Mimecast confirms SolarWinds Hackers compromised a digital certificate that encrypts data that moves between some of the firm’s products and Microsoft’s servers. The company is urging affected customers in the U.S. and U.K. to reestablish their connections to Microsoft products with newly issued keys. About 10% of the company’s customers or 3,900 users use this type of connection between Microsoft services. Mimecasts says most customers affected by this compromise have taken steps to disable the certificate and create new credentials.”]
