Automation functionality is designed to automatically generate signatures for intrusion detection systems. To enable signature generation for a given attribute, Signature field of this attribute must be set to Yes. Note that not all attribute types are applicable for signature generation, currently we only support NIDS signature generation for IP, domains, host names, user agents etc., and hash list generation for MD5/SHA1 values of file artifacts. Support for more attribute types is planned. To to make this functionality available for automated tools an authentication key is used. This makes it easier for your tools to access the data without further form-based-authentication.
The authentication of the automation is performed via a secure key available in the MISP UI interface. Make sure you keep that key secret as it gives access to the entire database! The API key is available in the event actions menu under automation.
Since version 2.2 the usage of the authentication key in the url is deprecated. Instead, pass the auth key in an Authorization header in the request. The legacy option of having the auth key in the url is temporarily still supported but not recommended.
The authorization is performed by using the following header:
When performing your request, depending on the type of request, you might need to explicitly specify in what content type you want to get your results. This is done by setting one of the below Accept headers:
~~~~
Accept: application/json
Accept: application/xml
~~~~
When submitting data in a POST, PUT or DELETE operation you also need to specify in what content-type you encoded the payload. This is done by setting one of the below Content-Type headers:
<dd>Events with the date set to a date after the one specified in the from field (format: 2015-02-15). This filter will use the date of the event.</dd>
<dd>Events published within the last x amount of time, where x can be defined in days, hours, minutes (for example 5d or 12h or 30m). This filter will use the published timestamp of the event.</dd>
The keywords false or null should be used for optional empty parameters in the URL. Also check out the User Guide to read about the [REST API](../using-the-system/README.md#rest-api).
<dd>Setting this flag to true will include attributes that are not marked "to_ids".</dd>
<dt>tags</dt>
<dd>To include a tag in the results just write its names into this parameter. To exclude a tag prepend it with a '!'. You can also chain several tag
commands together with the '&&' operator. Please be aware the colons (:) cannot be used in the tag search. Use semicolons instead (the search will automatically search for colons instead).</dd>
</dl>
For example, to include tag1 and tag2 but exclude tag3 you would use:
For example, to only download a csv generated of the "domain" type and the "Network activity" category attributes all events except for the one and further restricting it to events that are tagged "tag1" or "tag2" but not "tag3", only allowing attributes that are IDS flagged use the following syntax:
<dd>Events with the date set to a date after the one specified in the from field (format: 2015-02-15). This filter will use the date of the event.</dd>
<dd>Events published within the last x amount of time, where x can be defined in days, hours, minutes (for example 5d or 12h or 30m). This filter will use the published timestamp of the event.</dd>
Automatic export of all network related attributes is available under the Snort or Suricata rule format. Only published events and attributes marked as IDS Signature are exported.
You can configure your tools to automatically download the following file:
<dd>Events with the date set to a date after the one specified in the from field (format: 2015-02-15). This filter will use the date of the event.</dd>
<dd>Events published within the last x amount of time, where x can be defined in days, hours, minutes (for example 6d or 12h or 30m). This filter will use the published timestamp of the event.</dd>
The keywords false or null should be used for optional empty parameters in the URL.
An example for a Suricata export for all events excluding those tagged tag1, without all of the commented information at the start of the file would look like this:
<dd>Events with the date set to a date after the one specified in the from field (format: 2015-02-15). This filter will use the date of the event.</dd>
<dd>Events published within the last x amount of time, where x can be defined in days, hours, minutes (for example 5d or 12h or 30m). This filter will use the published timestamp of the event.</dd>
You can export MISP events in MITRE's STIX format (to read more about [STIX](https://stix.mitre.org/)). The STIX XML export is currently very slow and can lead to timeouts with larger events or collections of events. The STIX JSON return format does not suffer from this issue.
Usage of the API:

~~~~
Search parameters can be passed to the function via url parameters or by POSTing an xml or json object (depending on the return type). The following parameters can be passed to the STIX export tool: id, withAttachments, tags. Both id and tags can use the && (and) and ! (not) operators to build queries. Using the url parameters, the syntax is as follows:
<dd>To include a tag in the results just write its names into this parameter. To exclude a tag prepend it with a '!'. You can also chain several tag commands together with the '&&' operator. Please be aware the colons (:) cannot be used in the tag search. Use semicolons instead (the search will automatically search for colons instead).</dd>
</dl>
For example, to include tag1 and tag2 but exclude tag3 you would use:
<dd>Events with the date set to a date after the one specified in the from field (format: 2015-02-15). This filter will use the date of the event.</dd>
<dd>Events published within the last x amount of time, where x can be defined in days, hours, minutes (for example 5d or 12h or 30m). This filter will use the published timestamp of the event.</dd>
XML is automatically assumed when using the STIX export:

The same search could be accomplished using the following POSTed XML object (note that ampersands need to be escaped, or alternatively separate id and tag elements can be used):
flagged domain, hostname and IP-src/IP-dst attribute values that you have access to.
