OpenSSH Research Uncovers Key Cyber Defense Insights from the Perspective of 2025's Pwnie Awards
In the rapidly evolving landscape of cybersecurity, Qualys' Threat Research Unit (TRU) has once again made headlines with their groundbreaking work on OpenSSH. The team's recent discoveries have uncovered critical vulnerabilities, including CVE-2024-6387, a pre-auth Remote Code Execution (RCE) issue in the OpenSSH server's default configuration on glibc-based Linux systems. This reintroduction of a 2006 bug has raised concerns among security professionals worldwide.
Qualys' CEO, Sumedh Thakar, is proud of the company's contribution to the security community. The company's research, such as the multi-year work on OpenSSH that led to the discovery of CVE-2025-26466, strengthens the security community through responsible disclosure.
The importance of this research is underscored by the fact that these vulnerabilities affect millions of devices worldwide, including servers and Internet of Things (IoT) devices. Rapid patches were issued by OpenSSH maintainers following Qualys TRU's discoveries, highlighting the urgency of addressing such issues.
Qualys' TRU team has been recognised for their work, winning two awards this year at the Pwnie Awards, held at Black Hat and DEF CON. They were awarded Best RCE for regreSSHion (CVE-2024-6387) and Epic Achievement for their work on OpenSSH.
In the fast-paced world of 2025, with exploits being weaponized in hours, automating detection and patching is essential for survival. Qualys' TRU aims to reduce the number of stragglers at 30/90 days with their auto-staging patches for the highest-risk sets.
Qualys' TruRisk prioritizes vulnerabilities by real-world exploitability and exposure, helping security teams stay ahead of evolving risks. By ranking assets by risk-to-business, not CVE noise, Qualys' customers can focus on the most critical issues.
Subscribing to Qualys' blog keeps users informed of the latest TRU posts, ensuring they are always up-to-date with the latest discoveries and recommendations. Qualys' TruRisk also measures Mean Time to Repair (MTTR) on a live survival curve, providing valuable insights into the effectiveness of patching efforts.
The first 24 hours are crucial for patching critical vulnerabilities, with half of the fixes being implemented during this time. With Qualys' TruRisk, security teams can stay ahead of the curve in 2025 and beyond, ensuring their systems remain secure in the face of ever-evolving threats.
