La prima interruzione si \u00e8 verificata ieri sera, dopo di che i server sono stati ripristinati e le applicazioni ricostruite dai codici sorgente di riferimento. Ma pochi minuti fa, i server sono stati compromessi per la seconda volta. <\/p>\n<p>Gli attaccanti hanno pubblicato sulla homepage del progetto informazioni dettagliate su <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/server\/\"   title=\"configurazione del server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"995\">configurazione del server<\/a> e dati sulla disponibilit\u00e0 di un database con le password hash di quasi cinque milioni e mezzo di utenti di Matrix. Come prova, \u00e8 stata pubblicata in chiaro la hash della password del leader del progetto Matrix. Il codice del sito modificato \u00e8 stato pubblicato nel repository degli attaccanti su GitHub (non nel repository ufficiale di matrix). Attualmente non ci sono dettagli sul secondo attacco.<\/p>\n<p>Dopo il primo attacco, il team di Matrix ha pubblicato un rapporto in cui viene indicato che l'attacco \u00e8 stato effettuato attraverso una vulnerabilit\u00e0 in un sistema di integrazione continua Jenkins non aggiornato. Dopo aver ottenuto accesso a <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/server\/dts-shicago\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2849\">server<\/a> Jenkins, gli attaccanti hanno intercettato le chiavi SSH e ottenuto la possibilit\u00e0 di accedere ad altri server dell'infrastruttura. \u00c8 stato dichiarato che il codice sorgente e i pacchetti non sono stati danneggiati a causa dell'attacco. L'attacco non ha influito nemmeno sui server di Modular.im. Tuttavia, gli attaccanti hanno ottenuto accesso al database principale, che contiene anche messaggi non criptati, token di accesso e hash delle password.<\/p>\n<p>A tutti gli utenti \u00e8 stato ordinato di cambiare le proprie password. Tuttavia, durante il processo di cambiamento delle password nel client principale Riot, gli utenti hanno riscontrato la scomparsa di file di backup delle chiavi per il ripristino della corrispondenza crittografata e l'impossibilit\u00e0 di accedere alla cronologia dei messaggi passati.<\/p>\n<p>Ricordiamo che la piattaforma per l'organizzazione di comunicazioni decentralizzate Matrix \u00e8 presentata come un progetto che utilizza standard aperti e presta particolare attenzione alla sicurezza e alla privacy degli utenti. Matrix offre crittografia end-to-end basata su un algoritmo verificato Signal, supporta la ricerca e la visualizzazione illimitata della cronologia delle conversazioni, pu\u00f2 essere utilizzata per il trasferimento di file, l'invio di notifiche, la valutazione della presenza online degli sviluppatori, l'organizzazione di videoconferenze e la realizzazione di chiamate vocali e video. Sono supportate anche funzionalit\u00e0 avanzate come la notifica della digitazione, la conferma di lettura, le notifiche push e la ricerca lato server, la sincronizzazione della cronologia e dello stato dei client, diverse varianti di identificatori (email, numero di telefono, account Facebook, ecc.).<br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\"
