IEP04: IntelMQ Data Format - Meta-Information
by Sebastian Waldbauer 22 Apr '21

22 Apr '21

Dear IntelMQ Developers and Users, nowadays security incidents are more important than 10 years ago. As IntelMQ can be used as core element for automated security incident handling, we would like to provide a way to share information with other intelmq instances. This proposal is also an alternative to IEP03 insofar as solving the "multiple values" is possible by using UUIDs so "link" related events in a backwards-compatible manner. If you're interested, please let us know, so we could organize a hackathon for further discussions about the specification of the meta-information. Previously this idea was discussed in [0] and [1]. [0] https://github.com/certtools/intelmq/blob/version-3.0-ideas/docs/architectu… [1] https://github.com/certtools/intelmq/issues/1521 # IEP04: Internal Data Format: Meta Information and Data Exchange To ease data exchange between two or more IntelMQ instances, adding some meta-information to the events can make this sharing easier in certain regards. "Linking" events could be based on the same theory as `git` using it - with parent hashes ( we would call it UUID ). ### TL;DR Communication between one or more IntelMQ instances & exchange data with a backwards-compatible format. P2P or centralized architecture is a big topic, which has to be discussed after the format is being set. ### Why is metadata important? Short and simple. To avoid race conditions & being able to discard/drop already processed events from other instances. ### Meta information Metadata is used to transfer some general data, which is not likely related to the event itself. It's more or less just an information to keep events clear & sortable. A message could look like: { "meta": { "version": 1, # protocol version, so we are allowed to fallback to old versions too "uuid": { current: "cert_at:aaaa-bbbb-cccc-dddd" # format to be decided parent: "cert_at:xxxx-yyyy-zzzz-ffff" # format to be discussed, if not set -> current is the parent uuid }, "type": "event", "format": "intelmq", # i. e. this field could contain "n6" or "idea", so the receiving component can decode on demand. }, "payload": { # normal intelmq data "source.ip": "127.0.0.1", "source.fqdn": "example.com", "raw": base64-blob } } Tell us your opinion about adding non-standardized meta-information fields ( i. e. RTIR ticket number, origin, other local contact informationen ... and so on ) #### The UUID For the UUID there are multiple options: 1. Generate a random 128 bit UUID 2. A list of entities, which dealt with this event already. For example if an event was passed on from cert-at to cert-ee, the field could look like `!cert-at!cert-ee`. A message sending loop can be detected if the own name is already in this field upon reception. 3. Using CyCat: `publisher-short-name:project-short-name:UUID`. For example: `cert-at:intelmq:72ddb00c-2d0a-4eea-b7ac-ae122b8e6c3b`, or `cert-pl:n6:f60c9fb9-81f9-4e0b-8a44-ea41326a15b3`. Some more research and discussion is required before the implementation of this option. Have a look at https://www.cycat.org/services/concept/ for more details. 4. A hash: A benefit using a hash is that we're able to recalculate them on every intelmq instance. ### Exporting events to other systems In IntelMQ 2.x the events only comprise of the "payload" and no meta information. For local storages like file output or databases, the meta information may not be relevant in some use-cases. So it needs to be possible to export events *without* meta information, which is also the backwards-compatible behaviour. The "type" field exists in the current format as "__type" in the flat payload structure. In the output bots there's currently a boolean parameter `message_with_type` to include the field `__type` in the "export". For optionally exporting meta-information like uuid or format, a similar logic could be used. ### How can data exchange work? This now depends on how IntelMQ instances can communicate, either Peer-to-peer or via a central data hub. Both of them do have pro's and con's. #### P2P ( Peer 2 Peer ) Decentralized network + Less downtimes: A downtime of one instance, does not affect the whole network + Better privacy: data is not shared to an unrelated instance + More secure: data can optionally be encrypted (key-exchange between instances?) + Decentralized and local maintenance ~ Network latency depends on server locations - Networking issues may occur How would data exchange looks like between two instances: 1) Instance A has events which should be relayed to Instance B & C, because they're not sure who the actually receiver should be 2) Instance A ensures all messages have a UUID 3) Instance A sends the data to Instance B & Instance C 4) Instance B checks the data & they're sure that the data should be for Instance C 5) Instance C receives data from Instance A & Instance B 6) Instance C checks the UUID, which is the same & drops the package from Instance B #### (Central) Data hub + Less maintenance: Is maintained by the hub administrator + Central data storage (reports can optionally be cached to be downloaded later) ~ Central data analysis (e.g. statistics) is possible ~ Network latency depends on server locations - point of failure: if network problems occur, no exchange is possible As already seen above, data exchange here would be less complicated. The sending may look like: 1) Instance A has events which should be relayed to Instance B (e.g. different country) 2) Instance A ensures all messages have a UUID 3) Instance A sends these messages to the data hub The reception side can look like: 1) Instance B connects to central instance 2) Instance B queries and downloads all available messages 3) Upon reception, all messages are de-duplicated based on the UUID: a) If the UUID is already known, discard the message b) If the UUID has not been seen before, continue with processing To sum up, both exchange variants are useful. More research is needed, i. e. a mixed infrastructure with centralized parts but can be decentralized too. However, this shall not be neither the purpose nor the aim of this IEP. -- // Sebastian Waldbauer <waldbauer(a)cert.at> - T: +43 1 5056416 7202 // CERT Austria - https://www.cert.at/ // Eine Initiative der nic.at GmbH - https://www.nic.at/ // Firmenbuchnummer 172568b, LG Salzburg

