A Microsoft Outlook breach that was disclosed on Friday is thought to be much larger than previously said, a new report found. A Microsoft email-platform breach is reportedly much worse than previously thought, now impacting a large number of Outlook, MSN and Hotmail email accounts. Microsoft said it notified the majority of those impacted that bad actors would not have had unauthorized access to the content of e-mails or attachments. Microsoft Outlook has been marred by vulnerabilities over the past year, including a patched bug that allowed attackers to steal victims Windows account password.
