International Cybersecurity Experts Sherri Davidoff, Karen Sprenger & Matt Durrin Debut the Ultimate New Guide, Ransomware and Cyber Extortion: Response and Prevention

MISSOULA, Mont., Nov. 15, 2022 /PRNewswire/ — LMG Security, a full-service cybersecurity consulting firm, today announced the debut of a new book, Ransomware and Cyber Extortion: Response and Prevention, written by LMG Security’s cybersecurity experts Sherri Davidoff, founder and CEO, Matt Durrin, director of training and research, and Karen Sprenger, COO and chief ransomware negotiator. Ransomware and other cyber extortion crimes have reached epidemic proportions, and the secrecy surrounding them has left many organizations unprepared to respond. Drawing heavily on their own unpublished case library, Davidoff, Durrin, and Sprenger guide the reader through the process of responding to ransomware and cyber extortion, minimizing damage, investigating more effectively, and expediting recovery. Readers will also receive practical prevention tips, as well as valuable checklists.

“Ransomware and cyber extortion can be devastating. Every organization needs to know how to minimize the risk of these attacks through effective prevention and response,” said Davidoff. “We are excited to share our experience and advice on ransomware and cyber extortion, including real-world case studies, in this practical and actionable guide.”

Ransomware and Cyber Extortion: Response and Prevention provides actionable steps and checklists to help security teams act swiftly and effectively together, throughout the entire lifecycle—whatever the attack and whatever the source. The book is a must-read for everyone involved in prevention, response, planning, or policy: CIOs, CISOs, cybersecurity professionals, IT staff, incident responders, investigators, negotiators, executives, legislators, regulators, law enforcement professionals, and more.
