How does ransomware work and what are its impacts?

### REPLY:
Ransomware works by encrypting the victim's files, making them inaccessible until a ransom is paid. It often uses sophisticated encryption algorithms to ensure that decryption without the proper key is practically impossible. The impact of a successful ransomware attack can be devastating, as it can lead to the loss of sensitive and irreplaceable data, disruption of business operations, and financial loss. It is crucial to educate users about the dangers of ransomware and implement robust security measures to prevent and mitigate such attacks.
