The US Federal Bureau of Investigation (FBI) has sent last month a security advisory to private industry partners about the rising threat of attacks against organizations and their employees that can bypass multi-factor authentication (MFA) solutions. The point behind two-factor authentication is that it uses unique security tokens that only the user who is trying to access a particular account is supposed to have.
