Scanning for HTTP/2 with Rumble
Published on August 15, 2019
This Tuesday, Jonathan Looney, a researcher at Netflix, disclosed seven different ways to break common HTTP/2 protocol implementations, while an eighth issue was disclosed by Piotr Sikora of Google. These issues could be used to exhaust the resources of affected HTTP/2 implementations. Shortly after the HTTP/2 issues were disclosed, a Rumble user reached out asking if we could help identify HTTP/2 endpoints on their network. We are happy to announce that as of version 0.
Hunting for Network Bridges with Rumble
Published on August 5, 2019
Thanks to the wonderful user feedback from Beta 5, a handful of bug fixes and improvements have been deployed along with a new feature: Network Bridge Detection! The bridge report shows external networks in red, internal networks in green, and multihomed assets that bridge these networks in orange. Zooming in will show asset and subnet details, while clicking a node will take you to the asset page for bridge nodes and to a CIDR-based inventory search for network nodes.
Rumble Network Discovery Beta 5
Published on July 30, 2019
Rumble Two Ways with Beta 5 The last few months have been incredible thanks to our wonderful beta community and their vocal feedback. Quite a few folks asked for a version of Rumble they could use independent of the cloud and Beta 5 delivers it. The Rumble Scanner has undergone a makeover and now handles fingerprinting, asset correlation, and rudimentary reporting, making it far more adaptable for restrictive environments and security consulting.
Better TCP Scans Through UDP Discovery
Published on June 11, 2019
One of the trickiest parts of network discovery is balancing thoroughness with speed. We strive to provide a fast, low-impact scan by default, but also try to include as many services and protocols as possible. Today we released version 0.7.5 of the Rumble Agent and Rumble Scanner. This version increases the default port coverage from 100 TCP ports to more than 400, while also supporting discovery and fingerprinting of additional TCP services by leveraging UDP discovery protocols.
Automatic Web Screenshots
Published on May 13, 2019
We rolled out support for automatic web service screenshots this morning in both the Rumble Agent and the Rumble Scanner (v0.6.6+). This option is on by default, and will result in Rumble capturing an image of each web service it encounters if the system it is running on has a working Google Chrome or Chromium installation. This feature can be toggling using the Scanner command line option --screenshots and from the New Scan screen in the Rumble Console:
