What is a significant threat associated with ransomware attacks like WannaCry?

The significant threat associated with ransomware attacks like WannaCry is primarily related to the concept of a data breach. In the context of ransomware, a breach involves unauthorized access to and control over an organization's data, often followed by the encryption of that data to hold it hostage until a ransom is paid. Ransomware can expose sensitive and confidential information to malicious actors, posing a serious risk to individuals and organizations alike.

Moreover, while ransomware does involve encryption of data, which is a pivotal part of how these attacks operate, the immediate concern for victims is often the breach of their data's security and privacy. This breach can lead to problems beyond just the inability to access files, including reputational damage and further exploitation of sensitive information if the ransom is not paid or the attack is improperly managed.

In summary, the threat posed by ransomware is not just about locking users out of their files but also about the potential for significant data breaches that compromise security and privacy.
