Epic new feature for Recon Safe Utils by @0xJem ! You can finally sign a tx with a Ledger Device and then propose it to your Gnosis Safe!
Most articles on the npm worm did not provide tangible practices or a clear course of action for preventing future attacks. We know because we studied more than 20 articles on the subject 😮💨 Here's our take on what to do, a collab with @alcuadrado 🫡 blog.theredguild.org/how-to-npm-and…
New Free Training: Operational Security for Non-technical Web3 Teams Thursday 2 Oct | 4–5pm CEST | Online Not just devs! BDs, marketers, community managers & execs face cyber threats too. Seats are limited, secure yours now: docs.google.com/forms/d/14TUFp…
Everyone talks about zkVMs. Few talk about the constraint languages that define them. We demonstrated examples with Halo2, Zirgen, and Plonky3 AIR. Not to benchmark, but to show how each expresses computation: hexens.io/blog/zkvm-dsls
Thank you for accepting my application @rektoff_xyz. The next step in cementing my skills to help secure web3. I said it before, but will say it here again. Find something you love to do and it won't feel like work.
Cute little tool to convert hex values to Human Redeable Solidity Interpreted types
Update NOW: Cisco Zero Day SNMP RCE

Huge release for the Recon Extension which can now break invariants with Halmos as well. Same code more power!

Experimenting with an AI automation that can get one of your contracts to 100% of coverage. Looking for feedback and to improve it. Anyone interested in trying it out?
Today's research lead to a deeper understanding, of hardware and Rust handling of reading values in registers. The difference (or similarity) in X86_64 and ARM and registers, and RISC-V calls and implementing opcodes. zkVM compilers,transpilers and elf files. Memory and segments.
Be careful if you use Booking. If you get a sudden invitation to an event where the host pays for all the costs, and it seems too good to be true, be careful. There is some phishing that I haven't fully analyzed yet, but it involves attackers hijacking Booking profiles ⬇️
cohort #2 is loading ⟳ maybe you’re doubting if you should apply maybe you already applied and wonder if it’s worth joining if accepted that’s why we’re running an AMA with your tutors: @m4rio_eth daniel cumming (@rv_inc) lucas (ops guy @rektoff_xyz) -> monday, sept 22 ->…
