Rumble Network Discovery Beta 1 Highlights

Now that the first beta release of Rumble Network Discovery is available for testing, we wanted to highlight some of the things that the product does differently.

Command-Line Scanner & Offline Support

This release allows basic inventory to be completed using either an installed agent or the command-line scanner. Both the agent and the scanner consist of a single executable with no external dependencies. The command-line scanner can be used in offline environments and for work that is security sensitive, where uploading data back to the cloud isn’t an option.

Ridiculously Fast

A typical /24 network can be scanned scanned in less than 30 seconds. Rumble does this using a scanning engine built from scratch with exactly one purpose in mind. Careful selection of probes and port types enables Rumble to gather detailed information across the network almost instantly. Rumble can be tuned down for slower environments and ramped up to cover huge networks quickly. Sprawling, complex, and highly segmented networks are what Rumble was built for.

Multi-Homed Asset Identification

Rumble uses a handful of techniques to identify additional network interfaces across scanned assets, without credentials or access to a span port. This allows for detection of security pivot points and better recognition of misconfigured and otherwise exposed hosts. Rumble scans can identify systems that are connected through a VPN, running virtualization software, and bridging network segments.

Almost-Magic MAC Address Detection

Rumble can obtain MAC addresses from devices outside of the local network, without credentials, across a wide range of systems. This detection is combined with our research into MAC fingerprinting and age detection to provide insights into systems that are difficult to obtain otherwise.

Names, Domains, and Hostnames

Rumble tries to pull system names out of a multitude of services. This allows inventories to show not just the NetBIOS or reverse DNS name for an asset, but also a list of any web sites being hosted, and often additional information about a device, such as the service tag or serial number. Domain names are automatically obtained from a number of services and by parsing out identified hostnames.

Continuous Research

Rumble was created with the goal of building the best network discovery platform through continuous research. The highlights above cover some of the work that has been done so far, but we have still have a long way to go. You can hear details of some of our discovery techniques at the upcoming InfoSec Southwest 2019 security conference in Austin, Texas. In the meantime, kick the tires on the beta and let us know what we got wrong (or right!).