It is possible to further restrict the exported values using the following filters:
<dl>
<dt>tags</dt>
<dd>To include a tag in the results just write its names into this parameter. To exclude a tag prepend it with a '!'. You can also chain several tag
commands together with the '&&' operator. Please be aware the colons (:) cannot be used in the tag search when passed through the url. Use semicolons
instead (the search will automatically search for colons instead).</dd>
<dt>id</dt>
<dd>The event's ID</dd>
<dt>from</dt>
<dd>Events with the date set to a date after the one specified in the from field (format: 2015-02-03)</dd>
<dt>to</dt>
<dd>Events with the date set to a date before the one specified in the to field (format: 2015-02-03)</dd>
</dl>
MISP will inject header values into the zone file as well as define the action taken for each of the values that can all be overwritten. By default these values are either the default values shipped with the application, or ones that are overwritten by your site administrator. The values are as follows:
| Value name | Default value |
| --- | :---: |
|RPZ_policy| DROP|
|RPZ_walled_garden| 127.0.0.1|
|RPZ_serial| $date00|
|RPZ_refresh| 2h|
|RPZ_retry| 30m|
|RPZ_expiry| 30d|
|RPZ_minimum_ttl| 1h|
|RPZ_ttl| 1w|
|RPZ_ns| localhost.|
|RPZ_email| root.localhost|
To override the above values, either use the url parameters as described below:
To restrict the results by tags, use the usual syntax. Please be aware the colons (:) cannot be used in the tag search. Use semicolons instead (the search will automatically search for colons instead). To get ip-src values from events tagged tag1 but not tag2 use:
<dd>The attribute type, any valid MISP attribute type is accepted.</dd>
<dt>tags</dt>
<dd>To include a tag in the results just write its names into this parameter. To exclude a tag prepend it with a '!'. You can also chain several tag commands together with the '&&' operator. Please be aware the colons (:) cannot be used in the tag search. Use semicolons instead (the search will automatically search for colons instead).</dd>
</dl>
For example, to include tag1 and tag2 but exclude tag3 you would use:
<dd>Events with the date set to a date after the one specified in the from field (format: 2015-02-15). This filter will use the date of the event.</dd>
<dd>Events published within the last x amount of time, where x can be defined in days, hours, minutes (for example 5d or 12h or 30m). This filter will use the published timestamp of the event.</dd>
<dd>Search for the given value in the attributes' value field.</dd>
<dt>type</dt>
<dd>The attribute type, any valid MISP attribute type is accepted.</dd>
<dt>category</dt>
<dd>The attribute category, any valid MISP attribute category is accepted.</dd>
<dt>org</dt>
<dd>Search by the creator organisation by supplying the organisation idenfitier.</dd>
<dt>tags</dt>
<dd>To include a tag in the results just write its names into this parameter. To exclude a tag prepend it with a '!'. You can also chain several tag
commands together with the '&&' operator. Please be aware the colons (:) cannot be used in the tag search. Use semicolons instead (the search will automatically search for colons instead).</dd>
</dl>
For example, to include tag1 and tag2 but exclude tag3 you would use:
<dd>Enabling this (by passing "1" as the argument) will make the search ignore all of the other arguments, except for the auth key and value. MISP will return an xml / json (depending on the header sent) of all events that have a sub-string match on value in the event info, event orgc, or any of the attribute value1 / value2 fields, or in the attribute comment.</dd>
<dd>Events with the date set to a date after the one specified in the from field (format: 2015-02-15). This filter will use the date of the event.</dd>
<dd>Events published within the last x amount of time, where x can be defined in days, hours, minutes (for example 5d or 12h or 30m). This filter will use the published timestamp of the event.</dd>
<dd>The events that should be included / excluded from the search</dd>
</dl>
The keywords false or null should be used for optional empty parameters in the URL.
