# MISP warninglists
MISP warninglists are lists of well-known indicators that can be associated to potential false positives, errors or mistakes.
There is a Python module available to work with warninglists in a Pythonic way called [PyMISPWarningLists](https://github.com/MISP/PyMISPWarningLists).

## MISP warning lists: The dilemma of false-positive
- False-positive is a common issue in threat intelligence sharing.
- Its often a contextual issue:
- false-positive might be different per community of users sharing
information.
- organization might have their own view on false-positive.
- Based on the success of the MISP taxonomy model, we build misp-warninglists. They are lists of well-known indicators that can be
associated to potential false positives, errors or mistakes. They are Simple JSON files.

pull requests (https://github.com/MISP/misp-warninglists). Warning lists can be also used for critical or core infrastructure
warning, personally identifiable information...
