Review network blocks from Slack
Assess the broader picture when a teammate shares a CIDR range for investigation, without manually opening another tool.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Check Block
Tool to check the reputation of all ip addresses in a cidr range. use when you need aggregated abuse data for a network block.
Why this helps
A single suspicious address can point to a wider issue, but range checks often get postponed while people switch tools.
- Checks a CIDR range's aggregated abuse data.
- Makes range-level review part of the Slack conversation.
- Reduces friction when assessing a possible wider incident.
Setup
Build it in a few focused steps.
- 1Connect Slack and Abuselpdb to Notis once in the portal.
- 2Create an automation in the portal or ask Notis conversationally.
- 3Give Notis one instruction to find a CIDR range in a Slack message, check it in Abuselpdb, and report the aggregate result.
- 4Select Slack Channel Message Received as the trigger and pick a run-report channel.
- 5Test with a real Slack message that includes a CIDR range.
