The investigation into the m00p malware-writing crew that began more than seven years ago is considered a model of how things can work. Some of its tactics would go on to become blueprints for other crews that have risen in their wake in the last few years. The crew was neither the most sophisticated nor the most successful group of its kind at the time it was dismantled. The cooperative effort among law enforcement agencies in the U.K. and Finland and security researchers in various countries also has served as a model.
