## Historique du projet et usages

Terrapin Vulnerability Scanner is the companion command-line scanner for the Terrapin SSH prefix-truncation attack. The official attack site and repository describe it as a small Go console application that tests whether an SSH server or client offers vulnerable encryption modes and whether strict key exchange countermeasures are present.

### Historique du projet

The scanner was published by the Ruhr University Bochum Network and Data Security group alongside the Terrapin research disclosure. Its narrow purpose is deliberate: it gathers SSH algorithm support in a single connection, avoids full authentication, and does not perform the attack.

### Historique d'adoption

Adoption followed the disclosure pattern of a vulnerability-specific operations tool. The project provides release binaries for major desktop platforms, a container image, and Go installation instructions, making it easy for administrators and package maintainers to run quick checks during SSH patch rollouts.

### Modes d'utilisation

The CLI is used either in connect mode against an SSH server or in listen mode for testing an SSH client. It can emit JSON, which makes it useful for scripted fleet checks and package-manager users who want a reproducible local scanner rather than a web-based test.

### Pourquoi les passionnés de paquets s'y intéressent

For package nerds, terrapin-scanner is a compact example of a research artifact becoming a packaged remediation aid. Its Homebrew and Nix packaging matters less as a general-purpose utility and more as a convenient way to reproduce an official scanner during the short operational window after a protocol vulnerability disclosure.

### Chronologie

- 2024: Terrapin paper scheduled for Real World Crypto, Black Hat USA, and USENIX Security presentations.
- 2024: Official scanner released with prebuilt binaries, Docker image, and Go install path.
- 2024: v1.1.3 listed as latest GitHub release on January 18, 2024.

### Related projects

- The scanner is tied to the Terrapin attack research and to SSH implementations that adopted the strict key exchange countermeasure.
