Email management provider Mimecast confirmed that the state-sponsored hackers who broke into its network as part of the SolarWinds hack to spy on its customers also downloaded source code from a limited number of repositories.
Mimecast said that the likely Russian hackers used one of its certificates to “connect to a low single-digit number of our mutual customers’ M365 tenants from non-Mimecast IP address ranges.” The hackers also accessed email addresses, contact information, and encrypted and/or hashed and salted credentials, Mimecast said.
