Those of you who use any Apple products should take steps to fix a major security flaw that has been exposed. This flaw implicates a breakdown in its SSL protocols and so enables a third party to intercept communications between you and any site that you visit. Apple has issued patches to fix this for its iPad and iPhones and you should immediately install them by going to Settings->General->Software Updates.
Those with Mac computers using OSX are also vulnerable and although Apple says that a patch to fix that will be issued soon, it has not done so yet. Hence you should not use the browser Safari to interact with sites that use your sensitive information, with which you have any financial dealings, and that require passwords (such as banks and other companies) until this fix arrives. You can still use Firefox and Chrome.
