项目说明

Terrapin Scanner

The Terrapin Scanner is a small utility program written in Go, which can be used to determine the of an SSH client or ser the Terrapin Attack. The scanner requires a single connection with the peer to gather all supported algorithms. However, it does not perform a fully fledged SSH key exchange, will ne authentication on a server, and does not perform the attack in practice. Instead, is determined by checking the supported algorithms and support for known countermeasures (strict key exchange). This may falsely claim in case the peer supports countermeasures unknown to this tool.

Running

For con, we are pro pre-compiled binaries for all major desktop platforms. These can be found on the Release page. We have also provided a Docker image that supports most of the major architectures. This image can be run as:

> [!IMPORTANT]
> Note that when running the Terrapin Scanner inside a Docker container, the tool will bind to the container's localhost when specifying --listen with port only. To avoid connectivity issues, add 0.0.0.0 as its bind address and map the container's port to the host 's -p argument.

> The following command will make the Terrapin Scanner a at port 2222 on the host system's localhost:

Building

However, we understand that you might prefer building tools that connect to your SSH ser. To do this, ensure that you have at least Go v1.18 installed. To compile and install the Terrapin Scanner Go package, run the command below.

This will download, compile, and install the Go package for your local system. The compiled binary will become a at $GOBIN/Terrapin-Scanner. If the GOBIN en is not set, Go will default to using $GOPATH/bin or $HOME/go/bin, depending on whether the $GOPATH en is set.

You can also build the Docker image yourself by running the commands below.

Usage

The scanner supports outputting the scan result as json. To do so, provide the --json flag when calling the scanner. The output is structured as follows:
