The vulnerability, Microsoft says, lets attackers gain the same user-rights as the current userthey could then install programs; view, change, or delete data; or create new accounts with full user-rights. There is a double whammy here for Indias banking sector and government agencies, who still make up around 70% of the 16% Windows users who are yet to upgrade from XP. With no support available for users on the now-retired operating system, these sectors are pretty much on their own when it comes to tackling the hackers. They can, of course, move on to a different browser, but it will take longer for them to change their mindsets regarding technology. It is not much of a problem for individual users who have anyway moved on to other options which give them much more than the Microsofts plain vanilla offering. With Internet Explorers biggest USP also taking such a hit, it remains to be seen how Microsoft gets people back on its browser.
