Ransomware is malicious software that encrypts files or locks users out of their systems, demanding payment for decryption or access. It typically spreads through phishing emails, malicious attachments, or exploit kits. Ransomware seriously threatens data security, often resulting in financial loss and operational disruptions. Effective cybersecurity measures, such as regular backups and up-to-date security software, are crucial for protection against ransomware.
