\nUtilizatorii care nu au f\u0103cut update la ultima versiune de Java \u015fi care au vizitat site-ul Yahoo.com \u00een ultimele 24 de ore au fost \u0163inta unui atac de tip malwertising (reclam\u0103 r\u0103u inten\u0163ionat\u0103). Reclama se afiseaz\u0103 cu prec\u0103dere utilizatorilor din estul Europei, unde Yahoo! are o cot\u0103 de pia\u0163\u0103 important\u0103, datorit\u0103 utiliz\u0103rii serviciului de mesagerie Yahoo! Messenger. Atacul produce o vulnerabilitate ce instala diver\u015fi viru\u015fi, printre care Zeus (malware financiar) \u015fi Dorkbot (un virus cu capabilit\u0103\u0163i de control de la distan\u0163\u0103). Virusul Zeus \u00eencearc\u0103 s\u0103 manipuleze tranzac\u0163iile online pentru a transfera sume de bani din conturile utilizatorilor c\u0103tre cele ale atacatorilor. \u00cen cazul infect\u0103rii cu Dorkbot, atacatorul planteaz\u0103 pe calculatorul victimei un backdoor, urm\u00e2nd s\u0103 decid\u0103 mai t\u00e2rziu cum va controla sistemul infectat.<\/p>\n
\n \u201cMetoda de distribu\u0163ie este extrem de popular\u0103 printre infractorii informatici, deoarece permite unui atacator s\u0103 \u0163inteasc\u0103 \u00eentregul public al unui site cu trafic ridicat, precum Yahoo, \u00een acest caz num\u0103rul victimelor va fi propor\u0163ional cu traficul. Chiar dac\u0103 portalul a identificat \u015fi eliminat reclama periculoas\u0103, utilizatorul deja infectat va continua s\u0103 simt\u0103 efectele virusului \u00een primul r\u00e2nd prin pierderi de bani \u015fi date sensibile, de aceea dezinfec\u0163ia rapid\u0103 e crucial\u0103\u201d, a declarat C\u0103t\u0103lin Co\u015foi, chief security strategist \u00een cadrul produc\u0103torului autohton de software de securitate informatic\u0103 Bitdefender.
\nAtacul func\u0163ioneaz\u0103 pe calculatoarele cu Java instalat. Pentru a se proteja de astfel de atacuri utilizatorii sunt sf\u0103tui\u0163i s\u0103 actualizeze imediat pluginurile web (Java, Adobe Reader \u015fi Flash Player) \u015fi s\u0103-\u015fi instaleze o solu\u0163ie antivirus performant\u0103.<\/p>\n
