Matthew Meade is a cybersecurity expert with over 13 years of experience managing hundreds of data breaches. He discusses the growing threats of ransomware and data breaches. Ransomware locks users' computers until a ransom is paid, and hackers are increasingly using it successfully. Medical data is the most valuable type of data for hackers, selling for $50 per record. Meade advocates for proactive security practices like employee training, strong passwords, and incident response plans to prevent data breaches.
