In a new joint study recently released by Google, IBM, and Switzerland, it was found that more than four out of ten web users don't have the latest updates for their browsers of choice, and are likely vulnerable to attacks as a result.
It's probably not too surprising, but in the per-browser breakdowns, Firefox and Safari users do mostly keep up to date (83% and 65% running the latest versions, respectively). What is a bit surprising to me, given that users who opt for alternate browsers tend to be more security-conscious than the general internet populace, is that Opera came out with just over half of its users keeping up with patches. And finally, IE ranked at the bottom with a bit less than half of its users running the latest version, despite automatic updates having been standard on Windows machines for some time.
What about you guys? Are you running the latest version of your browser? If not, why not?
