With many data breaches, the initial assessment of the impact is less than what the actual total ends up being. The opposite, however, is true with Facebook, which released a revised lower estimate for the number of people involved in its latest data breach.
On Oct. 12. Facebook said that only 30 million people were impacted by a data breach of its access token system, down from the 50 million the company originally estimated on Sept. 28. As a result of the breach, Facebook had actually reset the access tokens for 90 million users, out of an abundance of caution.
