Unexpected Exposures in the Secure Shell - SSH Security Testing and Research

Explore the evolution and security vulnerabilities of the Secure Shell (SSH) protocol in this 45-minute conference talk from DEF CON 32. Dive into how SSH has grown beyond its initial role as a remote shell service to become a standardized secure transport protocol, second only to TLS in terms of widespread use. Learn about SSH's expansion across various platforms, from POSIX systems to network devices, source code repositories, and Windows-based file transfer tools. Discover insights into lesser-known SSH implementations beyond OpenSSH, including libraries powering numerous applications. Examine critical security issues, exploitation techniques, and get introduced to "sshamble," an open-source tool designed for SSH service security testing and research.
