The Pyramid of Pain was first introduced in 2013 by David Bianco. Using the Pyramid of Pain, he strongly asserts that not all attack indicators (indicators of compromise) are of the same value to an attacker. He defines the Pyramid of Pain as the level of difficulties or pain an attacker faces to be successful with his objectives.
