The Secret Life of Circuits

Electronic circuit design, drawn by hand and explained from first principles.

Well, I think my mail server is stable again. There was a bit of a scare, but no actual damage from hackers. It did force me to make some changes to my firewall filtering, and my Postfix client access rules.

The tricky bit was to reject clients without a proper rDNS record, but not reject my phone, which the cell network does not support rDNS on.

But Postfix already figured this out. So now my phone is trusted, but the skiddies are blocked more effectively than before.

I've met Steve, and was impressed with how friendly and down-to-earth he was. The kind of guy you'd like to meet for beers on Friday, to unwind the week.

Here he is, talking to new graduates about AI. And reminding them that their brains are still better than any machine. And that they should aim at doing things in a way that's *different* from what "everyone else" is doing.

Today, I found a hacker trying to log in to my IMAP server using one of my (real) passwords as the username. That made my heart skip a beat. I eventually tracked it down to the Internet Archive breach in 2024.

But it was the impetus to make me finally lock down port 993 to just my known IP sources. So that was useful.

I suspect I've pissed of people in China and Bulgaria now...

Sometimes I talk about things that are not cybersecurity or human rights. On June 2nd, come hear me talk about the Opium Wars--that time the British Empire fought the war on drugs, on the side of drugs.

DEF CON 3d ago

DEF CON 34 is an electronic badge year, and we’ve got something very special in store, created for us by a hardware hacking legend. We can’t share too much at this juncture, but we can say this: it will be iconic. First round Hall of Fame. In addition to being a cool badge, it’s a platform. It’s a full-fledged, first-of-its-kind inspectable platform. Long after closing ceremonies we think you’ll still be using this device to regain some agency and security in this rapidly complexifying world.

So what we can offer right now is some data to help all the SAO enthusiasts out there. Please enjoy this spec sheet with the relevant schematics, measurements and clearances for your projects. Electro-specs also included.

We’re excited to see what you come up with. As good as the badge is, we know you can make it better.
