Microsoft releases tool to protect customers against server attack

Hit by multiple hacking on its business email servers, Microsoft has released a new, one-click mitigation tool to help customers who do not have dedicated security or IT teams to apply key security updates.

Called 'Microsoft Exchange On-Premises Mitigation Tool', the security feature has been tested across Exchange Server 2013, 2016, and 2019 deployments.

"This new tool is designed as an interim mitigation for customers who are unfamiliar with the patch/update process or who have not yet applied the on-premises Exchange security update," the tech giant said in a statement late on Monday.

Reports have claimed that five different hacking groups (including China-backed hacking group called 'Hafnium') were attacking the business email servers of Microsoft.

Microsoft has already released an emergency patch for its Exchange Server product, the most popular mail server worldwide. All incoming and outgoing emails, calendar invitations and virtually anything accessed within Outlook goes through the Exchange server.
