- Review ranges in one operation
- Keep sensitive context in the DM workflow
Setup
Build it in a few focused steps.
- 1Connect Slackbot and Abuselpdb once in the Notis portal.
- 2Create an automation describing how to process network range requests.
- 3Tell Notis to extract a CIDR range from each DM, run Check Block, and summarize the abuse data.
- 4Pick the direct message received trigger and choose where reports go.
- 5Test with one real DM containing a CIDR range.
Questions about this workflow
What happens if the DM has an individual IP?
Ask Notis to use the appropriate instruction for a single address or report that a CIDR range was not found.
Can the report include the requester context?
Yes. Tell Notis to include the relevant DM text in the summary.
