Network Discovery Powered by Research
Published on November 12, 2019
Refocusing on Research Our mission is to empower our customers with amazing network visibility through applied research. With the v1.1.0 release behind us, we are excited to renew our focus on research. Last month, our founder and CEO HD Moore presented at Texas Cyber Summit and LASCON X on modern network discovery techniques. This post highlights three techniques from this presentation and how Rumble uses them to improve network visibility.
DNS Ping Scans via Open Resolvers
Published on April 2, 2019

Our last post covered some of the ways that Rumble gathers information from DNS services. While working on the tracer implementation, we identified a trick that other folks might find it useful. It turns out that most DNS resolvers do not filter the address ranges they will contact when handling a request, allowing for remote subnet “ping scans” with a little work. This technique isn’t foolproof, and is probably not new, but it may have interesting security implications.
