Now on RIPE Labs: BGP Communities - A Weapon for the Internet
by Mirjam Kuehne 21 Mar '19

21 Mar '19

Dear colleagues, In these two articles on RIPE Labs Franziska Lichtblau and Florian Streibelt present a new attack vector on the Internet routing infrastructure using BGP communities: https://labs.ripe.net/Members/florian_streibelt/bgp-communities-a-weapon-fo… https://labs.ripe.net/Members/florian_streibelt/bgp-communities-a-weapon-fo… In the meantime this study won the Applied Networking Research Prizes and will be presented at the Internet Research Task Force meeting next week in Prague. Kind regards, Mirjam Kühne RIPE NCC

2019-03 New Policy Proposal (BGP Hijacking is a RIPE Policy Violation) to be discussed on Anti-Abuse Working Group Mailing List
by Marco Schmidt 19 Mar '19

19 Mar '19

Dear colleagues, A new RIPE Policy proposal, 2019-03, "BGP Hijacking is a RIPE Policy Violation", is now available for discussion. This proposed policy is of interest to both the Anti-Abuse and Routing working groups. The chairs of both these working groups have agreed to keep the discussion on one single mailing list to avoid duplication, and for formal consideration of the proposal within the RIPE Policy Development Process. You are therefore requested to share your feedback on this proposal with the Anti-Abuse mailing list. The goal of this proposal is to define that BGP hijacking is not accepted as normal practice within the RIPE NCC service region. You can find the full proposal at: https://www.ripe.net/participate/policies/proposals/2019-03 We encourage you to review this proposal and send your comments to <anti-abuse-wg(a)ripe.net> before 17 April 2019. Kind regards, Marco Schmidt Policy Officer RIPE NCC

RIS dumps, 0.0.0.0/0 routes and RPKI validator 3
by nusenu 18 Mar '19

18 Mar '19

Hello, I've got some really strange results when talking to rpki-validator 3's API and after some up and downgrading I concluded that it has to be in the RIS dumps (that was the only static data regardless of the validator version) and then I found the likely cause: AS15576 announcing 0.0.0.0/0 As of writing this email the first entry on this page: https://rpki-validator.ripe.net/bgp-preview but when we look at: https://stat.ripe.net/widget/as-routing-consistency#w.resource=AS15576 it is not there. I assumed RIPEstat uses the same data source (RIS) just with some less delay. Are 0.0.0.0/0 routes filtered by RIPEstat but included in RIS dumps? Should rpki-validator filter them out? thanks, nusenu -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu

RPKI Validator 3: RIS dump downloads - still plain HTTP
by nusenu 12 Mar '19

12 Mar '19

Hi, back in September I opened an issue on github [1] about RPKI Validator 3 fetching RIS dumps via plain HTTP connections, two weeks ago the issue got closed. First I was glad since I assumed the issue got closed because it is fixed but then I noticed that the issue still persists in rpki-validator-3.0-377 so I'm wondering why the issue got closed? thanks, nusenu [1] https://github.com/RIPE-NCC/rpki-validator-3/issues/50 -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu

