Kompromissningen av administrat\u00f6rskontot ledde till n\u00e4stan fyra timmars driftstopp f\u00f6r Spaniens n\u00e4st st\u00f6rsta teleoperat\u00f6r Orange Espagne, som betj\u00e4nar 11 miljoner abonnenter. F\u00f6r att f\u00e5 \u00e5tkomst till RIPE NCC:s registratorsgr\u00e4nssnitt anv\u00e4ndes det l\u00e4tt f\u00f6ruts\u00e4gbara l\u00f6senordet \"ripeadmin\" och tv\u00e5faktorsautentisering var inte aktiverad. <\/p>\n

L\u00f6senordet till RIPE f\u00e5ngades upp vid en infektion av en anst\u00e4llds system med skadlig programvara och hade sedan september funnits i f\u00f6rs\u00e4ljningsdatabaser p\u00e5 svarta marknaden med komprometterade l\u00f6senord. Det \u00e4r anm\u00e4rkningsv\u00e4rt att f\u00f6rutom Orange Espagnes konto finns det ocks\u00e5 tusentals andra konton f\u00f6r att ansluta till access.ripe.net, vilka potentiellt kan anv\u00e4ndas f\u00f6r att genomf\u00f6ra liknande attacker. <\/p>\n

Incidenten f\u00f6rblev obem\u00e4rkt fram till den 2 januari, n\u00e4r en vandalisering intr\u00e4ffade i webbgraficen f\u00f6r RIPE NCC och \u00e4ndringar gjordes i BGP- och RPKI (Resource Public Key Infrastructure)-inst\u00e4llningarna, vilket ledde till att routingen f\u00f6r ungef\u00e4r h\u00e4lften av teleoperat\u00f6rens trafik st\u00f6rdes under n\u00e4stan fyra timmar. Angriparnas \u00e5tg\u00e4rder resulterade i att RPKI-teknologin, avsedd att skydda BGP-meddelanden fr\u00e5n f\u00f6rfalskning, anv\u00e4ndes f\u00f6r att blockera legitima meddelanden. <\/p>\n

Angriparen skapade flera nya RPKI ROA (Route Origin Authorization)-poster, d\u00e4ribland poster som kopplade stora block av Orange Espagnes adressomr\u00e5de till ett fr\u00e4mmande autonomt system, vilket resulterade i att korrekta BGP-meddelanden fr\u00e5n detta operat\u00f6rs autonomiska system blockeras p\u00e5 m\u00e5nga av de stora operat\u00f6rernas routrar. I slut\u00e4ndan minskade antalet BGP-rutter kopplade till Orange Espagne fr\u00e5n 9200 till 7400, och trafiken f\u00f6ll n\u00e4stan med h\u00e4lften.

\"Kompromissningen<\/center> <\/p>\n

RPKI (Resource Public Key Infrastructure) anv\u00e4nds f\u00f6r att auktorisera BGP-meddelanden och m\u00f6jligg\u00f6r att avg\u00f6ra om ett BGP-meddelande kommer fr\u00e5n n\u00e4tverks\u00e4garen eller inte. Vid anv\u00e4ndning av RPKI f\u00f6r autonoma system och IP-adresser<\/a> bygger en kedja av f\u00f6rtroende fr\u00e5n IANA till de regionala registratorerna (RIR), och sedan till leverant\u00f6rerna (LIR) och slutkonsumenterna, som g\u00f6r det m\u00f6jligt f\u00f6r tredje parter att verifiera att operationen med resursen utf\u00f6rdes av dess \u00e4gare. Utan auktorisering kan vilken operat\u00f6r som helst annonsera ett undermenyn med falsk information om rutans l\u00e4ngd och initiera transit av delar av trafiken fr\u00e5n andra system som inte till\u00e4mpar filtrering av annonser.
