# Automation API 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. ### Automation URL The documentation will include a default MISP url in the examples. Don't forget to replace it with your MISP url. Default MISP url in the documentation: ~~~~ https:/// ~~~~ ### Automation key 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: ~~~~ Authorization: YOUR API KEY ~~~~ ### Accept and Content-Type headers 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: ~~~~ Content-Type: application/json Content-Type: application/xml ~~~~ ### XML Export An automatic export of all events and attributes (except file attachments) is available under a custom XML format. You can configure your tools to automatically download the following file: ~~~~ https:///events/xml/download ~~~~ If you only want to fetch a specific event append the eventid number: ~~~~ https:///events/xml/download/1 ~~~~ You can post an XML or JSON object containing additional parameters in the JSON query format or XML query format. Query parameters provide a way to filter the output to specific parameters. #### JSON query format The URL is appended with json: ~~~~ https:///events/xml/download.json ~~~~ The query parameters can be the following: ~~~~json {"request": {"eventid":["!51","!62"],"withAttachment":false,"tags":["APT1","!OSINT"],"from":false,"to":"2015-02-15"}} ~~~~ #### XML query format The URL is path is: ~~~~ https:///events/xml/download ~~~~ The query parameters can be the following: ~~~~xml !51!62falseAPT1!OSINTfalse2015-02-15 ~~~~ #### XML download and URL parameters The XML download also accepts two additional the following optional parameters in the url: ~~~~ https:///events/xml/download/[eventid]/[withattachments]/[tags]/[from]/[to]/[last] ~~~~
eventid
Restrict the download to a single event
withattachments
A boolean field that determines whether attachments should be encoded and a second parameter that controls the eligible tags.
tags
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). For example, to include tag1 and tag2 but exclude tag3 you would use:
~~~~ https:///events/xml/download/false/true/tag1&&tag2&&!tag3 ~~~~
from
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.
to
Events with the date set to a date before the one specified in the to field (format: 2015-02-15). This filter will use the date of the event.
last
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.
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). ### CSV export An automatic export of attributes is available as CSV. Only attributes that are flagged "to_ids" will get exported. You can configure your tools to automatically download the following file: ~~~~ https:///events/csv/download ~~~~ You can specify additional flags for CSV exports as follows: ~~~~ https:///events/csv/download/[eventid]/[ignore]/[tags]/[category]/[type]/[includeContext]/[from]/[to]/[last] ~~~~
eventid
Restrict the download to a single event
ignore
Setting this flag to true will include attributes that are not marked "to_ids".
tags
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).
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: ~~~~ https:///events/csv/download/false/false/tag1&&tag2&&!tag3/Network%20activity/domain ~~~~
category
The attribute category, any valid MISP attribute category is accepted.
type
The attribute type, any valid MISP attribute type is accepted.
includeContext
Include the event data with each attribute.
from
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.
to
Events with the date set to a date before the one specified in the to field (format: 2015-02-15). This filter will use the date of the event.
last
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.
The keywords false or null should be used for optional empty parameters in the URL. To export the attributes of all events that are of the type "domain", use the following syntax: ~~~~ https:///events/csv/download/false/false/false/false/domain ~~~~ ### NIDS rules export 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: ~~~~ https:///events/nids/suricata/download https:///events/nids/snort/download ~~~~ The full API syntax is as follows: ~~~~ https:///events/nids/[format]/download/[eventid]/[frame]/[tags]/[from]/[to]/[last] ~~~~
format
The export format, can be "suricata" or "snort"
eventid
Restrict the download to a single event
frame
Some commented out explanation framing the data. The reason to disable this would be if you would like to concatenate a list of exports from various select events in order to avoid unnecessary duplication of the comments.
tags
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). For example, to include tag1 and tag2 but exclude tag3 you would use:
~~~~ https:///events/nids/snort/download/false/false/tag1&&tag2&&!tag3 ~~~~
from
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.

last
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.
