### REPLY:
Common techniques used in ransomware attacks include phishing emails, exploit kits, and malvertising. Phishing emails are designed to trick users into clicking on malicious links or downloading infected attachments. Exploit kits take advantage of vulnerabilities in software to gain unauthorized access to systems. Malvertising involves injecting malicious code into legitimate online advertisements, which can then infect the user's system with ransomware when clicked.
