Runzero, a cybersecurity solutions provider, has recently launched a new tool called shamble aimed at assessing the implementation of the SSH protocol for vulnerabilities and configuration errors. SSH (Secure Shell) is widely utilized in network devices, servers, applications, and data transmission tools. Despite the predominance of OpenSSH, there are numerous other implementations of the protocol, each potentially harboring its own unique issues.
Runzero’s experts conducted a study and identified a significant number of vulnerabilities across various SSH implementations, posing serious security risks. Many of these vulnerabilities went undetected due to the absence of comprehensive testing tools that can assess all layers of the SSH protocol.
Sshamble was developed to address this gap in security testing. This tool enables users to simulate potential attacks and scenarios, such as unauthorized remote access, post-session commands, and information leakage through uncontrolled authentication requests. SSHAMBLE offers an interactive shell for accessing SSH in a post-session setting, facilitating testing of security aspects like environment management, signal processing, and porting ports.
