@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).

@twomikecharlie This is still Linux, I'm debugging loadlibrary: https://github.com/taviso/loadlibrary/

@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.

#OnThisDay, 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 #DEFCON33 website is open for business. Bookmark https://defcon.org/html/defcon-33/dc-33-index.html for all the latest info on everything #DC33. 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 #defcon.

@mdfranz Gitea is great!

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

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!

@raptor Ugh, that's some terrible communication, thanks for the info!

[RSS] 'ToddyCat' Hackers Exploit ESET Antivirus Flaw to Bypass Windows Security

Spoiler: version.dll strikes again...

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.

So Bugcrowd got pwned or what?

OH: it's a nice conditional jump you have here. it would be a shame if something happened to it

Here is another #NameThatWare 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 #BinaryNinja 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

@dey My educated guess is the bank didn't even get the request from the gov system...

• Welcome to the #Bureaucracy! You owe us some money, but fear not, you can easily pay it with our very modern VPOS!
• Really? There’s no new items in my online mailbox you usually use.
• Oh we sent this request in a (non-certified) paper letter to the other side of the city.
• commuting Got the letter, what’s the URL for the VPOS?
• Oh we won’t tell you that…
• Nvm, I just googled it, what’s next?
• You have to choose the code that corresponds to your debt!
• Is the code in the letter you sent me?
• No, but we gave each code a title, multiple of which are very similar to what you want to pay for.
• googling OK, I found a page that matches the codes with account numbers and you did sent me the an account number so I think I found the right code!
• (mumbbling Damn it we have to get that page down!)
• So you actually sent me two letters with different sums, which one is correct?
• crickets
• I’ll just pay the bigger amount, just in case click pay Transaction rejected!
• Banks these days, huh?
• Let’s retry…
• You can’t just retry, the form you filled out is invalid now! But we can automatically create you a copy.
• This “copy” has a NULL where the original had some unique ID, are you sure this is right?
• We’re sure it’s fine…
• Alright, click pay
• UNRECOVERABLE ERROR