IEP03: IntelMQ Data Format - Multiple Values
by Sebastian Waldbauer 22 Apr '21

22 Apr '21

Dear IntelMQ Developers and Users, an evaluation of current challenges with the internal data format led to the idea of allowing multiple values for one field in IntelMQ 3.0 (scheduled for June 2021)[0]. The idea is described below, including various advantages and disadvantages. We appreciate your input, opinion and analysis of further implications on this idea. We plan to evaluate the feedback that emerged in two weeks. [0] https://github.com/certtools/intelmq/blob/version-3.0-ideas/docs/architectu… "The new IDF shall support (sorted) lists of IPs, domains, taxonomy categories, etc. By convention the most relevant item in such a list MUST be the first item in the sorted list." https://github.com/certtools/intelmq/blob/version-3.0-ideas/docs/architectu…: n6-system "Since the new IDF shall support multiple values, mapping to n6 should be rather easy." ## Use-cases ### Network information IntelMQ's format currently allows for *exactly one* value per field. For example, every event can have *one* `source.ip` and *one* `source.fqdn`. In some use-cases, multiple values can be useful, for example when querying DNS information. One domain (`source.fqdn`) can point to multiple IP addresses (`source.ip`). The other way round, multiple domains point to the same IP address is also very common. The use-case first appeared was that one IP address can be part of multiple Autonomous systems (`source.asn`).[1][2][3] See the examples below in section Format. [1]: "Multiple ASNs/networks per IP? #543" https://github.com/certtools/intelmq/issues/543 [2]: "BOT: DNS lookup #373" https://github.com/certtools/intelmq/issues/373 [3]: "reverse DNS: Only first record is used "https://github.com/certtools/intelmq/issues/877 ### Classification Another use-case is to use multiple classifications.[5] For example, if a website was hacked and used for a phishing page, it can be assigned two classifications: For the hacking: Taxonomy: information-content-security, type: unauthorised-modification-of-information For the phishing page: Taxonomy: fraud, type: phishing Another example are reachable networks services, which should not be accessible by the internet. Shadowserver provides a lot of this data. Open XDMCP instances are both DDoS amplifiers and Potentially unwanted accessible systems. Therefore both classifications apply: Taxonomy: vulnerable, type: ddos-amplifier Taxonomy: vulnerable, type: potentially-unwanted-accessible-system A list of all fields on the RSIT can be found in the RSIT repository[6] [5]: https://github.com/enisaeu/Reference-Security-Incident-Taxonomy-Task-Force/… [6]: https://github.com/enisaeu/Reference-Security-Incident-Taxonomy-Task-Force/… ## Format Some examples: {"source.ip": ["192.0.43.8"], "source.asn": [16876, 40528]} {"source.ip": ["10.0.0.1", "10.0.0.2"], "source.url": ["http://example.com/", "http://example.net"]} {"classification.taxonomy": ["information-content-security", "fraud"], "classification.type": ["unauthorised-modification-of-information", "phishing"], "source.url": ["http://example.com/"], "source.ip": ["10.0.0.1", "10.0.0.2"]} In the bots' code multiple values need to be taken car of. For example, instead of: ip_addr = event["source.ip"] # do stuff it is necessary to loop over the values: for ip_addr in event["source.ip"]: # do stuff This logic is required for *all* fields which can have multiple values, therefore nested loops may be necessary. Everything which processes IntelMQ data needs to be adapted, including data bases. See the "Disadvantages" section below. ### Optional back-conversion ("value-explosion") One variant/option of this IEP is to create a conversion layer from the new multi-value format to the old one-value format by creating multiple events with only one value per field. Using this conversion, compatibility with external components can be kept, while the advantages only exist inside the IntelMQ core (ie. the bots). Examples: {"source.ip": ["127.0.0.1", "127.0.0.2"], "source.fqdn": ["example.com"]} -> {"source.ip": "127.0.0.1", "source.fqdn": ["example.com"]}, {"source.ip": "127.0.0.2", "source.fqdn": ["example.com"]} {"source.ip": ["127.0.0.1", "127.0.0.2"], "source.fqdn": ["example.com", "example.org"]} -> {"source.ip": "127.0.0.1", "source.fqdn": "example.com"}, {"source.ip": "127.0.0.1", "source.fqdn": "example.org"}, {"source.ip": "127.0.0.2", "source.fqdn": "example.com"}, {"source.ip": "127.0.0.2", "source.fqdn": "example.org"} ### What