PositiveThe New York Times Book ReviewDudley and Golden dig deeply into the emotional and financial tolls on people like Gillespie, who insists on offering his services to victims at no charge ... Dudley and Golden do a brilliant job of tracing the back-and-forth between attackers and defenders, like the little taunts the criminals embed in their programs after earlier versions are thwarted ... Even as they draw out these competitive and sometimes comical dynamics, Dudley and Golden are highly attuned to the havoc ransomware can wreak ... But the book leaves other potential legal and regulatory defenses against ransomware underexplored, such as systematic targeting of cryptocurrency exchanges, botnet operators, hosting providers and internet service providers that facilitate ransomware and could potentially be leveraged to disrupt these attacks ... Instead of focusing on policy and institutional shortcomings, Dudley and Golden are most interested in the characters at the center of this fight.
