What happened
In May 2013, the Russian-language hacking forum YouHack suffered a data breach that was later redistributed as part of a larger corpus of data. The breach exposed 107k forum members' email addresses, usernames, IP addresses and MD5 password hashes, most of which were unsalted. Forum posts also contained email address and password pairs belonging to other victims, bringing the total to 7.2M unique email addresses.

What to do right now
- 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").
- 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.
- Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
- Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
- 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.
