"description":"Demonstrates sophisticated capability. An innovator has the ability to create and script unique programs and codes targeting virtually any form of technology. At this level, this actor has a deep knowledge of networks, operating systems, programming languages, firmware, and infrastructure topologies and will demonstrate operational security when conducting his activities. Innovators are largely responsible for the discovery of 0-day vulnerabilities and the development of new attack techniques."

"value":"Practitioner",
"description":"Has a demonstrated, albeit low, capability. A practitioner possesses low sophistication capability. He does not have the ability to identify or exploit known vulnerabilities without the use of automated tools. He is proficient in the basic uses of publicly available hacking tools, but is unable to write or alter such programs on his own."

"value":"Novice",
"description":"Demonstrates a nascent capability. A novice has basic computer skills and likely requires the assistance of a Practitioner or higher to engage in hacking activity. He uses existing and frequently well known and easy-to-find techniques and programs or scripts to search for and exploit weaknesses in other computers on the Internet and lacks the ability to conduct his own reconnaissance and targeting research."
