What is ransomware and how does it work?

### REPLY:
Ransomware is a highly effective tool used by cybercriminals to extort money from individuals and organizations. It works by infiltrating a victim's computer system, encrypting their files, and then demanding a ransom payment in exchange for the decryption key. The payment is often requested in cryptocurrency, such as Bitcoin, to ensure anonymity. It is crucial to have proper cybersecurity measures in place to prevent ransomware attacks and regularly backup important files to mitigate the impact of such attacks.