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: ~~~~ https:///events/nids/suricata/download/null/true/!tag1 ~~~~ Administration is able to maintain a white-list containing host, domain name and IP numbers to exclude from the NIDS export. ## Hash - HIDS database export Automatic export of MD5/SHA1 checksums contained in file-related attributes. This list can be used to feed forensic software when searching for suspicious files. Only published events and attributes marked as IDS Signature are exported. You can configure your tools to automatically download all the MD5 hashes from MISP: ~~~~ https:///events/hids/md5/download ~~~~ Or the SHA1 hashes: ~~~~ https:///events/hids/sha1/download ~~~~ The API's full format is as follow: ~~~~ https:///events/hids/[format]/download/[tags]/[from]/[to]/[last] ~~~~
format
The export format, can be "md5" or "sha1"
tags
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). For example, to include tag1 and tag2 but exclude tag3 you would use:
~~~~ https:///events/hids/md5/download/tag1&&tag2&&!tag3 ~~~~
from
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.
to
Events with the date set to a date before the one specified in the to field (format: 2015-02-15). This filter will use the date of the event.
last
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.
The keywords false or null should be used for optional empty parameters in the URL. For example, to only show sha1 values from events tagged tag1, use: ~~~~ https:///events/hids/sha1/download/tag1 ~~~~ ## STIX export 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: ~~~~ https:///events/stix/download ~~~~ 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: ~~~~ https:///events/stix/download/[id]/[withAttachments]/[tags]/[from]/[to]/[last] ~~~~
id
The event's ID
withAttachments
Encode attachments where applicable
tags
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).
For example, to include tag1 and tag2 but exclude tag3 you would use: ~~~~ https:///events/stix/download/false/true/tag1&&tag2&&!tag3 ~~~~
from
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.
to
Events with the date set to a date before the one specified in the to field (format: 2015-02-15). This filter will use the date of the event.
last
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.
You can post an XML or JSON object containing additional parameters in the following formats. If you use JSON query objects: ~~~~ https:///events/stix/download.json ~~~~ ~~~~json {"request": {"id":["!51","!62"],"withAttachment":false,"tags":["APT1","!OSINT"],"from":false,"to":"2015-02-15"}} ~~~~ If you use XML query objects: ~~~~ https:///events/stix/download ~~~~ ~~~~xml !51!62falseAPT1!OSINTfalse2015-02-15 ~~~~ ### Various ways to narrow down the search results of the STIX export For example, to retrieve all events tagged "APT1" but excluding events tagged "OSINT" and excluding events #51 and #62 without any attachments: ~~~~ https:///events/stix/download/!51&&!62/false/APT1&&!OSINT/2015-02-15 ~~~~ To export the same events using a POST request use: ~~~~ https:///events/stix/download.json ~~~~ Together with this JSON object in the POST message: ~~~~json {"request": {"id":["!51","!62"],"tags":["APT1","!OSINT"],"from":"2015-02-15"}} ~~~~ XML is automatically assumed when using the STIX export: ~~~~ https:///events/stix/download ~~~~ 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): ~~~~xml !51!62APT1!OSINT2015-02-15 ~~~~ ## RPZ export You can export RPZ zone files for DNS level firewall by using the RPZ export functionality of MISP. The file generated will include all of the IDS 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:
tags
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).
