On April 1, 2015, U.S. President Obama signed an Executive Order, "Blocking the Property of Certain Persons Engaging in Significant Malicious Cyber-Enabled Activities".  The Order allows for the imposition of sanctions on individuals and entities who are determined to be responsible for or complicit in malicious cyber-enabled activities that result in enumerated harms that are reasonably likely to result in, or have materially contributed to, a significant threat to the national security, foreign policy, or economic health or financial stability of the United States.

In a particular manner and for the purposes of the Executive Order, malicious "cyber-enabled activities" include deliberate activities accomplished through unauthorized access to a computer system, including by remote access; circumventing one or more protection measures, including by bypassing a firewall; or compromising the security of hardware or software in the supply chain.
It is anticipated by the U.S Government that regulations to be promulgated will define “cyber-enabled activities" to include any act that is primarily accomplished through or facilitated by computers or other electronic devices.
