here so I figured I’d do a little experiment. I haven’t even touched my SDRs in a few months, but I recently purchased a HackRF and WIFI Pineapple (they haven’t arrived yet) so I figured I’d pull out my old dongles and brush up some on SDR and DSA. Well, I wanted to start with the simplest thing I could think of so I grabbed a remote control for our ceiling fans and decided I’d try to decode the signal.
