Apple appears to have fixed a flaw in its password security just one day after a hacker announced a new tool that could conceivably breach the existing protection against "brute force" attacks on accounts by taking advantage of an exception. On January 1, a new tool called iDict emerged in a rough state that could bypass repeated password-attempt blocking due to an exception made for iPhones. On January 2, Apple closed that exception and began locking accounts iDict was being used against.
