Yandex Dump data breach: 1.2M accounts exposed
Severity: high · Patch status: no-fix-needed · Since 2014-09-12
In September 2014, news broke of a massive leak of accounts from Yandex, the Russian search engine giants who also provides email services. The purported million "breached" accounts were disclosed at the same time as nearly 5M mail.ru accounts with both companies claiming the credentials were acquired via phishing scams rather than being obtained as a result of direct attacks against their services. Exposed data: email addresses, passwords. The breach dates from Sep 7, 2014; Have I Been Pwned loaded it on Sep 12, 2014.
What to do
- If you had a Yandex Dump account, change its password and the password of any other account that reused it.
- Turn on multi-factor authentication wherever it is offered.
- Check whether your addresses are in this breach at https://haveibeenpwned.com.
- Expect targeted phishing that quotes the leaked details; verify any unexpected contact out of band.
