SAN FRANCISCO - Okta has discovered that hackers who breached its network two months ago stole information on all users of its customer support system – a scope far greater than the 1 per cent of customers the company had previously said were affected.  

The company, which manages user authentication services for thousands of institutions, notified customers in a letter Nov 28 that it has now determined the hackers downloaded a report containing data including names and email addresses for all clients in its customer support system.
