A retrospective on the $100M Balancer hack that occurred in November 2025, including long-term, strategic guidance on how to avoid similar bugs.

This blog post describes how electronic passports work, the threats within their threat model, and how they protect against those threats using cryptography. It also discusses the implications of using electronic passports for novel applications, such as zero-knowledge identity proofs.

Trail of Bits is disclosing vulnerabilities in confidential computing systems that use LUKS2 for disk encryption. These vulnerabilities allow attackers with access to storage disks to extract confidential data and modify contents.

We bypassed human approval protections for system command execution in AI agents, achieving RCE in three agent platforms.

We created a CodeQL query that reduced 2,500+ compiler warnings about implicit conversions in OpenVPN2 to just 20 high-priority cases, demonstrating how to effectively identify potentially dangerous type conversions in C code.

Supply chain attacks exploit fundamental trust assumptions in modern software development, from typosquatting to compromised build pipelines, while new defensive tools are emerging to make these trust relationships explicit and verifiable.

Mutation testing reveals blind spots in test suites by systematically introducing bugs and checking if tests catch them. Blockchain developers should use mutation testing to measure the effectiveness of their test suites and find bugs that traditional testing can miss.

We’ve added a pickle file scanner to Fickling that uses an allowlist approach to protect AI/ML environments from malicious pickle files that could compromise models or infrastructure.

Sui’s Move language significantly improves flash loan security by replacing Solidity’s reliance on callbacks and runtime checks with a “hot potato” model that enforces repayment at the language level. This shift makes flash loan security a language guarantee rather than a developer responsibility.

By using smart contract programmability, exchanges can build custody solutions that remain secure even when multisig keys are compromised.

A vulnerability in Electron applications allows attackers to bypass code integrity checks by tampering with V8 heap snapshot files, enabling local backdoors in applications like Signal, 1Password, and Slack.

Our business operations intern at Trail of Bits built two AI-powered tools that became permanent company resources—a podcast workflow that saves 1,250 hours annually and a Slack exporter that enables efficient knowledge retrieval across the organization.

EIP-7730 enables hardware wallets to decode transactions into human-readable formats, eliminating blind signing vulnerabilities with minimal implementation effort for dApp developers.

We optimized the route for visiting every NYC subway station using algorithms from combinatorial optimization, creating a 20-hour tour that beats the existing world record by 45 minutes.

In this blog post, we’ll detail how attackers can exploit image scaling on Gemini CLI, Vertex AI Studio, Gemini’s web and API interfaces, Google Assistant, Genspark, and other production AI systems. We’ll also explain how to mitigate and defend against these attacks, and we’ll introduce Anamorpher, our open-source tool that lets you explore and generate these crafted images.
