Wasting less time on twitter has always been a goal, but it looks like the universe is helping me with that.

This account isn't going anywhere, but i'll be checking in on it less and less.

Yay! My first ULX5M blinky!

I don't have any 1 mm pins for JTAG, and no bootloader yet for this @colognechip GateMate FPGA, so it's also spider jig day!

Tigard JTAG board continues to be awesome.

CanSecWest is only a few weeks away.

I don't run my Hardware Implants class very often, and rarely outside the USA, so if you want to take it, this might be your last chance for at least a year.

If you're considering it but haven't registered yet, let us know asap!

The next opportunity to master TEE exploitation is with our upcoming TEEPwn training at CanSecWest 2026 (September 26-29 in Vancouver):

Happy to share that #TEEPwn is back!

We will be touching upon those software/hardware boundaries that make TEE exploitation unique.

See you in Canada!

Thanks for the lab @securelyfitz

Only a couple weeks until @CODEGATE_KR - there's still time to register for training. I'll be offering a special 3-day version of Applied Physical Attacks on Embedded & IoT systems, with some added topics from my Hardware Penetesting course. See you there!

Okay - my last post on this for a while:
*Today* is the last day for early registration discounts at @BlackHatEvents USA!

I've got a few courses on both attacking and defending embedded devices. Check them out:

Today's daily @BlackHatEvents USA training reminder comes to you in rant form:

AI is definitely a thing. Fundamentally, it is a tool that may or may not improve your work with trade-offs that may or may not be worth it.

So - No, my classes do not incorporate AI. Yes, you can 'solve' the labs in my classes faster with some AI assistance. But no, you cannot understand the "why" of the labs in my class if you do.

End rant, begin shameless plug:

Black Hat early registration discounts end tomorrow, and there are a ton of excellent classes available, including my own:
