MISP / misp-feedback

Public

A high-performance warninglist lookup engine that checks indicators of compromise (IOCs) against MISP warninglists. It identifies false positives by matching values against 120+ curated lists of known-good infrastructure: cloud provider IP ranges, top domain rankings, public DNS resolvers, certificate authorities, and more.

AI Summary

MISP Feedback is a high-performance tool for checking indicators of compromise against MISP warninglists to identify false positives from known-good infrastructure.

How It Works

1
🔍 Discover MISP Feedback

You hear about a handy tool that quickly checks suspicious web addresses, IP numbers, or emails against trusted lists of safe places to spot false alarms.

2
📥 Get it ready

You download the program and set it up on your computer so it's ready to use.

3
📁 Prepare trusted lists

You point it to a folder of curated lists that know which cloud services, popular sites, and helpers are actually safe.

4
🚀 Start the background helper

With one simple command, you launch a quiet background service that loads everything into memory for super-fast checks.

5
✅ Check your suspects

You type in an IP like 8.8.8.8 or a domain like google.com, and it tells you right away if it matches any safe lists.

🎉 Spot false positives instantly

You now easily filter out common safe items from your alerts, saving time and reducing noise in your security work.

What is misp-feedback?

MISP Feedback is a Rust daemon that checks indicators of compromise against 120+ curated MISP warninglists, flagging false positives like cloud provider IP ranges, top domain rankings, public DNS resolvers, and certificate authorities. It loads lists into memory for sub-millisecond lookups over Unix sockets or HTTP, with a CLI for batch checks from files or pipes, and a simple web UI for quick queries. Run it as `misp-fbd` for the server and `misp-fb check` for CLI access to endpoints like `/lookup` or `/lookup/batch`.

Why is it gaining traction?

In a world of high performance GitHub tools chasing C++ high performance GitHub benchmarks or high performance Python GitHub scripts, this Rust engine delivers 1.4M lookups/sec on 2.5M entries without the hassle—auto-reloading lists on changes, JSON/CSV output, and seamless Unix pipeline integration like grepping logs into `misp-fb check`. Devs love the zero-config HTTP API with Swagger docs and false-positives-only filtering, cutting noise in IOC feeds instantly.

Who should use this?

SecOps teams validating MISP events or Zeek logs against known-good infra, SIEM analysts batch-filtering domains and IPs from threat intel, or backend devs enriching IOCs in high performance backend GitHub pipelines before alerting. Perfect for anyone tired of manual false positive hunts in compromise detection.

Verdict

Grab it if you need fast, local warninglist checks—docs are thorough, perf is legit, and Rust ensures reliability. With 10 stars and 1.0% credibility score, it's early but battle-ready for prod; test on your workload before scaling.
