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.

Jump down the security rabbit hole with us every month as our research team unpacks risky exposures, attack surface anomalies, and the most random vulnerabilities lurking in your IT, OT, IoT, remote, cloud, and mobile environments.
Join our Founder and CEO, HD Moore, as he delivers the keynote at SnowFROC! He’ll share insights on building lasting security tools, open-source projects, and communities—making this a must-attend event in the heart of the Rockies.
Larry Wall said great programmers embody laziness, impatience, and hubris—traits that drive innovation but fragment security tools. Drawing from Metasploit and his latest projects, HD will share how to build for longevity and create tools that outlive their creators.
Don’t miss this deep dive into security innovation—see you in Denver!
Tune in as HD Moore joins the Next-Gen SecOps panel to discuss the evolution of security operations with cloud services, automation, and decentralized teams.
Learn how new tools enhance threat detection, streamline operations, and improve visibility across a growing attack surface. The panel will also explore how to build a modern SecOps team, select the right technologies, and maintain clear visibility into cloud and enterprise assets.
Don’t miss this essential conversation!
Join our Founder and CEO, HD Moore, in San Francisco as he charts the SSH multiverse! SSH—second only to HTTP in internet-wide exposure—has had a rocky year, and this talk dives into its many implementations, weaknesses, and real-world exposures.
Plus, don’t miss Rob King, Director of Security Research, as he explores the security implications of IT and OT convergence. His talk will cover OT protocols, device discovery, and navigating security challenges—even behind legacy protocol gateways.

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. |

We are a group of industry veterans with decades of experience in information security, who are committed to runZero’s foundational principle that applied research makes for better asset discovery, and that better asset discovery is the foundation of modern exposure management.
The goal of the runZero research team is to discover incredibly efficient ways to pinpoint at-risk devices and quickly get this information into the hands of our customers and community. We achieve this through both precise fingerprinting and fast outlier analysis across IT, OT, IoT, cloud, mobile, and remote environments.Â
