Utvecklarna av plattformen f\u00f6r decentraliserad meddelandeutbyte Matrix har meddelat att de har st\u00e4ngt ner servrarna Matrix.org och Riot.im (huvudklienten f\u00f6r Matrix) p\u00e5 grund av en hackning av projektets infrastruktur. Den f\u00f6rsta nedst\u00e4ngningen intr\u00e4ffade ig\u00e5r kv\u00e4ll, efter vilken servrarna \u00e5terst\u00e4lldes och apparna rekonstruerades fr\u00e5n referens k\u00e4llkoder. Men f\u00f6r n\u00e5gra minuter sedan blev servrarna komprometterade igen. <\/p>\n

Angriparna publicerade detaljerad information om p\u00e5 projektets huvudsida serverkonfigurationen<\/a> och data som visar att de har en databas med hashar fr\u00e5n n\u00e4stan fem och ett halvt miljoner anv\u00e4ndare av Matrix. Som bevis publicerades en hash av l\u00f6senordet f\u00f6r projektledaren f\u00f6r Matrix offentligt. Den \u00e4ndrade koden f\u00f6r webbplatsen har lagts i angriparnas repository p\u00e5 GitHub (inte i det officiella repositoryt f\u00f6r matrix). Detaljer om den andra hackningen saknas f\u00f6r tillf\u00e4llet.<\/p>\n

Efter den f\u00f6rsta hackningen publicerade Matrix laget en rapport som angav att hackningen utf\u00f6rdes genom en s\u00e5rbarhet i det icke uppdaterade systemet f\u00f6r kontinuerlig integration Jenkins. Efter att ha f\u00e5tt tillg\u00e5ng till servern<\/a> Jenkins f\u00e5ngade angriparna SSH-nycklar och fick m\u00f6jlighet att f\u00e5 tillg\u00e5ng till andra servrar i infrastrukturen. Det har rapporterats att k\u00e4llkoden och paketen inte skadades som en f\u00f6ljd av attacken. Attacken p\u00e5verkade inte heller servrarna Modular.im. Men angriparna fick \u00e5tkomst till den prim\u00e4ra databasen, d\u00e4r bland annat okrypterade meddelanden, \u00e5tkomsttokens och hashade l\u00f6senord finns.<\/p>\n

Alla anv\u00e4ndare fick instruktioner att byta l\u00f6senord. Men under processen att byta l\u00f6senord i huvudsak klienten Riot st\u00f6tte anv\u00e4ndarna p\u00e5 att filer med s\u00e4kerhetskopior av nycklar f\u00f6r att \u00e5terst\u00e4lla krypterade meddelanden f\u00f6rsvann och de kunde inte f\u00e5 tillg\u00e5ng till historiken med tidigare meddelanden.<\/p>\n

Vi p\u00e5minner om att plattformen f\u00f6r decentraliserad kommunikation, Matrix, presenterar sig som ett projekt som anv\u00e4nder \u00f6ppna standarder och l\u00e4gger stor vikt vid att s\u00e4kerst\u00e4lla anv\u00e4ndarens s\u00e4kerhet och integritet. Matrix tillhandah\u00e5ller end-to-end-kryptering baserat p\u00e5 den bepr\u00f6vade Signal-algoritmen, st\u00f6der s\u00f6kning och obegr\u00e4nsad visning av chattloggar, kan anv\u00e4ndas f\u00f6r fil\u00f6verf\u00f6ring, aviseringar, n\u00e4rvarov\u00e4rdering av utvecklare online, organisering av telekonferenser samt genomf\u00f6rande av r\u00f6st- och videosamtal. Ut\u00f6kade funktioner som avisering om skrivande, l\u00e4skvittnen, push-notiser och serverbaserad s\u00f6kning, historik- och status-synkronisering f\u00f6r klienter samt olika identifieringsalternativ (e-post, telefonnummer, Facebook-konto, osv.) st\u00f6ds ocks\u00e5.
