Compromiterea contului de administrator a dus la o \u00eentrerupere de aproape patru ore a activit\u0103\u021bii celui de-al doilea operator de telecomunica\u021bii din Spania, Orange Espagne, care deserve\u0219te 11 milioane de abona\u021bi. A fost folosit o parol\u0103 previzibil\u0103 «ripeadmin» pentru accesul la interfa\u021ba registratorului RIPE NCC \u0219i nu a fost activat\u0103 autentificarea cu doi factori. <\/p>\n

Parola pentru RIPE a fost interceptat\u0103 \u00een timpul unei infect\u0103ri a sistemului unui angajat cu malware \u0219i a fost disponibil\u0103 pe pie\u021bele negre de la \u00eenceputul lunii septembrie. Este notabil c\u0103, pe l\u00e2ng\u0103 contul Orange Espagne, \u00een bazele de date men\u021bionate se afl\u0103 \u0219i mii de alte conturi pentru acces la access.ripe.net, care pot fi folosite poten\u021bial pentru atacuri similare. <\/p>\n

Incidentul a r\u0103mas neobservat p\u00e2n\u0103 pe 2 ianuarie, c\u00e2nd un vandal a p\u0103truns \u00een web-interfa\u021ba RIPE NCC \u0219i a efectuat modific\u0103ri \u00een set\u0103rile BGP \u0219i RPKI (Infrastructure Public Key Resource), dup\u0103 care, timp de aproape patru ore, rutarea a fost perturbat\u0103 pentru aproximativ jum\u0103tate din traficul operatorului de telecomunica\u021bii. Ac\u021biunile atacatorilor au dus la faptul c\u0103 tehnologia RPKI, destinat\u0103 protej\u0103rii anun\u021burilor BGP de falsificare, a fost folosit\u0103 pentru a bloca anun\u021burile legitime. <\/p>\n

Atacatorul a creat mai multe \u00eenregistr\u0103ri noi RPKI ROA (Route Origin Authorization), printre care s-au num\u0103rat \u00eenregistr\u0103ri ce legau blocuri mari de adrese ale Orange Espagne de o alt\u0103 sistem autonom, ceea ce a dus la blocarea anun\u021burilor BGP corecte de c\u0103tre sistemul autonom al acestui operator pe ruterele multor operatori de backbone. Drept urmare, num\u0103rul rutelor BGP asociate cu Orange Espagne a sc\u0103zut de la 9200 la 7400, iar traficul a sc\u0103zut aproape cu 50%.

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

RPKI (Infrastructure Public Key Resource) este utilizat\u0103 pentru autorizarea anun\u021burilor BGP \u0219i permite determinarea dac\u0103 un anun\u021b BGP provine de la proprietarul re\u021belei sau nu. Atunci c\u00e2nd se utilizeaz\u0103 RPKI pentru sistemele autonome \u0219i adreselor IP<\/a> se construie\u0219te o structur\u0103 de \u00eencredere de la IANA la registratorii regionali (RIRs), apoi la furnizorii (LIR) \u0219i consumatorii finali, care permite ter\u021bilor s\u0103 se asigure c\u0103 opera\u021biunea cu resursa a fost efectuat\u0103 de c\u0103tre de\u021bin\u0103torul s\u0103u. F\u0103r\u0103 utilizarea autoriz\u0103rii, orice operator poate anun\u021ba o subre\u021bea cu informa\u021bii false despre lungimea rutei \u0219i poate ini\u021bia tranzitarea unei p\u0103r\u021bi din traficul altor sisteme care nu aplic\u0103 filtrarea anun\u021burilor.
