Exposure management needs a reboot. Great research is the key to innovating new solutions.

Securing your total attack surface has never been more challenging. We believe that applied research is fundamental to building better security solutions to address both new problems and the persistent ones that dog security teams. By sharing our research, tools, and knowledge with our community, we can help each other proactively improve our defenses and raise the bar on attackers.

SSHamble: Exploit SSH protocol vulnerabilities

The runZero research team discovered a range of weaknesses across SSH applications that impact critical network security devices and software. These long standing issues remained undiscovered due to the lack of tooling available – until now!

Read our latest research report: The State of Asset Security

The runZero research team analyzed millions of assets across hundreds of enterprise networks, including internal infrastructure, internet-facing assets, and cloud environments. We found alarming gaps, unexpected trends, and much more.

DEF CON 32: SSHamble: Unexpected Exposures in SSH

The Secure Shell (SSH) has evolved from a remote shell service to a standardized secure transport that is second only to Transport Layer Security (TLS) in terms of exposure and popularity. SSH is no longer just for POSIX operating systems; SSH services can be found in everything from network devices, to source code forges, to Windows-based file transfer tools. While OpenSSH is still the most prominent implementation, it's now just one of dozens, and these include a handful of libraries that drive a wide range of applications.

Watch HD Moore and Rob King talk on stage at DEF CON 32, dig deep into SSH, the lesser-known implementations, many of the surprising security issues found along the way, and how to exploit them.
