BlackMatter actors use a separate encryption binary for Linux-based machines and routinely encrypt ESXI virtual machines. Go a step further by regularly updating your passwords and enabling multi-factor authentication (MFA). BlackMatter then remotely encrypts the hosts and shared drives as they are found,” reads the statement.

Mozilla moves towards multi-factor authentication. In an article reported earlier by SecureWorld News, we covered Microsoft's new "passwordless" technology , which is actually multi-factor authentication (MFA). Now, we need to incorporate something called authentication that integrates with access on the other side.
