The Gun Book Club.

Monday, August 14th, 2023

Would you believe I actually got to engage in a little bit of recoil therapy this weekend? Thanks to KR Training for letting us use their range after the class, and thanks to Greg Ellifritz for putting on a great class: “The Explosive Threat: Recognizing, Detecting, and Neutralizing the Terrorist Bomber”.

I didn’t do a lot of shooting because it was hotter than the hinges of Hell, and we didn’t have a lot of time before our dinner engagement. But I did manage to function check a couple of carry guns, and am reasonably satisfied with their performance.

I finished Ammunition, Demystified: The (non) Bubba’s Guide to How Ammo Really Works on my trip. My opinion hasn’t changed. I absolutely do recommend it. But you should be aware that there’s some pretty heavy duty math in the book. I think most folks could probably benefit from it even if times tables give them a headache. My only other issue with the book came when Mr. Siewert discussed some ballistic work he did back in the day with a company that was making air rifle pellets. My issue? “Where were you when I was a teenager, Mr. Siewert?”

And now for some more gun books from the stack…

DEFCON 31 notes, part 3.

There’s a story in The Register about the Johannes Willbold “Houston, We Have a Problem: Analyzing the Security of Low Earth Orbit Satellites” presentation at Black Hat.

But I’m not going to link it. Instead, I’m going to link the Hacker News discussion of the story, which I think is more interesting (and contains a link to the story itself).

There was a suspicious package discovered on Saturday night, and DEFCON was evacuated until it was dealt with. There’s a lot of speculation floating around that I don’t want to link to, so I’m only providing the official statement.

Here’s a really detailed and clear write-up of “A Pain in the NAS: Exploiting Cloud Connectivity to PWN Your NAS”.

And here’s more on “All Cops Are Broadcasting: Breaking TETRA After Decades in the Shadows”, including the team’s paper for the USENIX Security Symposium.

I know I pointed folks to the media server the other day for preliminary presentation slides, but I want to call this presentation out specifically: “Private Keys in Public Places”.
