Overview

The SSL Blacklist (SSLBL) is a project of abuse.ch with the goal of detecting malicious SSL connections, by identifying and blacklisting SSL certificates used by botnet C&C servers.
For more information, visit: https://sslbl.abuse.ch/

Use the abuse.ch SSL Blacklist feed integration to fetch indicators from the feed.

Configure abuse.ch SSL Blacklist Feed on Cortex XSOAR

Create a required Auth Key for abuse.ch

Note: If you already have a profile, you can skip steps 1 and 2.

Sign up for an abuse.ch account. You can do this easily by using an existing account that you may already have on X, LinkedIn, Google or Github. Just log in with the authentication provider of your choice here: https://auth.abuse.ch/
Once you are authenticated on abuse.ch, ensure that you connect at least one additional authentication provider. This will ensure that you have access to abuse.ch platforms, even if one of the authentication providers you use shuts down (yes, it happened with Twitter!)
Ensure that you hit the “Save profile” button. In the “Optional” section, you can now generate an “Auth-Key”. This is your personal Auth-Key that you can now use in the integration.

Configure Cortex XSOAR

- Auth Key: Enter the Auth-Key generated from your abuse.ch profile.

- Fetch indicators: boolean flag. If set to true will fetch indicators.
- Fetch Interval: Interval of the fetches.
- Source Reliability: Reliability of the feed.
- Traffic Light Protocol Color: The Traffic Light Protocol (TLP) designation to apply to indicators fetched from the feed. More information about the protocol can be found at https://us-cert.cisa.gov/tlp
- Skip Exclusion List: When selected, the exclusion list is ignored for indicators from
  this feed. This means that if an indicator from this feed is on the exclusion
  list, the indicator might still be added to the system.

  reputation.
