Objavljeni su novi detalji o hakiranju infrastrukture decentralizirane platforme za razmjenu poruka Matrix, o kojem je izvije\u0161teno ujutro. Problemi su nastali kroz sustav kontinuirane integracije Jenkins, koji je hakiran 13. o\u017eujka. Zatim je na Jenkins serveru presretnut preusmjereni SSH-prijem jednog od administratora, a 4. travnja napada\u010di su dobili pristup drugim serverima infrastrukture.<\/p>\n

Tijekom drugog napada, web stranica matrix.org preusmjerena je na drugi server (matrixnotorg.github.io) putem izmjene DNS postavki, koriste\u0107i presretnuti klju\u010d za API sustava za dostavu sadr\u017eaja Cloudflare. Prilikom rekonstrukcije sadr\u017eaja poslu\u017eitelja<\/a> nakon prvog hakiranja, administratori Matrixa a\u017eurirali su samo nove osobne klju\u010deve, a propustili su a\u017eurirati klju\u010d za Cloudflare. <\/p>\n

Tijekom drugog napada, serveri Matrix ostali su netaknuti, a promjene su se ograni\u010dile samo na zamjenu adresa u DNS-u. Ako je korisnik ve\u0107 promijenio lozinku nakon prvog napada, nije potrebno ponovo je mijenjati. No, ako lozinka jo\u0161 nije promijenjena, treba je a\u017eurirati \u0161to je prije mogu\u0107e, jer je curenje baze s he\u0161iranim lozinkama potvr\u0111eno. Trenutno se planira pokretanje procesa prisilnog resetiranja lozinke pri sljede\u0107em prijavljivanju.<\/p>\n

Osim curenja lozinki, tako\u0111er je potvr\u0111eno da su napada\u010di do\u0161li u posjed GPG klju\u010deva, koji se koriste za stvaranje digitalnih potpisa paketa u Debian repozitoriju Synapse i izdanja Riot\/Web. Klju\u010devi su bili za\u0161ti\u0107eni lozinkom. Trenutno su klju\u010devi ve\u0107 opozvani. Klju\u010devi su presretnuti 4. travnja, ali od tada nema novih izdanja Synapsea, iako je izdan klijent Riot\/Web 1.0.7 (preliminary check showed that it was not compromised). <\/p>\n

Napada\u010d je objavio niz izvje\u0161taja s detaljima napada na GitHubu, ali su oni uklonjeni. Ipak, u arhivu su se sa\u010duvali izvje\u0161taji.
