The Fiat-Shamir transform is an important building block in zero-knowledge proofs (ZKPs) and multi-party computation (MPC). It allows zero-knowledge proofs based on interactive protocols to be made non-interactive. Essentially, it turns conversations into documents. This ability is at the core of powerful technologies like SNARKs and STARKs. Useful stuff! But the Fiat-Shamir […]
Trail of Bits is excited to introduce Ruzzy, a coverage-guided fuzzer for pure Ruby code and Ruby C extensions. Fuzzing helps find bugs in software that processes untrusted input. In pure Ruby, these bugs may result in unexpected exceptions that could lead to denial of service, and in Ruby C extensions, they […]
Today, we’re releasing SARIF Explorer, the VSCode extension that we developed to streamline how we triage static analysis results. We make heavy use of static analysis tools during our audits, but the process of triaging them was always a pain. We designed SARIF Explorer to provide an intuitive UI inside VSCode, with […]
Today, we’re releasing weAudit, the collaborative code-reviewing tool that we use during our security audits. With weAudit, we review code more efficiently by taking notes and tracking bugs in a codebase directly inside VSCode, reducing our reliance on external tools, ensuring we never lose track of bugs we find, and enabling us […]
Today, Trail of Bits is publishing Attacknet, a new tool that addresses the limitations of traditional runtime verification tools, built in collaboration with the Ethereum Foundation. Attacknet is intended to augment the EF’s current test methods by subjecting their execution and consensus clients to some of the most challenging network conditions […]