routing based on AS values
by Niels ten Oever 08 Mar '19

08 Mar '19

Dear Routing WG, Recent public debates on the ethics and social implications of digital technology, as well as the feedback I received on my presentation at RIPE77 [0], have stimulated me to think more about how value frameworks can inform routing decisions. Based on the analysis of several discussions in the IETF community [1], the ICANN community [2], and the recent book by David Clarke [3], I thought a voluntary declaration of values might be relevant for discussion in the RIPE community. A way of doing this could be the discussion of the introduction of two AS-SET objects in the routing database. This could enable Autonomous Systems to declare the values frameworks they adhere to. An example of possible objects would be: [object0] as-set: AS-GDPR remarks: members of this set declare to be compliant with the General Data Protection Regulation of the European Union mbrs-by-ref: ANY [/object0] [object1] as-set: AS-UNGP remarks: members of this set declare to have adopted and implemented the United Nations Guiding Principles on Business and Human Rights mbrs-by-ref: ANY [/object1] Members of these sets would declare to live up to these values. Based on these sets, other AS-es could, for example, choose to preferentially route via AS-es that are member of (one of) these sets. These value frameworks (the GDPR and UNGPs) were chosen because these are widely known and adopted standards in our community [4], so the understanding of these values should not be subject to a lot of interpretation and discussion. Do you think this would be a reasonable approach, and if so, in what ways could these objects be used to route traffic? Or would there be better ways to route traffic based on the values of AS-es? Looking forward to hear what you think. Best, Niels PS I posted a similar e-mail to the database WG to discuss the implications for the database. Please accept my apologies if this is considered as cross-posting, but I thought both aspects of this proposal might be interesting to discuss. [0] https://ripe77.ripe.net/archives/video/2113/ [1] For instance in the discussions on RFC1958, RFC3935, RFC6873, RFC7258, and RFC8280 [2] Most notably resulting in the addition of a commitment to human rights during the IANA transition, but of course as well during the extensive WHOIS discussions [3] https://mitpress.mit.edu/books/designing-internet [4] For instance SIDN has engaged in a Human Rights Impact Assessment https://www.sidn.nl/a/over-sidn/mensenrechten-daar-voldoen-we-toch-aan , and Cisco, Ericsson, Google, NTT, Orange, AT&T, IBM and many others have adopted the UNGPs https://www.business-humanrights.org/en/cisco-systems-0 - Cisco https://www.business-humanrights.org/en/cisco-systems-0?keywords=cisco - Ericsson https://www.business-humanrights.org/en/ericsson-0?keywords=ericsson#a117755 - Google https://www.business-humanrights.org/en/google-0?keywords=google - NTT https://www.business-humanrights.org/en/nippon-telegraph-and-telephone-ntt-… http://www.ntt.co.jp/csr_e/report.html - Orange https://www.business-humanrights.org/en/orange-0 - AT&T https://www.business-humanrights.org/en/att-0?keywords=AT&T - IBM https://www.business-humanrights.org/en/ibm-0?keywords=IBM -- Niels ten Oever Researcher and PhD Candidate Datactive Research Group University of Amsterdam PGP fingerprint 2458 0B70 5C4A FD8A 9488 643A 0ED8 3F3A 468A C8B3

Analysing traffic in context of rejecting RPKI invalids using pmacct
by Job Snijders 13 Feb '19

13 Feb '19

Dear all, Whether to deploy RPKI Origin Validation with an "invalid == reject" policy really is a business decision. One has to weigh the pros and cons: what are the direct and indirect costs of accepting misconfigurations or hijacks for my company? what is the cost of deploying RPKI? What is the cost of honoring misconfigured RPKI ROAs? There are a few thousand misconfigured ROAs, what does this mean for me? To answer these questions, Paolo Lucente and myself worked to extend pmacct traffic analysis engine (http://pmacct.net/) in such a way that it can do perform the RFC 6811 Origin Validation procedure and present the outcome as a property in the flow aggregation process. Pmacct has the ability to ingest BGP feeds and correlate the BGP data to the sflow/netflow/ipfix data. This allows for fantastic business intelligence, you can see exactly how much traffic is flowing from what customers to what endpoints for what reason! Pmacct implemented Origin Validation in a cute way: it separates out RPKI invalid BGP announcements into two categories: a) "invalid with no overlapping or alternative route" (aka will be blackholed if 'invalid == reject') b) "invalid but an overlapping unknown/valid announcement also exists" (end-to-end connectivity can still work). Because pmacct separates out the various types kinds of (invalid) BGP announcements, operators don't have to do deploy *anything* in their network to get a good grasp on how their connectivity to the rest of the Internet would look like after deploying a "invalid == reject" policy. No changes to your network configurations are required to make use of this feature, you don't need to tag routes with communities or do other tricks. All the analysis happens inside pmacct. Of course we tested this first in the NTT global backbone AS 2914! At the moment of writing, we're seeing less than a handful of gigabits per second being send towards BGP announcements that are RPKI Invalid and for which no alternative route exists. In context of NTT's backbone that amount of traffic is just statistical noise. This is a very encouraging sign, it may help us move towards the goal of deploying RPKI Origin Validation in AS 2914. Nusenu wrote a great blog post on where these RPKI ROA misconfigurations are located, i recommend reading their posts to develop a better understanding of the problem space: https://medium.com/@nusenu/where-are-rpki-unreachable-networks-located-65c7… Even if you don't intend to deploy RPKI Origin Validation (or are single-homed), pmacct's RPKI capabilities can be useful in forensic investigations. It'll be easier to analyse how much and what kind of traffic for what period of time was sent to a possible hijack. This will help you when writing RFOs! If you want to testdrive this feature, fetch pmacct version 1.7.3-rc1 from https://github.com/pmacct/pmacct/releases/tag/1.7.3-rc1 Documentation on how to configure the feature: https://github.com/pmacct/pmacct/blob/master/QUICKSTART#L1783-#L1833 https://github.com/pmacct/pmacct/blob/master/CONFIG-KEYS#L2626-#L2647 Let us know what you think! Or if you'd like to chat telemetry with Paolo or me about analysing the effects of BGP hijacks and RPKI, we'll both be at the San Francisco NANOG meeting next week! Kind regards, Job

