Preventing these kinds of attacks is a practical application of small Faraday containers. See mattblaze.org/blog/faraday
I understand the convenience of these key fobs, but the manufacturers really should equip them with a hard off switch (which would be cheaper and simpler than needing to store them in a shielded container).
And before you say "this only affects rich people with fancy cars", this kind of technology makes it way into cheap cars very quickly. It's like saying "look at the fancy car with AIR CONDITIONING".

The rich people with fancy cars are debugging this for the rest of us.
As a non-driver, however, I can occupy a small position of smugness here.

TIL that (possibly) the first (civilian) college course in cryptography was taught in 1941 my alma mater, @Hunter_College. Whether it was actually the first such course is a good question, but this is fascinating in any case. nytimes.com/1941/09/28/arc…
@Hunter_College Hunter was, at the time, a women-only college focused on training teachers (though this course, in the evening session, may have also been open to men). The instructor was a locally famous architect, Rosario Candela, who had recently successfully broken a french military cipher.
@Hunter_College The NYT archive is unfortunately paywalled, but everything in the article is amazing. Image

I'm not going to give more O2 to that dreadful voting article that came out the other day. But I will say that "don't find things out or tell other people about them because bad people might misinterpret them out of context" is a weird premise for a journalist to start from.
Anyway, as a scientist and academic, I'm committed to the value of finding things out and telling others about them, even when they're complicated, subject to disingenuous misinterpretation, or inconvenient.
I also take pains to try to put my work in context, but that doesn't always survive sloppy malicious compression into soundbites.

Been playing the "enter your grades" video game and I'm really tired of feeding quarters into this machines.
It looks really simple. I just have to shoot the correct grade into each student's space ship before any of them reach the bottom of the screen.
In all seriousness, while the mechanics of grading (and the need to make hard decisions) indeed sucks, I've really been enjoying reading these papers over the last few weeks. I've learned a lot, some of which will definitely get incorporated into future classes.

I wish I understood election security as well as random people on Twitter do.
According to the replies, people would like me if only I smiled more.
People with recently created accounts, few followers, and no obvious existence outside this web site sure do have strong opinions about how I should improve myself.

As we approach the anniversary of the January 6th attack on the Capitol, it is worth remembering that the premise of the riot - that widespread technical attacks subverted the 2020 election outcome - was entirely false. No actual election security expert found it at all credible.
As these specious, obviously fabricated claims started to be circulated in the aftermath of the election, my colleagues and I released this statement. To this day, there has been no credible evidence presented of fraud affecting the election outcome. mattblaze.org/blog/election-…
January 6th was the culmination of one of the worst-case scenarios in election security - a failure (in this case caused by lies and misinformation) to achieve widespread trust in an important election outcome. Fortunately, the rioters failed to achieve their objective.

No, I’m not linking to the lazy scam that didn’t get permission from me or any of the other prominent people whose names and images they’re exploiting.
Well, that was quick, at least. They claim to have taken mine down.

Pro tip: If you want to “honor” someone in a way that just so happens to make you money, ask them first.
Also, if you’re sending me a link to this thing or asking me to react to it, you’re not being helpful at this point. You’re just promoting it. If I don’t personally know you, I’ll probably assume that’s your motive in doing so.
