Rumble v1.16

Rumble Network Discovery 1.16 is out, helping you find duplicate SSH keys, monitor for rogue remote access solutions, and collect device serial numbers and asset tags.

Finding Duplicate SSH Host Keys

Rumble excels at finding outliers on the network, and finding duplicate SSH keys is one application of this. Vulnerability scanners can find a known bad SSH keys but they don’t look for duplicate keys. Rumble collects all SSH key MD5 hashes and then pivots over the SSH host key MD5 to find keys that exist more than once.

Monitoring for Remote Access Solutions

Remote Desktop Protocol (RDP) is a useful tool when enabled on a machine that’s properly managed on the domain (that is if you’re properly managing local accounts). However, RDP can also put you at risk if active on a machine that’s not in your domain. It’s typically tough to find those, but with Rumble you can. Rumble now detects the TeamViewer protocol on your network in addition to the existing coverage for RDP, VNC, SPICE, and PC Anywhere. This rounds off Rumble’s broad support for monitoring remote access solutions.

Collecting Device Serial Numbers and Asset Tags

A few weeks ago, one of our customers asked us if we could pull serial numbers out of Cisco devices because this would be very useful for their MSSP business, and it’s now included in Rumble. Pulling serial numbers remotely can be very useful to for support questions and to see if a device’s warranty has expired and it should be replaced. You must have SNMP credentials (or the v2 community “public”) configured for your scans for this query to work.
