Security researchers revealed late Friday that iOS's validation of SSL encryption had a coding error that bypassed a key validation step in the Web protocol for secure communications. As a result, communications sent over unsecured Wi-Fi hot spots could be intercepted and read while unencrypted, potentially exposing user password, bank data, and other sensitive data to hackers via man-in-the-middle attacks. Secured Wi-Fi networks, such as home and business networks with encryption enabled, are not affected.
