@zeifan Hardware hacking time!

https://t.co/vZbAGrKphv something Claude help with over the weekend :)

⏰ LAST DAYS: Proxmark5 at its lowest price EVER.

We're inches from unlocking the transparent case for EVERY backer.

This is the most powerful RFID research tool yet future-proof and ready for the next decade.

Who’s jumping in before it ends?

[Iceman @herrmann1001]

$808k+ raised with over 2380 backers on Proxmark5 - thank you!

We're pushing hard for the $1M Transparent Casing stretch goal in the final week.

Only 7 days left at early pricing.

What do you think, should we go for it?

[Earl Marcus @klks84]

@nadiahlotfi i've seen them being sold on taobao for cheap, have you tried sourcing there?

The real reward I experienced from organising @CybercampMY is when seeing those alumni who trusted my approach achieved their goals. Added with compliments from the managers/bosses of the other companies who impressed with them.

Time to conclude another experiment. It was fun.

Anthropic just open-sourced a reference framework for AI-powered vulnerability discovery and remediation 🤖💀

The workflow:

Recon → Find → Verify → Triage → Report → Patch

Features:
• Threat modeling
• Autonomous vulnerability hunting
• Crash verification
• Finding deduplication
• Exploitability analysis
• AI-generated patches with validation

Built around Claude Code and sandboxed agents using gVisor.

Interesting signal: AI is moving beyond code generation into autonomous security research and vulnerability management.

Proxmark3 RDV4.01 vs Proxmark5 side-by-side operation.
- HF SEARCH
- HF MF INFO

The larger FPGA with no image swapping is noticeable faster.

AD CTF 2.0 is a wrap!

We have finally returned to our schedule with another exciting session alongside Range Village. We’re incredibly happy to see all of you joining this Active Directory-focused CTF challenge.

[Iceman @herrmann1001]

$730k+ raised on Proxmark5 with 2150 backers

Thank you!

We're getting close to the $1M Transparent Casing stretch goal.
What would you like to see unlocked next?

Themida turns a few lines of code into thousands of VM handler instructions. Completely unreadable.

back engineering built a static devirtualizer that lifts it all to IR, resolves the control flow, and recovers the original logic.

The before/after in the repo is genuinely shocking.

Works on pretty much any VM obfuscator, not just Themida.

Chat, I don't want to be that guy, but I think Microsoft has really pissed off security researchers and we're approaching the tipping point.

This Eclipse guy has really rocked the boat for Microsoft.

MSRC: Either you let us bully you and treat you like garbage or we’ll send you to jail

[Andrew Case @attrc]

MSRC woke up and decided to kill off all the good will it has built up over the last decade:

[Adam Chester 🏴‍☠️ @_xpn_]

Remember, these companies are trillion $$$ empires, relying on the goodwill and patience of hackers for too long. MSRC has forced many of us to turn our back on responsible disclosure and proven that the only meaningful method of change is via full-disclosure. As @0xcharlie once said so well... NO MORE FREE BUGS!

[nafiez @zeifan]

Found a denial-of-service vulnerability in a Windows driver (a classical IOCTL bug) that can trigger a BSOD. Reported to the vendor; no patch is planned. Sharing here the writeup (I asked AI to write one for me). Enjoy🫰

I know it is really hard to understand how much better and improved the proxmark3 has become over the years.

Here is a graphic list of the following card technologies that is currently supported in #proxmark.

[Iceman @herrmann1001]

We just unlocked the $600k Transparent PCB Name card stretch goal!

This one means a lot. Thank you from the bottom of my heart!

not just for the funding, but for believing in the vision of a proper next-generation open source RFID research platform.

The Transparent PCB Name card will be something really special.

19 days left to go, what should we aim for next?
