What happened

In July 2015, the Qatar National Bank suffered a data breach which exposed 15k documents totalling 1.4GB and detailing more than 100k accounts with passwords and PINs. The incident was made public some 9 months later in April 2016 when the documents appeared publicly on a file sharing site. Analysis of the breached data suggests the attack began by exploiting a SQL injection flaw in the bank's website.

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. Freeze your credit. A credit freeze at the major bureaus is free and blocks new accounts from being opened in your name.
5. 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.
6. Watch for targeted phishing mail. A leaked home address makes postal and doorstep scams more convincing.
7. Reset security questions everywhere you used the same answers. Treat leaked security answers like leaked passwords — they rarely change and unlock account recovery.
8. Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
9. Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
10. 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.
