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.
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. We were able to update the scan engine quick and this feature is now included as of release 1.15.3. 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.
