It's hilarious, but the hilarity gets in the way of recognizing how much insight there is also there. It makes serious points. This part about the Mossad is especially astonishing given the pager attack:
> If your adversary is the Mossad, YOU’RE GONNA DIE AND THERE’S NOTHING THAT YOU CAN DO
ABOUT IT. The Mossad is not intimidated by the fact that you employ https://. If the Mossad wants your data, they’re going to use a drone to replace your cellphone with a piece of uranium that’s shaped like a cellphone
It's like a Mossad agent read this paper and thought hey that's actually not a bad idea.
But the core rant is about dubious assumptions in academic cryptography papers. I was also reading a lot of academic crypto papers in 2014, and the assumptions got old real fast. Mickens mocks these ideas:
• "There are heroes and villains with fantastic (yet oddly constrained) powers". Totally standard way to get a paper published. Especially annoying were the mathematical proofs that sound rigorous to outsiders but quietly assume that the adversary just can't/won't solve a certain kind of equation, because it would be inconvenient to prove the scheme secure if they did. Or the "exploits" that only worked if nobody had upgraded their software stack for five years. Or the systems that assume a perfect implementation with no way to recover if anything goes wrong.
• "you could enlist a well-known technology company to [run a PKI], but this would offend the refined aesthetics of the vaguely Marxist but comfortably bourgeoisie hacker community who wants everything to be decentralized", lol. This got really tiresome when I worked on Bitcoin. Lots of semi-technical people who had never run any large system constantly attacking every plausible design of implementable complexity because it wasn't decentralized enough for their tastes, sometimes not even proposing anything better.
• "These [social networks] are not the best people in the history of people, yet somehow, I am supposed to stitch these clowns into a rich cryptographic tapestry that supports key revocation and verifiable audit trails" - another variant of believing decentralized cryptography and PKI is easy.
He also talks about security labels like in SELinux but I never read those papers. I think Mickens used humor to try and get people talking about some of the bad patterns in academic cryptography, but if you want a more serious paper that makes some similar points there's one here:

And for added fun, that same radical decentralization crowd, finally settling on the extremely centralized Lightning crutch, which is not only centralized but also computationally over complicated and buggy.
- ta1243 1y ago> you could enlist a well-known technology company to [run a PKI], If you have a single company, then that's easy enough for a group like Mossad to infiltrate. Probably easier than a distributed system.
- mike_hearn 1y agoThe best known PKI (webtrust) is many companies, not a single company. So it's distributed but that makes it easier to hack not harder because you have many possible targets instead of just one.
- jojobas 1y agoIt is kinda funny, but cost and benefit analysis is not foreign even to Mossad. Mossad would prefer quite a few people's data stolen, but they are not going to carry out a black abroad for most of them.
- commandlinefan 1y ago> going to use a drone to replace your cellphone with a piece of uranium That's assuming they can figure out who you are in the first place. My pipe dream for the internet (that I thought we were getting way back in the 90's) is total anonymity. You can say whatever you like about the mossad, or the NSA or the KGB or whatever you like, and they'll never be able to figure out whose cellphone to replace with a piece of uranium. We have the technology to make it happen (thanks to the paranoid security researchers!) just not the collective will to allow it.