id
The event's ID
from
Events with the date set to a date after the one specified in the from field (format: 2015-02-03)
to
Events with the date set to a date before the one specified in the to field (format: 2015-02-03)
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: ~~~~ https:///attributes/rpz/download/[tags]/[eventId]/[from]/[to]/[policy]/[walled_garden]/[ns]/[email]/[serial]/[refresh]/[retry]/[expiry]/[minim um_ttl]/[ttl] ~~~~ Or POST an XML or JSON object with the above listed options: ~~~~xml OSINT&&!OUTDATEDwalled-gardenteamliquid.net5h ~~~~ ~~~~json {"request": {"tags": ["OSINT", "!OUTDATED"], "policy": "walled-garden", "walled_garden": "teamliquid.net", "refresh": "5h"} ~~~~ ## Text export An export of all attributes of a specific type to a plain text file. By default only published and IDS flagged attributes are exported. You can configure your tools to automatically download the following files: ~~~~ https:///attributes/text/download/md5 https:///attributes/text/download/sha1 https:///attributes/text/download/sha256 https:///attributes/text/download/filename https:///attributes/text/download/filename|md5 https:///attributes/text/download/filename|sha1 https:///attributes/text/download/filename|sha256 https:///attributes/text/download/ip-src https:///attributes/text/download/ip-dst https:///attributes/text/download/hostname https:///attributes/text/download/domain https:///attributes/text/download/email-src https:///attributes/text/download/email-dst https:///attributes/text/download/email-subject https:///attributes/text/download/email-attachment https:///attributes/text/download/url https:///attributes/text/download/http-method https:///attributes/text/download/user-agent https:///attributes/text/download/regkey https:///attributes/text/download/regkey|value https:///attributes/text/download/AS https:///attributes/text/download/snort https:///attributes/text/download/pattern-in-file https:///attributes/text/download/pattern-in-traffic https:///attributes/text/download/pattern-in-memory https:///attributes/text/download/yara https:///attributes/text/download/vulnerability https:///attributes/text/download/attachment https:///attributes/text/download/malware-sample https:///attributes/text/download/link https:///attributes/text/download/comment https:///attributes/text/download/text https:///attributes/text/download/other https:///attributes/text/download/named pipe https:///attributes/text/download/mutex https:///attributes/text/download/target-user https:///attributes/text/download/target-email https:///attributes/text/download/target-machine https:///attributes/text/download/target-org https:///attributes/text/download/target-location https:///attributes/text/download/target-external ~~~~ 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: ~~~~ https:///attributes/text/download/ip-src/tag1&& ~~~~ As of version 2.3.38, it is possible to restrict the text exports on two additional flags. The first allows the user to restrict based on event ID, whilst the second is a boolean switch allowing non IDS flagged attributes to be exported. Additionally, choosing "all" in the type field will return all eligible attributes. ~~~~ https:///attributes/text/download/[type]/[tags]/[event_id]/[allowNonIDS]/[from]/[to]/[last] ~~~~
type
The attribute type, any valid MISP attribute type is accepted.
tags
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).
For example, to include tag1 and tag2 but exclude tag3 you would use: ~~~~ https:///attributes/text/download/all/tag1&&tag2&&!tag3 ~~~~
event_id
Restrict the results to the given event IDs.
allowNonIDS
Allow attributes to be exported that are not marked as "to_ids".
from
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.
to
Events with the date set to a date before the one specified in the to field (format: 2015-02-15). This filter will use the date of the event.
last
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.
The keywords false or null should be used for optional empty parameters in the URL. For example, to retrieve all attributes for event #5, including non IDS marked attributes too, use the following line: ~~~~ https:///attributes/text/download/all/null/5/true ~~~~ ## RESTful searches with XML result export It is possible to search the database for attributes based on a list of criteria. To return an event with all of its attributes, relations, shadowAttributes, use the following syntax: ~~~~ https:///events/restSearch/download/[value]/[type]/[category]/[org]/[tag]/[quickfilter]/[from]/[to]/[last] ~~~~
value
Search for the given value in the attributes' value field.
type
The attribute type, any valid MISP attribute type is accepted.
category
The attribute category, any valid MISP attribute category is accepted.
org
Search by the creator organisation by supplying the organisation idenfitier.
tags
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).
For example, to include tag1 and tag2 but exclude tag3 you would use: ~~~~ https:///events/restSearch/download/null/null/null/null/tag1&&tag2&&!tag3 ~~~~
quickfilter
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.
from
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.

