Feel free to contribute.
Most of the resources listed below provide lists and/or APIs to obtain (hopefully) up-to-date information with regards to threats. Some consider these sources as threat intelligence, opinions differ however. A certain amount of (domain- or business-specific) analysis is necessary to create true threat intelligence.
| AutoShun | A public service offering at most 2000 malicious IPs and some more resources. |
| Critical Stack Intel | The free threat intelligence parsed and aggregated by Critical Stack is ready for use in any Bro production system. You can specify which feeds you trust and want to ingest. |
