Blacklist 📓

Every day our honeypot network processes hundreds of thousands of events. Blacklist 📓 aims to make them more actionable.

While we often partner with projects such as the D4 Project to share our threat information, it is our goal with Blacklist 📓 to make a subset of this information openly available to the public.

Below you'll find the lists we make available as well a short description of each. To avoid decaying of indicators each list is generated several times per day and holds information for malicious activity seen in the last 24 hours (from the time the list is generated).
