Much as Che Guevara’s book Guerilla Warfare helped define and delineate a new type of warfare in the wake of the Cuban revolution in 1961, Cyber Guerilla will help define the new types of threats and fighters now appearing in the digital landscape. Cyber Guerilla provides valuable insight for infosec professionals and consultants, as well as government, military, and corporate IT strategists who must defend against myriad threats from non-state actors. The authors take readers inside the operations and tactics of cyber guerillas, who are changing the dynamics of cyber warfare and information security through their unconventional strategies and threats. This book draws lessons from the authors’ own experiences but also from illustrative hacker groups such as Anonymous, LulzSec and Rebellious Rose.
