What happened in Have I Been Pwned’s words
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.
