Can you explain how ransomware works? Does it cause physical harm to a computer or just encrypt files?

Ransomware is a type of malware that encrypts files on a victim’s computer or network, rendering them inaccessible. It typically demands a ransom to provide the decryption key needed to unlock the files. Ransomware does not damage computer hardware; it encrypts data and files, making them unusable until the ransom is paid or alternative recovery methods are used. It operates by exploiting vulnerabilities in systems or tricking users into downloading or executing malicious files.
