Twitter has killed a bug that had allowed some stalkers on the micro-blogging site to view protected tweets via SMS or push notifications.
It has taken the company four months to fix the flaw, which affected the selectively shared accounts of 93,788 users on the service.
Twitter said that the security blunder only happened "under rare circumstances".
All unapproved access to those accounts has now been blocked, the recently floated firm said.
While the scope of this bug was small in terms of affected users, that does not change the fact that this should not have happened. We’ve emailed each of these affected users to let them know about this bug and extend our whole-hearted apologies.
It added that a member of the white hat security community had helped Twitter "discover and diagnose" the gaffe. ®
