What is ransomware?

Ransomware is a type of malicious software (malware) that encrypts a victim's files or locks them out of their system, demanding a ransom payment to restore access. Cybercriminals typically demand payment in cryptocurrencies to maintain anonymity. Ransomware can spread through phishing emails, malicious downloads, or exploiting system vulnerabilities. It poses significant risks to individuals, businesses, and government organizations by potentially causing data loss and financial damage. Preventative measures include regular data backups, up-to-date security software, and user education.
