What happened

In July 2015, the infidelity website Ashley Madison suffered a serious data breach. The attackers threatened Ashley Madison with the full disclosure of the breach unless the service was shut down. One month later, the database was dumped including more than 30M unique email addresses. This breach has been classed as "sensitive" and is not publicly searchable, although individuals may discover if they've been impacted by registering for notifications. Read about this approach in detail.

What data was exposed

• Dates of birth
• Email addresses
• Ethnicities
• Genders
• Names
• Passwords
• Payment histories
• Phone numbers
• Physical addresses
• Security questions and answers
• Sexual orientations
• Usernames
• Website activity

What to do right now

1. Change your password for this service now. And change it anywhere you reused the same password — attackers try leaked passwords on other sites within hours ("credential stuffing").
2. Turn on two-factor authentication. Even a leaked password is useless against an account protected by a second factor. Prefer an authenticator app over SMS.
3. Watch your card and bank statements. Set up transaction alerts, and consider a card freeze or replacement if the exposure included full card numbers.
4. Be alert for smishing and SIM-swap attempts. Treat unexpected texts and "carrier" calls with suspicion; add a PIN/port-freeze with your mobile carrier.
5. Watch for targeted phishing mail. A leaked home address makes postal and doorstep scams more convincing.
6. Reset security questions everywhere you used the same answers. Treat leaked security answers like leaked passwords — they rarely change and unlock account recovery.
7. Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
8. Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
9. Monitor the apps you use going forward. Clearly watches the breach record for the companies behind your apps and alerts you the moment one appears.
