Microsoft Reveals Email Breach, Says Hackers Accessed User Data

"This unauthorized access could have allowed unauthorized parties to access and/or view information related to your email account (such as your e-mail address, folder names, the subject lines of e-mails, and the names of other e-mail addresses you communicate with), but not the content of any e-mails or attachments", Microsoft said in the email sent to customers.

The unauthorized access was recorded between January 1, 2019 and March 28, 2019, Microsoft says, but the company hasn't provided any specifics as to how the hackers managed to compromise the credentials of the support agent.

Microsoft says that a "limited subset" of consumer account where affected, and the hackers have now been stopped.

Though users' email login information was not compromised by the security breach, Microsoft is still recommending that its users reset their email passwords. As part of maintaining this trust and commitment to you, we are informing you of a recent event that affected your Microsoft-managed email account.

The company assured its users that it has immediately disabled the compromised credentials to prevent their use for any further unauthorised access.

Microsoft has offered contact information for its data protection officer to help possible hacking victims to better protect their email accounts.

An email sent out to affected users stated that intruders were possibly able to see a user's email address, the email addresses of those a user corresponded with, email subject lines, and folder names the user had set up, but not the actual email contents or any passwords. As a result, you may receive phishing emails or other spam mails.

In an email notification to some affected users on Saturday, Microsoft said it became aware of an issue involving unauthorised access to some customers' web-based email accounts by cybercriminals.

ZDNet understands that the incident only affected a small number of Microsoft Outlook users and that Microsoft has also increased detection and monitoring for the affected accounts, just to be sure there's no unauthorized access for those accounts.
