Fwd: [routing-wg] RPKI Outage Post-Mortem

by Massimiliano Stucchi

If you're not on the routing-wg mailing list, there's something you should know -------- Forwarded Message -------- Subject: [routing-wg] RPKI Outage Post-Mortem Date: Tue, 25 Feb 2020 15:12:15 +0100 From: Nathalie Trenaman <nathalie(a)ripe.net> To: routing-wg(a)ripe.net Dear colleagues, From Saturday 22 February at 08:24 (CET), any newly created, modified, or deleted ROAs (176 in total) could not be added to our publication server due to a disk problem. From that moment on, all the data was stored on the database, but the publication did not happen. The disk did not report any problems and, therefore, no engineer was alerted of this incident. Due to the disk problem, starting from Sunday 23 February at 09:10 (CET), our CRL expired and our repository could not be properly updated. This was reported to us on Monday 24 February at 11:44 (CET). Immediately, our engineers fixed the disk problem, however, since the CRL expired, all underlying objects also expired. Depending on the Relying Party software an operator used, this abnormal behaviour appeared differently. Initially, our engineers tried to do a full re-population of the RPKI repository, but unfortunately, this did not update the CRL in the validation tree. At 15:03 (CET), we performed a full CA key-roll, which was completed at 21:02 (CET) and resolved the problem. At 19:58 (CET), all objects in the backlog were published. We apologise for any inconvenience this may have caused and we are taking all the necessary steps to ensure this incident does not appear again in the future. Kind regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

MELANI / GovCERT.ch

by Andreas Fink

Hello Swinog Users, Has anyone of you received some info from MELANI / GovCERT about some IoT vulnerability you might be exposed to? Well I did and I found very very strange things in this report. 1. The report contains only a timestamp, an IP address and a DNS name. Not which vulnerability, not potential loopholes, traces or ANYTHING useful to analyze whats happening. 2. The single IP address in the report is not in my network (I used to have that IP range in the past but I sold it in 2016. So long long ago. ) 3. The abuse email they sent the report to is not in the whois of that network. 4. The DNS name used in the report is not the reverse PTR of that IP. Nor does the forward DNS point to that IP. 5. The DNS name points to a host in my network but that host is definitively not a IoT device which has any kind of default password. Its a solid Linux machine with a up to date distribution with 2 usernames only on it with very secure passwords and only one specific application running which doesn't talk to outside my network at all. If that machine would have gotten hacked, it would surprise me very much. At least I have found nothing unusual on that IP. No unexpected network activity, CPU load, processes etc. So MELANI tells me my big fat Linux server is now a IOT device which has default passwords and I should simply do a factory default (and by doing this erase terabytes of data). I should look for "_SOMETHING_" without specifying it on SOME IP I don't own. And they address such a report to me while I am not the abuse contact of this SOME_IP. Furthermore SOME_IP looked not being reachable anyway when I tested. So the report contains ZERO usable information. The only thing which might not be wrong in the report is the timestamp (but thats not verified neither). I am shocked that a government entity which should take security seriously, is sending out such utter nonsense reports and wasting all our precious time. If they got such reports from 3rd parties it should contain verifiable information and USEFUL information. Apparently MELANI has become some kind of open CERT-SMTP relay without authentication. Let me know your experiences.

Telegram group

by Massimiliano Stucchi

Hi everyone, I created a telegram group for Swinog. It is meant to be a place to have discussions that are more informal than what you could have on the mailing list or simply for something more interactive. The link to join is https://t.me/SWINOG I've created a similar group for ITNOG almost two years ago and it proved to be a good initiative, now with about 450 members and with daily discussion on different topics. Maybe we can make it happen also for Swinog. Keep in mind this is just a personal initiative and not an official one from Swinog. If it works out and it's positive, we'll see if we can make it more official. If you have any question or comment, please feel free to approach me. Ciao! -- Massimiliano Stucchi MS16801-RIPE Twitter/Telegram: @stucchimax

RIPE Atlas probes as SW

by Steven.Glogger＠swisscom.com

Hi There Just saw this post by RIPE: https://labs.ripe.net/Members/alun_davies/ripe-atlas-software-probes RIPE Atlas probes are now available as software, offering future hosts a new way to help build the RIPE Atlas network. While not a replacement for their hardware counterparts, software probes will improve coverage by bringing RIPE Atlas to new and previously hard-to-reach places. How cool is that?! 😊 greetings -steven