last
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.
eventid
The events that should be included / excluded from the search
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): POST to: ~~~~ https:///events/restSearch/download ~~~~ POST message payload (XML): ~~~~xml red october1!15 ~~~~ POST message payload (JSON): ~~~~json {"request": {"value":"red october","searchall":1,"eventid":"!15"}} ~~~~ To just return a list of attributes, use the following syntax:
value
Search for the given value in the attributes' value field.
type
The attribute type, any valid MISP attribute type is accepted.
category
The attribute category, any valid MISP attribute category is accepted.
org
Search by the creator organisation by supplying the organisation identifier.
tags
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).
from
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.
to
Events with the date set to a date before the one specified in the to field (format: 2015-02-15). This filter will use the date of the event.
last
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.
eventid
The events that should be included / excluded from the search
The keywords false or null should be used for optional empty parameters in the URL. ~~~~ https:///attributes/restSearch/download/[value]/[type]/[category]/[org]/[tag]/[from]/[to]/[last]/[eventid] ~~~~ Value, type, category and org are optional. It is possible to search for several terms in each category by joining them with the '&&' operator. It is also possible to negate a term 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). For example, in order to search for all attributes created by your organisation that contain 192.168 or 127.0 but not 0.1 and are of the type ip-src, excluding the events that were tagged tag1 use the following syntax: ~~~~ https:///attributes/restSearch/download/192.168&&127.0&&!0.1/ip-src/false/CIRCL/!tag1 ~~~~ 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: ~~~~ https:///attributes/restSearch/download/192.168.1.1|16/ip-src/null/CIRCL ~~~~ ## Export attributes of event with specified type as XML If you want to export all attributes of a pre-defined type that belong to an event, use the following syntax: ~~~~ https:///attributes/returnAttributes/download/[id]/[type]/[sigOnly] ~~~~ 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: ~~~~ https:///attributes/returnAttributes/download/25/md5&&sha256&&!filename/true ~~~~ ## Filtering event metadata As described in the REST section, it is possible to retrieve a list of events along with their metadata by sending a GET request to the /events API. However, this API in particular is a bit more versatile. You can pass search parameters along to search among the events on various fields and retrieve a list of matching events (along with their metadata). Use the following URL: ~~~~ https:///events/index ~~~~ POST a JSON object with the desired lookup fields and values to receive a JSON back. An example for a valid lookup: ~~~~ Authorization: Accept: application/json Content-type: application/json ~~~~ Body: ~~~~json {"searchinfo":"Locky", "searchpublished":1, "searchdistribution":0} ~~~~ The list of valid parameters:
searchpublished:
Filters on published or unpulished events [0,1] - negatable
searchinfo:
Filters on strings found in the event info - negatable
searchtag:
Filters on attached tag names - negatable
searcheventid:
Filters on specific event IDs - negatable
searchthreatlevel:
Filters on a given event threat level [1,2,3,4] - negatable
searchdistribution:
Filters on the distribution level [0,1,2,3] - negatable
searchanalysis:
Filters on the given analysis phase of the event [0,1,2,3] - negatable
searchattribute:
Filters on a contained attribute value - negatable
searchorg:
Filters on the creator organisation - negatable
searchemail:
Filters on the creator user's email address (admin only) - negatable
searchDatefrom:
Filters on the date, anything newer than the given date in YYYY-MM-DD format is taken - non-negatable
searchDateuntil:
Filters on the date, anything older than the given date in YYYY-MM-DD format is taken - non-negatable
## Download attachment or malware sample If you know the attribute ID of a malware-sample or an attachment, you can download it with the following syntax: ~~~~ https:///attributes/downloadAttachment/download/[Attribute_id] ~~~~ ## Download malware sample by hash 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. https:///attributes/downloadSample/[hash]/[allSamples]/[eventID] POST message payload (XML): ~~~~ 7c12772809c1c0c3deda6103b10fdfa0113 ~~~~ POST message payload (json): ~~~~ {"request": {"hash": "7c12772809c1c0c3deda6103b10fdfa0", "allSamples": 1, "eventID": 13}} ~~~~ A description of all the parameters in the passed object:
hash
A hash in MD5 format. If allSamples is set, this can be any one of the following: md5, sha1, sha256.
allSamples
If set, it will return all samples from events that have a match for the hash provided above.
eventID
If set, it will only fetch data from the given event ID.
