The internet is dead, long live the internets! In 2025, the internet will consist of either gated communities or decentralised independent instances. For those who want to be connected while choosing their own dependencies, there is no other option than to draw up new networks and experiment with both historical and innovative protocols. Networks with an Attitude is a six-day worksession organised by Constant. During this intensive week we stretch the imagination of what a network is, and (...)

Spécial @thibnton !

Jeudi 20 juin vers 0000 UTC, un certain nombre de domaines ont été redirigés vers les serveurs de noms de Ztomy. Voici par exemple ce qui est arrivé au plus célèbre de ces domaines, linkedin.com, vu par DNSDB <►http://www.bortzmeyer.org/dnsdb.html> :

first seen 2013-06-20 00:17:09 -0000
last seen 2013-06-20 04:13:15 -0000
linkedin.com. NS ns1617.ztomy.com.
linkedin.com. NS ns2617.ztomy.com.

Selon certains témoignages, 50 000 domaines sont concernés. Cisco, par observation passive du DNS (comme DNSDB), en a confirmé 5 000 <▻http://blogs.cisco.com/security/hijacking-of-dns-records-from-network-solutions>.

Les serveurs de noms de Ztomy ne fournissant pas les réponses attendues, plus personne ne pouvait accéder aux services de ces domaines. Cela a logiquement fait du buzz <▻http://www.theregister.co.uk/2013/06/20/linkedin_dns_hijacked> <▻http://www.reddit.com/r/netsec/comments/1gpl3p/linkedin_dns_has_been_hijacked_pointing_at_rogue> <▻http://techcrunch.com/2013/06/19/linkedin-outage-due-to-possible-dns-hijacking> mais, comme souvent en ce qui concerne le DNS, sans informations techniques fiables et avec un vocabulaire très flou (« DNS poisoning » utilisé à tort et à travers).

Le bureau d’enregistrement de linkedin.com, Network Solutions, reconnait sa faute, dans un communiqué très court en détail et contenant au moins une grosse erreur (le problème n’était pas Web mais DNS) <▻https://www.networksolutions.com/blog/2013/06/important-update-for-network-solutions-customers-experiencing-webs>

Le meilleur article de synthèse sur ce problème, fait par des gens compétents, est celui de l’ISC <▻http://www.isc.org/blogs/hijacking-dns-error-ddos-what-happened-and-what-you-can-do>.

Il semble donc bien que le problème soit une erreur humaine ou un bogue : voulant rediriger des domaines attaqués vers un service de mitigation des attaques par déni de service (un service qu’on paie pour que la guerre ait lieu chez eux), Network Solutions s’est trompé et a envoyé ses clients chez Ztomy. Moins sexy qu’un piratage mais plus courant. Il y a plus de maladroits que de cyberguerriers chinois ou iraniens.

L’incident a rappelé la difficulté de la coordination dans l’Internet : une fois le problème corrigé, il a fallu vider les caches des résolveurs DNS <▻http://www.bortzmeyer.org/vider-cache-resolveur.html>, qui gardaient la mauvaise information en mémoire. Des tentatives de la part de Network Solutions, via des messages non authentifiés et ne contenant aucun détail ont suscité quelques sarcasmes <▻https://lists.dns-oarc.net/pipermail/dns-operations/2013-June/010346.html>.

Le problème continue sans doute en ce moment, puisque les TTL des domaines sont souvent très longs (ici, deux jours) :

craigslist.com. 172800 IN NS ns1620.ztomy.com.
craigslist.com. 172800 IN NS ns2620.ztomy.com.

Freedom In the Cloud

What do we need? We need a really good webserver you can put in your pocket and plug in any place. In other words, it shouldn’t be any larger than the charger for your cell phone and you should be able to plug it in to any power jack in the world and any wire near it or sync it up to any wifi router that happens to be in its neighborhood. It should have a couple of USB ports that attach it to things. It should know how to bring itself up. It should know how to start its web server, how to collect all your stuff out of the social networking places where you’ve got it. It should know how to send an encrypted backup of everything to your friends’ servers. It should know how to microblog. It should know how to make some noise that’s like tweet but not going to infringe anybody’s trademark. In other words, it should know how to be you …oh excuse me I need to use a dangerous word - avatar - in a free net that works for you and keeps the logs.