Real-time BGP hijacking detection: ARTEMIS-1.0.0 just released
by Vasileios Kotronis 21 Dec '18

21 Dec '18

Dear operators, FORTH's INSPIRE group and CAIDA are delighted to announce the public release of the ARTEMIS BGP prefix hijacking detection tool, available as open-source software at https://github.com/FORTH-ICS-INSPIRE/artemis ARTEMIS is designed to be operated by an AS in order to monitor BGP for potential hijacking attempts against its own prefixes. The system detects such attacks within seconds, enabling immediate mitigation. The current release has been tested at a major greek ISP, a dual-homed edge academic network, and a major US R&E backbone network. We would be happy if you'd give it a try and provide feedback. Feel free to make pull requests on GitHub and help us make this a true community project. ARTEMIS is funded by the RIPE NCC Community Projects 2017, European Research Council (ERC) grant agreement no. 338402 (NetVolution Project), the Comcast Innovation Fund, US NSF grants OAC-1848641 and CNS-1423659 and US DHS S&T contract HHSP233201600012C.

Fwd: BGP Experiment
by Job Snijders 20 Dec '18

20 Dec '18

For your information! ---------- Forwarded message --------- From: Italo Cunha <cunha(a)dcc.ufmg.br> Date: Thu, Dec 20, 2018 at 6:39 PM Subject: BGP Experiment To: NANOG <nanog(a)nanog.org>, DISCO experiment mailing list <disco-experiment(a)googlegroups.com> NANOG, We would like to inform you of an experiment to evaluate alternatives for speeding up adoption of BGP route origin validation (research paper with details [A]). Our plan is to announce prefix 184.164.224.0/24 with a valid standards-compliant unassigned BGP attribute from routers operated by the PEERING testbed [B, C]. The attribute will have flags 0xe0 (optional transitive [rfc4271, S4.3]), type 0xff (reserved for development), and size 0x20 (256bits). Our collaborators recently ran an equivalent experiment with no complaints or known issues [A], and so we do not anticipate any arising. Back in 2010, an experiment using unassigned attributes by RIPE and Duke University caused disruption in Internet routing due to a bug in Cisco routers [D, CVE-2010-3035]. Since then, this and other similar bugs have been patched [e.g., CVE-2013-6051], and new BGP attributes have been assigned (BGPsec-path) and adopted (large communities). We have successfully tested propagation of the announcements on Cisco IOS-based routers running versions 12.2(33)SRA and 15.3(1)S, Quagga 0.99.23.1 and 1.1.1, as well as BIRD 1.4.5 and 1.6.3. We plan to announce 184.164.224.0/24 from 8 PEERING locations for a predefined period of 15 minutes starting 14:30 GMT, from Monday to Thursday, between the 7th and 22nd of January, 2019 (full schedule and locations [E]). We will stop the experiment immediately in case any issues arise. Although we do not expect the experiment to cause disruption, we welcome feedback on its safety and especially on how to make it safer. We can be reached at disco-experiment(a)googlegroups.com.