For example, to find any event with the term "red october" mentioned, use the following syntax (the example is shown as a POST request instead of a GET, which is highly recommended):
To just return a list of attributes, use the following syntax:
<dl>
<dt>value</dt>
<dd>Search for the given value in the attributes' value field.</dd>
<dt>type</dt>
<dd>The attribute type, any valid MISP attribute type is accepted.</dd>
<dt>category</dt>
<dd>The attribute category, any valid MISP attribute category is accepted.</dd>
<dt>org</dt>
<dd>Search by the creator organisation by supplying the organisation identifier.</dd>
<dt>tags</dt>
<dd>To include a tag in the results just write its names into this parameter. To exclude a tag prepend it with a '!'. You can also chain several tag commands together with the '&&' operator. Please be aware the colons (:) cannot be used in the tag search. Use semicolons instead (the search will automatically search for colons instead).</dd>
<dd>Events with the date set to a date after the one specified in the from field (format: 2015-02-15). This filter will use the date of the event.</dd>
<dd>Events published within the last x amount of time, where x can be defined in days, hours, minutes (for example 5d or 12h or 30m). This filter will use the published timestamp of the event.</dd>
You can also use search for IP addresses using CIDR. Make sure that you use '|' (pipe) instead of '/' (slashes). Please be aware the colons (:) cannot be used in the tag search. Use semicolons instead (the search will automatically search for colons instead). See below for an example:
sigOnly is an optional flag that will block all attributes from being exported that don't have the IDS flag turned on. It is possible to search for several types with the '&&' operator and to exclude values with the '!' operator. For example, to get all IDS signature attributes of type md5 and sha256, but not filename|md5 and filename|sha256 from event 25, use the following:
You can also download samples by knowing its MD5 hash. Simply pass the hash along as a JSON/XML object or in the URL (with the URL having overruling the passed objects) to receive a JSON/XML object back with the zipped sample base64 encoded along with some contextual information.
You can also use this API to get all samples from events that contain the passed hash. For this functionality, just pass the "allSamples" flag along.
Note that if you are getting all samples from matching events, you can use all supported hash types (md5, sha1, sha256) for the lookup.
You can also get all the samples from an event with a given event ID, by passing along the eventID parameter. Make sure that either an event ID or a hash is passed along, otherwise an error message will be returned. Also, if no hash is set, the allSamples flag will get set automatically.
## Upload malware samples using the "Upload Sample" API
~~~~
https://<mispurl>/events/upload_sample/[Event_id]
~~~~
This API will allow you to populate an event that you have modify rights to with malware samples (and all related hashes). Alternatively, if you do not supply an event ID, it will create a new event for you.
The files have to be base64 encoded and POSTed as explained below. All samples will be zipped and password protected (with the password being "infected"). The hashes of the original file will be captured as additional attributes.
The event ID is optional. MISP will accept either a JSON or an XML object posted to the above URL.
The general structure of the expected objects is as follows:
<dd>The Event's ID is optional. It can be either supplied via the URL or the POSTed object, but the URL has priority if both are provided. Not supplying an event ID will cause MISP to create a single new event for all of the POSTed malware samples. You can define the default settings for the event, otherwise a set of default settings will be used.</dd>
<dt>distribution</dt>
<dd>The distribution setting used for the attributes and for the newly created event, if relevant. [0-3]</dd>
<dt>to_ids</dt>
<dd>You can flag all attributes created during the transaction to be marked as "to_ids" or not.</dd>
<dt>category</dt>
<dd>The category that will be assigned to the uploaded samples. Valid options are: Payload delivery, Artifacts dropped, Payload Installation, External Analysis.</dd>
<dt>info</dt>
<dd>Used to populate the event info field if no event ID supplied. Alternatively, if not set, MISP will simply generate a message showing that it's a malware sample collection generated on the given day.</dd>
<dt>analysis</dt>
<dd>The analysis level of the newly created event, if applicable. [0-2] threat_level_id: The threat level ID of the newly created event, if applicatble. [0-3]</dd>
MISP allows Sightings data to be conveyed in several ways.
The most basic way is to POST a blank message to the Sightings API with the attribute ID or attribute UUID. This will create a sightings entry with the creation of the entry as the timestamp for the organisation of the authenticated user.
~~~~
https://<mispurl>/sightings/add/[attribute_id]
https://<mispurl>/sightings/add/[attribute_uuid]
~~~~
Alternatively, it is possible to POST a JSON object and gain additional granularity. The following fields are recognised by the API:
<dl>
<dt>id</dt>
<dd>The attribute's ID</dd>
<dt>uuid</dt>
<dd>The attribute's UUID</dd>
<dt>value</dt>
<dd>Will create a sighting for any attribute with the given value or for composite attributes, for the value matching any element of the attribute value</dd>
<dt>values</dt>
<dd>Expects a list, MISP will create sightings for any attribute matching any of the given values or for composite attributes, for any of the values matching any element of the attribute value</dd>
It is also possible to POST a STIX indicator with sighting data to the following URL (keep in mind that the content type has to be XML):
~~~~
https://<mispurl>/sightings/add/stix
~~~~
MISP will use the sighting's related observables to gather all values and create sightings for each attribute that matches any of the values. If no related observables are provided in the Sighting object, then MISP will fall back to the Indicator itself and use its observables' values to create the sightings. The time of the sighting is the current time, unless the timestamp attribute is set on the Sightings object, in which case that is taken.
