Listening to the internet allows GreyNoise to uncover unique behaviors and TTPs. We capture vulnerability lifecycles with our tags to show when scanners are looking for opportunities to exploit recently announced vulnerabilities. For example, when the F5 vulnerability was announced, our team quickly created tags to identify IPs scanning for targets to exploit. Teams can also dynamically research our data using GNQL, the GreyNoise query language.
Another common example is when a new CVE is released, that CVE can be queried each day to see the total number of IPs that are scanning for it, so a team can assist how critical of a threat this is to their organization and if a "break-the-glass" protocol should be enacted.
An analyst uses the GreyNoise Visualizer to monitor trends being tracked within GreyNoise and can also do advances queries for the Visualizer and CLI to aid in Threat Hunting or Incident Response.