## Upload malware samples using the "Upload Sample" API ~~~~ https:///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: ~~~~json {"request": {"files": [{"filename": filename1, "data": base64encodedfile1}, {"filename": filename2, "data": base64encodedfile2}], "optional_parameter1", "optional_parameter2", "optional_parameter3"}} ~~~~ JSON: ~~~~json {"request":{"files": [{"filename": "test1.txt", "data": "dGVzdA=="}, {"filename": "test2.txt", "data": "dGVzdDI="}], "distribution": 1, "info" : "test", "event_id": 15}} ~~~~ XML: ~~~~xml test3.txtdGVzdA==test4.txtdGVzdDI=test115 ~~~~ The following optional parameters are expected:
event_id
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.
distribution
The distribution setting used for the attributes and for the newly created event, if relevant. [0-3]
to_ids
You can flag all attributes created during the transaction to be marked as "to_ids" or not.
category
The category that will be assigned to the uploaded samples. Valid options are: Payload delivery, Artifacts dropped, Payload Installation, External Analysis.
info
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.
analysis
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]
comment
This will populate the comment field of any attribute created using this API.
## Add or remove tags from events You can add or remove an existing tag from an event in the following way: ~~~~ https:///events/addTag https:///events/removeTag ~~~~ Just POST a JSON object in the following format (to the appropriate API depending on whether you want to add or delete a tag from an event): ~~~~json {"request": {"Event": {"id": "228", "tag": "8"}}} ~~~~ Where "tag" is the ID of the tag. You can also use the name of the tag the following way (has to be an exact match): ~~~~json {"request": {"Event": {"id": "228", "tag": "OSINT"}}} ~~~~ ## Proposals API You can interact with the proposals via the API directly since version 2.3.148. |HTTP|URL|Explanation|Expected Payload|Response| |----|---|-----------|----------------|--------| |GET|/shadow_attributes/view/[proposal_id]|View a proposal|N/A|ShadowAttribute object| |POST|/shadow_attributes/add/[event_id]|Propose a new attribute to an event|ShadowAttribute object|ShadowAttribute object| |POST|/shadow_attributes/edit/[attribute_id]|Propose an edit to an attribute|ShadowAttribute object|ShadowAttribute object| |POST|/shadow_attributes/accept/[proposal_id]|Accept a proposal|N/A|Message| |POST|/shadow_attributes/discard/[proposal_id]|Discard a proposal|N/A|Message| When posting a shadow attribute object, use the following format JSON: ~~~~json {"request": {"ShadowAttribute": {"value": "5.5.5.5", "to_ids": false, "type": "ip-dst", "category": "Network activity"}}} ~~~~ XML: ~~~~xml 5.5.5.50ip-srcNetwork activity ~~~~ None of the above fields are mandatory, but at least one of them has to be provided. ## Sharing groups MISP allows sharing groups to be retrieved via the API. ~~~~ https:///sharing_groups/index.json ~~~~ Based on the API key used, the list of visible sharing groups will be returned in a JSON file. The JSON includes the organization parts of a given sharing group along with the associated server. ## Enable and disable feeds via the API The MISP feeds can be enabled via the API. A feed can be enabled by POSTing on the following url (feed_id is the id of the feed): ~~~~ /feeds/enable/feed_id ~~~~ A feed can be disabled by POSTing on the following url (feed_id is the id of the feed): ~~~~ /feeds/disable/feed_id ~~~~ ## Sightings API 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:///sightings/add/[attribute_id] https:///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:
id
The attribute's ID
uuid
The attribute's UUID
value
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
values
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
timestamp
Unix timestamp of the sighting, overrides the current time
