@twomikecharlie I haven't used WinDbg TTD in a remote setup, so idk if that works. With esReverse (formerly REVEN) you can do full-system TTD with Windows targets:

@sadarex @GossiTheDog Ummm OK, so a newly created dept can take away money from DHS bypassing congress/senate/president? And this is constitutional? o.O

@twomikecharlie On Windows I'd just use WinDbg's TTD (or REVEN).

@GossiTheDog Excuse my EU ignorance, but what authority does DOGE have over random agencies HR decisions?

Fun fact: you can attach to the gdbserver exposed by #rr and do #TimeTravelDebugging from #Ghidra :)

UX is similar to ret-sync.

, 8 Apr 1959, Mary K Hawes initiates a project to create the first universal programming language for computers used by businesses and government. Grace Hopper led the team that then created COBOL. Some mainframes are still using it.

Spring has sprung. Birds are singing, flower buds are budding and the website is open for business. Bookmark https://defcon.org/html/defcon-33/dc-33-index.html for all the latest info on everything . August will be here before you know it and you’ll want to be in the loop as things develop.

Stay in touch, and we’ll see you at .

Apparently Bugcrowd was not pwned, they just try to roll out mandatory MFA:

https://www.bugcrowd.com/blog/bugcrowd-security-update-password-reset-and-mfa-requirement/

Scientists still struggle to come up with a way how this information could be included in the password reset mails they sent out, we’ll keep you updated about any breakthroughs!

Interesting talk on designing low-bit floating point number systems. Imagine you have 6-bits, using IEEE754 would you want to waste 6 of your codes for different NaNs? Do you really need two zeros? How about adding ±∞ or does saturating to ±FLT_MAX work for you use case? You can upconvert to Binary32 or Binary64 to do math operations, but which one gives you the better conversion when re-packing back down to 6-bits?

IEEE working group P3109 has the goods.

Here is another challenge. While I know what the device does, I was not able to identify much of the components on the circuit board. Quite sure I could not solve this challenge myself.

So far I have not been able to identify
* the microcontroller
* the silver can on the top right
* any datecode

As always, please write down your deductions and guesses behind a CW to not spoil it for others.

At @recon , @nicolodev and I discuss the current state of MBA (de)obfuscation and their applications. We’ll also introduce a new plugin for simplifying MBAs in the decompiler.

Details: https://cfp.recon.cx/recon-2025/featured/

I'll also give a training: https://recon.cx/2025/trainingSoftwareDeobfuscationTechniques.html
