WinDiff About WinDiff is an open-source web-based tool that allows browsing and comparing symbol, type and syscall information of Microsoft Windows binaries across different versions of the operating system. The binary database is automatically updated to include information from the latest Windows updates (including Insider Preview). It was inspired by ntdiff and made possible with the help of Winbindex. Screenshot How It Works WinDiff is made of two parts: a CLI tool written in Rust and a web frontend written in TypeScript using the Next.js framework. The CLI tool is used to generate compressed JSON databases out of a configuration file and relies on to find and download the required PEs (and PDBs). Types are reconstructed using . The idea behind the CLI tool is to be able to easily update and regenerate databases as new versions of Windows are released. The CLI tool's code is in the directory. The frontend is used to visualize the data generated by the CLI tool, in a user-friendly way.

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
