Udviklerne af platformen for decentraliseret beskedudveksling, Matrix, har annonceret en n\u00f8dafbrydelse af serverne Matrix.org og Riot.im (den prim\u00e6re Matrix-klient) p\u00e5 grund af et hack af projektets infrastruktur. Den f\u00f8rste afbrydelse fandt sted i g\u00e5r aftes, hvorefter servernes funktion blev genoptaget, og applikationerne blev genopbygget fra de officielle kildekoder. Men for f\u00e5 minutter siden blev serverne kompromitteret for anden gang. <\/p>\n

Angriberne har offentliggjort detaljerede oplysninger om serverkonfiguration<\/a> og beviser for, at de besidder en database med hashes fra n\u00e6sten fem og en halv millioner brugere af Matrix. Som bevis er hash af projektlederen for Matrix blevet offentliggjort. Den \u00e6ndrede kode til hjemmesiden er offentliggjort i angribernes repository p\u00e5 GitHub (ikke i det officielle matrix-repository). Der mangler endnu detaljer om det andet hack.<\/p>\n

Efter det f\u00f8rste hack offentliggjorde Matrix-teamet en rapport, der angav, at indtr\u00e6ngen blev udf\u00f8rt via en s\u00e5rbarhed i den ikke-opdaterede Jenkins CI-system. Efter at have f\u00e5et adgang til server<\/a> Jenkins, havde angriberne mulighed for at opsnappe SSH-n\u00f8gler og f\u00e5 adgang til andre servere i infrastrukturen. Det blev oplyst, at kildekoden og pakkerne ikke blev ramt af angrebet. Angrebet ber\u00f8rte heller ikke serverne hos Modular.im. Men angriberne fik adgang til den prim\u00e6re databasesystem (DBS), hvorunder ogs\u00e5 usikrede beskeder, adgangstokens og password-hashes opbevares.<\/p>\n

Alle brugere blev p\u00e5budt at \u00e6ndre deres adgangskoder. Men under \u00e6ndringen af adgangskoderne i den prim\u00e6re klient, Riot, st\u00f8dte brugerne p\u00e5 problemer med tab af filer med backup-n\u00f8gler til gendannelse af krypterede beskeder og manglende adgang til historikken for tidligere beskeder.<\/p>\n

Vi minder om, at platformen til organisering af decentraliseret kommunikation, Matrix, pr\u00e6senteres som et projekt, der bruger \u00e5bne standarder og l\u00e6gger stor v\u00e6gt p\u00e5 at sikre brugerens sikkerhed og privatliv. Matrix tilbyder end-to-end kryptering baseret p\u00e5 den velafpr\u00f8vede Signal-algoritme, underst\u00f8tter s\u00f8gning og ubegr\u00e6nset gennemsyn af beskedhistorik, kan bruges til filoverf\u00f8rsel, sending af meddelelser, vurdering af udviklerens online tilstedev\u00e6relse, organisering af videokonferencer, samt til stemme- og videoopkald. Der underst\u00f8ttes ogs\u00e5 avancerede funktioner som tekstindtastningsnotifikationer, l\u00e6sebekr\u00e6ftelse, push-notifikationer og server-side s\u00f8gning, synkronisering af historik og klientstatus, forskellige identifikatorer (e-mail, telefonnummer, Facebook-konto osv.).
