Grey Noise Trends Overview with Nick Roy
Summary: GreyNoise Trends lets security teams query hosts tagged with activity such as a CGI script scanner classified as malicious in the last day, then drill into a tag to see time series data on the number of IPs observed over the last 3, 10, or 30 days. For vulnerability tags such as Log4j, the feature also shows related CVEs, published references, and timelines for when GreyNoise created the tag and when the CVEs were republished, alongside a block list or EDL available by URL and a downloadable list of observed IPs.
What you should know: The block list is pitched at buying time during initial triage of a new vulnerability, when alert volume from internet-wide scanning is highest and analysts have not yet sorted real compromises from background noise.
