Today, ransomware is causing dangerous operational failures, financial catastrophes, multi-million-dollar losses, and in some cases, deaths. Ransomware is even undermining the security of nation-states and becoming a contentious issue in international diplomacy. In Ransomware and Cyber Extortion: Response and Prevention, Sherri Davidson and her internationally renowned team of cybersecurity experts offer new insights and well-structured best practices for the entire lifecycle: prevention, detection, mitigation, remediation, and recovery.

Drawing on deep experience consulting with (and negotiating for) ransomware victims, the authors reveal how cyber extortionists now operate, and show how to limit damage, avoid costly mistakes, and reduce future risks. Their real-world case studies help you understand crucial complexities of ransomware response, and address issues ranging from avoiding reinfection to filing insurance claims.

Designed for easy use when you're under the most pressure, Ransomware and Cyber Extortion contains clear, visual tips for communication, time management, and preparation, cloud-specific issues, and much more. If you haven't faced a ransomware attack yet, count yourself lucky, and get this guide today—so you can prepare, before it's too late.
