Check flagged IPs with a Slack reaction
Let a simple reaction signal that an IP needs a reputation check, so the next step is clear without adding another message.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Check IP Reputation
Tool to check the reputation of an ip address. use when you need to determine if an ip address has been reported for abusive activity within a specified look-back period. example: checkip(ipaddress='8.8.8.8', maxageindays=90).
Why this helps
Security follow-ups can get buried when people discuss a suspicious address but nobody clearly owns the lookup.
- Creates a lightweight review cue inside Slack.
- Checks only when a teammate marks a message for review.
- Avoids a separate handoff just to request a lookup.
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 to set it up conversationally.
- 3Write one instruction asking Notis to check the IP in a reacted-to Slack message and summarize its reputation.
- 4Select Message Reaction Added, choose the reaction trigger, and select a channel for run reports.
- 5Test by adding the chosen reaction to a real message with an IP.
