The SSH protocol turned out to be less secure than previously thought.
The company RunZero, known for its solutions in the field of cybersecurity, introduced a new tool called SSHamble, which is designed to check the implementation of the SSH protocol for vulnerabilities and configuration errors. SSH (Secure Shell) is used everywhere-from network devices and servers to applications and tools for data transfer. However, despite the popularity of OpenSSH, there are many other implementations of this protocol, and each of them can have its own unique problems.
During the study, RunZero specialists found a significant number of vulnerabilities in various SSH implementations that can lead to critical security breaches. Many of these problems went unnoticed due to the lack of tools for deep testing of all layers of the SSH protocol.
SSHamble was created to fill this gap. This tool allows you to simulate potential attacks and scenarios such as unauthorized remote access, execution of commands after the session ends, and information leakage through unsupervised authentication requests. SSHamble provides an interactive shell that allows access to SSH requests in a post-session environment, making it easier to test various security aspects, such as environment management, signal handling, and port forwarding.
