Byly zve\u0159ejn\u011bny nov\u00e9 podrobnosti o hackersk\u00e9m \u00fatoku na infrastrukturu decentralizovan\u00e9 platformy pro v\u00fdm\u011bnu zpr\u00e1v Matrix, o kter\u00e9m se informovalo r\u00e1no. Probl\u00e9mov\u00fdm \u010dl\u00e1nkem, kter\u00fdm se \u00fato\u010dn\u00edci dostali, byl syst\u00e9m kontinu\u00e1ln\u00ed integrace Jenkins, kter\u00fd byl napaden ji\u017e 13. b\u0159ezna. Pot\u00e9 byl na serveru s Jenkins zachycen p\u0159esm\u011brov\u00e1n\u00ed SSH-agera p\u0159i p\u0159ihl\u00e1\u0161en\u00ed jednoho z administr\u00e1tor\u016f, a 4. dubna \u00fato\u010dn\u00edci z\u00edskali p\u0159\u00edstup k dal\u0161\u00edm server\u016fm infrastruktury.<\/p>\n

B\u011bhem druh\u00e9ho \u00fatoku z\u016fstaly servery Matrix nedot\u010den\u00e9, zm\u011bny se omezily pouze na v\u00fdm\u011bnu adres v DNS.
