"The fact that this company was cc'd on an email containing access to the Nevada voter registration database appears to be evidence of a breach within the Nevada Secretary of State's email system," Engelbrecht wrote.

At worst it could reveal a breach that gives a foreign power access to not only the State of Nevada's systems, but also to the email systems of anyone whom the State communicates with via email."