will change? We'll change the behaviour of the current IntelMQ internal parsing process, i. e. you'll be able to add multiple IP addresses to on field, which will be handled as multiple events, but merged into one event. This will allow us to combine i. e. a domain with multiple IP addresses to one event. ### Advantages Supporting multiple values allows us to add multiple IP addresses to one event. As opposed to using multiple events with nearly similar data, the multiple-value approach reduces data duplication and has less overhead, while on the other hand the complexity increases. If multiple events would be used instead, related events would need to be linked together by other means (see section Alternative below). ### Disadvantages (breaking behaviour) The complexity in IntelMQ and all linked components increases without doubt. All components dealing with the IntelMQ-data need to be adapted to deal with multiple values. This includes all bots, but IntelMQ administrators need to adapt their configurations (e.g. filters, etc.) as well. Without the explosion-variant, all connected databases need to be adapted (e.g. PostgreSQL, SQLite, Elastic, MongoDB etc.) additionally and all software which is processing data from IntelMQ need to be adapted. PostgreSQL support arrays for columns, but the scheme conversion can be complex and resource-hungry. IntelMQ followed the KISS ("keep it simple, stupid")[4] principle from its beginning. It is disputable if multiple values breaks with this principle. [4]: https://en.wikipedia.org/wiki/KISS_principle ## Alternatives An alternative to using multiple values per field is to set unique identifiers (e.g. UUID) per event and let events with the same origin have the same "parent" identifier. This way, related events can be linked and compatibility is easier. Relating the events to each other requires extra steps although, but keeps the KISS principle. This approach will be described in IEP04. To solve the use-case of multiple classifications per event, the primary and most important classification can be used instead of multiple ones. A possible solution for the classification use-case above would be to some sort of tagging - in short "tags". I. e. { "source.ip": ["192.0.43.8"], "source.asn": [16876, 40528], "tags": ["ddos-amplifier", "info-disclosure", "mirai-botnet"] } ## Other IoC processing formats For reference, we describe the formats of other IoC-processing systems similar to IntelMQ. Both formats, IDEA and n6 do support multiple values in different kinds. If you know of other similar formats supporting multiple values, please speak up! ### "IDEA" The IDEA-format, used by CESNET-developed Warden, supports multiple values for some fields. But the data format structure differs clearly from IntelMQ's, as you can see in the example below. The classification is defined per address and network ranges are possible as addresses, what is not supported in IntelMQ. IDEA was designed from scratch to overcome disadvantages of Warden's previous data format. Example: "Source": [ { "Type": ["Phishing"], "IP4": ["192.168.0.2-192.168.0.5", "192.168.0.10/25"], "IP6": ["2001:0db8:0000:0000:0000:ff00:0042::/112"], "Hostname": ["example.com"], "URL": ["http://example.com/cgi-bin/killemall"], "Proto": ["tcp", "http"], "AttachHand": ["att1"], "Netname": ["ripe:IANA-CBLK-RESERVED1"] } ], "Target": [ { "Type": ["Backscatter", "OriginSpam"], "Email": ["innocent(a)example.com"], "Spoofed": true }, { "IP4": ["10.2.2.0/24"], "Anonymised": true } ] Upstream documentation: https://idea.cesnet.cz/en/index https://warden.cesnet.cz/en/index ### n6 In the n6 format, the addr field is a list of arrays with `ip`, `asn`, `cc` and `dir` fields. `addr` is similar to IntelMQ's `source` namespace, but the size of `addr` is much lower and the "direction" of the address is given by a field inside the addr item. Example: [{"ipv6": "abcd::1", "cc": "PL", "asn": 12345, "dir": "dst"}] Upstream documentation: https://n6sdk.readthedocs.io/en/latest/tutorial.html#field-class-addressfie… https://n6sdk.readthedocs.io/en/latest/tutorial.html#field-class-extendedad… -- // Sebastian Waldbauer <waldbauer(a)cert.at> - T: +43 1 5056416 7202 // CERT Austria - https://www.cert.at/ // Eine Initiative der nic.at GmbH - https://www.nic.at/ // Firmenbuchnummer 172568b, LG Salzburg

