misp-warninglist

misp-warninglists are lists of well-known indicators that can be associated to potential false positives, errors or mistakes.

The warning lists are integrated in MISP to display an info/warning box at the event and attribute level if such indicators are available in one of the list. The list can be globally enabled or disabled in MISP following the practices of the organization.

Format of a warning list

{
  "name": "List of known public DNS resolvers",
  "version": 1,
  "description": "Event contains one or more public DNS resolvers as attribute with an IDS flag set",
  "matching_attributes": [
    "ip-src",
    "ip-dst"
  ],
  "list": [
    "8.8.8.8",
    "8.8.4.4",
    "208.67.222.222",
    "208.67.220.220",
    "195.46.39.39",
    "195.46.39.40"
  ]
}

If matching_attributes are not set, the list is matched against any type of attributes.

type of warning list

• string (default) - perfect match of a string in the warning list against matching attributes
• substring - substring matching of a string in the warning list against matching attributes
• hostname - hostname matching (e.g. domain matching from URL) of a string in the warning list against matching attributes
