Hacker - Websense: un pericolo per le aziende il mancato aggiornamento di Java e FlashPlayer

WebSense ha adesso scoperto che solamente il 19% dei computer aziendali basati su Windows ha eseguito l'ultima versione di Java (versione 7.0 update 25) tra l’1 e il 29 agosto 2013.

Oltre il 40% delle richieste Java aziendali provengono da browser che stanno ancora utilizzando l'obsoleto Java 6. Come risultato, più dell'80% delle richieste Java sono soggette a due exploit estremamente conosciuti e sfruttati da parte dei malintenzionati. L'83,86% dei browser aziendali ha abilitato Java.
A completare il quadro sconfortante, quasi il 40% degli utenti non esegue le versione di Adobe Flash più aggiornata (il 25% delle installazioni di Flash risale a più di sei mesi fa, quasi il 20% a un anno fa e quasi l’11% a due anni fa).
