New tool blocks imposter attacks disguised as safe commands

Tirith is a new open-source, cross-platform tool that hooks into shells (zsh, bash, fish, PowerShell) to analyze pasted commands and block risky patterns—including Unicode homograph URLs, ANSI/bidi/zero‑width injections, pipe‑to‑shell downloads, dotfile hijacking, insecure transport, supply‑chain pitfalls, and credential exposure—performing fast, local analysis without telemetry; it supports Windows, Linux, and macOS via common package managers but does not integrate with Windows cmd.exe.