Some examples: To create a sighting for attribute #9001: ~~~~json {"id":"9001"} ~~~~ To create a sighting for any attribute with the value being teamliquid.net or 173.231.136.216 with the time of sighting being : ~~~~json {"values":["teamliquid.net", "173.231.136.216"], "timestamp":1460558710} ~~~~ 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:///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. An example STIX sightings document: ~~~~xml Example watchlist that contains IP information. Indicators - Watchlist Domain Watchlist malicious1.example.com##comma##malicious2.example.com##comma##malicious3.example.com FooBar Inc. malicious2.example.com ~~~~ POSTing this as the message's body to MISP will sight any attributes visible to the user with he value "malicious2.example.com". For composite types, a match on a component will also trigger a sighting (so for example for attributes of type domain|ip a domain match would be sufficient). If no Related observables are set in the Sighting itself, MISP will fall back to the observable directly contained in the indicator. So in the following example: ~~~~xml Example watchlist that contains IP information. Indicators - Watchlist Domain Watchlist malicious1.example.com##comma##malicious2.example.com##comma##malicious3.example.com FooBar Inc. ~~~~ MISP would create sightings for attributes matching any of the following: malicious1.example.com, malicious2.example.com, malicious3.example.com # Describe types API MISP can procedurally describe all attribute types and attribute categories it currently supports including the category - type mappings. To access this information simply send a GET request to: ~~~~ https:///attributes/describeTypes ~~~~ Depending on the headers passed the returned data will be a JSON object or an XML, with 3 main sections: types, categories, category\_type\_mappings. # Attribute statistics API If you are interested in the attribute type or attribute category data distribution on your instance, MISP offers an API that will create an aggregates list. To access the API, simple sent a GET request to: ~~~~ https:///attributes/attributeStatistics/[context]/[percentage] ~~~~ Where the following parameters can be set:
Context
Set whether you are interested in the type or category statistics of your instance. This parameter can be either set to "type" or "category", with type being the default setting if the parameter is not set.
Percentage
An optional field, if set, it will return the results in percentages instead of the count.
The results are always returned as JSON. Sample output of the types in percentages from CIRCL's MISP instance: ~~~~json { "AS": "0.015%", "attachment": "0.177%", "btc": "0.005%", "campaign-name": "0.005%", "comment": "1.47%", "domain": "15.992%", "domain|ip": "0.005%", "email-attachment": "0.207%", "email-dst": "0.121%", "email-src": "0.192%", "email-subject": "0.146%", "filename": "3.698%", "filename|md5": "0.349%", "filename|sha1": "0.894%", "filename|sha256": "0.652%", "hostname": "17.558%", "http-method": "0.045%", "ip-dst": "7.087%", "ip-src": "2.707%", "link": "5.748%", "malware-sample": "0.702%", "malware-type": "0.005%", "md5": "21.064%", "mutex": "0.278%", "named pipe": "0.03%", "other": "1.495%", "pattern-in-file": "0.192%", "pattern-in-memory": "0.303%", "pattern-in-traffic": "0.051%", "regkey": "0.126%", "regkey|value": "0.187%", "sha1": "8.921%", "sha256": "5.597%", "snort": "0.045%", "target-machine": "0.248%", "target-org": "0.01%", "target-user": "0.106%", "text": "0.934%", "threat-actor": "0.005%", "url": "2.258%", "user-agent": "0.081%", "vulnerability": "0.182%", "whois-registrant-email": "0.01%", "x509-fingerprint-sha1": "0.01%", "yara": "0.086%" } ~~~~ # Automation using PyMISP PyMISP is a Python library to access MISP platforms via their REST API. PyMISP allows you to fetch events, add or update events/attributes, add or update samples or search for attributes. [PyMISP is available](https://github.com/MISP/PyMISP) including a documentation with various examples.
