Ransom War

This timely book explores the alarming rise of ransomware: malicious software blocking users from their systems or data until they've paid money to regain access or to prevent the release of sensitive information. High-profile British examples of the twenty-first century have targeted national libraries and healthcare organizations; in the US, hackers of Pennsylvania's Lehigh Valley Health Network held patient data hostage—when their demands went unmet, they published topless photographs of women with breast cancer.