regarding IEP03
by L. Aaron Kaplan 22 Apr '21

22 Apr '21

Hi everyone, I wanted to send back a better write-up of my stance on IEP03 ("multiple values" in the IntelMQ internal data format). Alas, I was quite busy and I am sprinting to push out some code for our deadline at work. However, let me summarise it: I think the IEP03 is very well written, thank you a lot for this! Thinking this through was important and I think Sebastian Waldbauer did a great job. Reading it, I realised that my initial proposal of having multiple values is really breaking the KISS principle of IntelMQ in a bad way. Worse than I had thought. So, I am thinking of retracting the proposal. However, .... https://github.com/certtools/ieps/tree/main/003#alternatives has a good core in it. If we have multiple values, instead of doing the n x m complexity explosion, we link different events (JSON rows) together via UUIDs this gives us what we need: * UUIDs help with deduplication! That's important when linking IntelMQ instances! * lower complexity / keep the KISS principle * consumers can ignore the UUID-linking if it's not relevant for them (f.ex enrichment processes/bots) * we can still represent linked events. I would like to add one little but important thing for the UUID linking idea: add a "link-type". Examples for link-types: * parent-child event * grouping types (all of these events belong to the same report) etc. With this triplet information , we are close to RDF (left-side, type, right-side) and thus we can (future-proof) represent any type of relation. A list of valid types needs to be documented in the IDF format page of course. So, I think with that, we can go ahead. Thanks, a. PS: and sorry that my feedback came a bit late, as said - code sprints.

It took me a while to fix all the errors but it works again since approximately one week. If you encounter any errors, please reply back or create an issue.
