How can I check if my information was compromised in the Ashley Madison breach?

To check if one's information was compromised in the Ashley Madison breach, he or she should visit a website dedicated to checking if personal details have been exposed in data leaks. One such reliable service is "Have I Been Pwned?"—which securely allows individuals to enter their email address and see if it was included in the Ashley Madison leak or other data breaches. It's essential to use trusted services to avoid further compromising personal information. If one finds that his or her information was indeed involved in the breach, he or she should immediately change passwords and take steps to secure accounts, including enabling two-factor authentication where available.
