- Summary: Slack is a business communication platform. It offers chat rooms in the form of channels organized by topics as well as private groups and direct messaging. Users can create Slack applications to automate some actions in workspaces. This detector focuses on catching Slack signing secrets. Those secrets are used by Slack applications in order to authenticate requests coming from Slack.
- IPs allowlist: This feature is not supported.
- Scopes: All keys have the same permission, and allow to authenticate Slack requests.
