Use our suite of Ethereum security tools

Two years ago, when we began taking on blockchain security engagements, there were no tools engineered for the work. No static analyzers, fuzzers, or reverse engineering tools for Ethereum. So, we invested significant time and expertise to create what we needed, adapt what we already had, and refine the work continuously over dozens of audits. […]

"AMD Flaws" Technical Summary

Two weeks ago, we were engaged by CTS Labs as independent consultants at our standard consulting rates to review and confirm the technical accuracy of their preliminary findings. We participated neither in their research nor in their subsequent disclosure process. Our recommendation to CTS was to disclose the vulnerabilities through a CERT. Our review of […]

2017 in review

What a roller coaster of a year! Well, outside of our office. Inside, 2017 was excellent. We published novel research that advanced – among others – the practices of automated bug discovery, symbolic execution, and binary translation. In the process, we improved many foundational tools that an increasing number of security researchers will come to […]

Parity Technologies engages Trail of Bits

We’re helping Parity Technologies secure their Ethereum client. We’ll begin by auditing their codebase, and look forward to publishing results and the knowledge we gained in the future. Parity Technologies combines cryptography, cellular systems, peer-to-peer technology and decentralized consensus to solve the problems that have gone unaddressed by conventional server-client architecture. Their Ethereum client is designed for […]

The Smart Fuzzer Revolution

I recently had the privilege of giving a keynote at BSidesLisbon. I had a great time at the conference, and I’d like to thank Bruno Morisson for inviting me. If you’re into port, this is the conference for you! I recommend that anyone in the area consider attending next year. I felt there was a […]

2016 Year in Review

John Oliver may have written off 2016, but we’re darn proud of all that we accomplished and contributed this year. We released a slew of the security tools that help us -and you- work smarter, and promoted a few more that deserved recognition. We helped the New York City InfoSec community build a foundation for […]

Meet Algo, the VPN that works

I think you’ll agree when I say: there’s no VPN option on the market designed with equal emphasis on security and ease of use. That changes now. Today we’re introducing Algo, a self-hosted personal VPN server designed for ease of deployment and security. Algo automatically deploys an on-demand VPN service in the cloud that is not […]

Come Find Us at O’Reilly Security

We’re putting our money where our mouth is again. In continued support for New York’s growing infosec community we’re excited to sponsor the upcoming O’Reilly Security Conference. We expect to be an outlier there: we’re the only sponsor that offers consulting and custom engineering rather than just off-the-shelf products. We see this conference as an […]

Plug into New York’s Infosec Community

Between the city’s size and the wide spectrum of the security industry, it’s easy to feel lost. Where are ‘your people?’ How can you find talks that interest you? You want to spend your time meeting and networking, not researching your options. So, we put together a directory of all of the infosec gatherings, companies, and […]
