Ransomware is malware that commonly encrypts files so their owners cannot use them, then demands payment. Some attackers also steal data and threaten to release it. Paying does not provide a reliable recovery plan.
Quick example
Your documents suddenly will not open and a note demands payment for a decryption key. Some attacks also threaten to publish copied files.
Why it matters
Ransomware can interrupt work and make recovery expensive. Payment does not guarantee that your files or data will be safe.
Do this next
Keep separate backups before an incident. If you suspect an active infection, disconnect the affected device from the network and seek trusted incident-response help before restoring files.
