Over the years, major IoT botnets like Mirai and Mozi have proven how easily routers can be exploited and threat actors have taken note. Two key issues have played in their favor: the fact that users rarely deploy new firmware to their routers, coupled with the lack of regard for security by router vendors. As a result, router vulnerabilities may persist in the wild for much longer than initially expected, even after patches are published publicly.

In the rapidly evolving world of Kubernetes, network security remains one of the most challenging aspects for organizations. The shift to dynamic containerized environments brings challenges like inter-cluster communication, rapid scaling, and multi-cloud deployments. These challenges, compounded by tool sprawl and fragmented visibility, leave teams grappling with operational inefficiencies, misaligned priorities, and increasing vulnerabilities.

The recently disclosed VMware ESXi vulnerabilities pose a serious security risk, enabling attackers to exploit virtualized environments through VM escape, remote code execution (RCE), privilege escalation, and data leakage. With cybercriminals actively targeting these flaws, organizations must act swiftly to secure their infrastructure.

Financial institutions, such as banks and trading houses, have a strong interest in recording key transaction activity within their networks. In the face of daunting data storage requirements, many are finding that Corelight’s network metadata—notably metadata produced by Zeek—is the key to a simplified tracking and storage process. Many of our customers used to rely on packet capture (PCAP).

The financial industry is known for its rigorous and sometimes quirky data retention requirements that can challenge even the most seasoned security expert. For example, FINRA Rule 4511 requires members to "preserve for a period of at least six years those FINRA books and records for which there is no specified period under the FINRA rules or applicable Exchange Act rules." Keeping six years of records: That's no small feat. But it's certainly doable.

Web application firewalls (WAFs) are one of the most commonly used tools that organizations deploy to protect their applications at runtime. By monitoring HTTP traffic and filtering out suspicious requests, WAFs act as a protective layer around an application that protects it from certain types of incoming threats. However, WAFs often fall short of expectations.

Change is an inevitable part of managing a large-scale enterprise network, but executing it efficiently and securely remains a major challenge. Global organizations must navigate complex IT environments, multiple teams, and a high volume of daily changes—each carrying the risk of misconfiguration, downtime, or security vulnerabilities. Without a structured approach to change management, even routine updates can spiral into costly outages, endless troubleshooting calls, and operational disruptions.

Change isn’t optional—IT leaders know this better than anyone. IT has always been the backbone of the business, keeping everything secure, connected, and efficient. But the demands on IT—and the business—have changed. Cloud adoption, hybrid work, competitive pressures, and rising costs have exposed the cracks in legacy architectures and pushed them past their limits.
