We’re thrilled to announce that Trail of Bits will be competing in DARPA’s upcoming AI Cyber Challenge (AIxCC)! DARPA is challenging competitors to develop novel, fully automated AI-driven systems capable of securing the critical software that underpins the modern world. We’ve formed a team of world class software security and AI/ML experts, bringing together researchers, […]
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 […]
Last month our Cyber Reasoning System (CRS) -developed for DARPA’s Cyber Grand Challenge– audited a much larger amount of code in less time, in greater detail, and at a lower cost than a human could. Our CRS audited zlib for the Mozilla Secure Open Source (SOS) Fund. To our knowledge, this is the first instance […]
Finding bugs in programs is hard. Automating the process is even harder. We tackled the harder problem and produced two production-quality bug-finding systems: GRR, a high-throughput fuzzer, and PySymEmu (PSE), a binary symbolic executor with support for concrete inputs. From afar, fuzzing is a dumb, brute-force method that works surprisingly well, and symbolic execution is […]
No doubt, DARPA’s Cyber Grand Challenge (CGC) will go down in history for advancing the state of the art in a variety of fields: symbolic execution, binary translation, and dynamic instrumentation, to name a few. But there is one contribution that we believe has been overlooked so far, and that may prove to be the […]
At the end of last year, we had some free time to explore new and interesting uses of the automated bug-finding technology we developed for the DARPA Cyber Grand Challenge. While the rest of the competitors are quietly preparing for the CGC Final Event, we can entertain you with tales of running our bug-finding tools […]
The Cyber Grand Challenge qualifying event was held on June 3rd, at exactly noon Eastern time. At that instant, our Cyber Reasoning System (CRS) was given 131 purposely built insecure programs. During the following 24 hour period, our CRS was able to identify vulnerabilities in 65 of those programs and rewrite 94 of them to […]
We are proud to have one of the only seven accepted funded-track proposals to DARPA’s Cyber Grand Challenge. Computer security experts from academia, industry and the larger security community have organized themselves into more than 30 teams to compete in DARPA’s Cyber Grand Challenge —- a first-of-its-kind tournament designed to speed the development of automated security […]
