What happened

In May 2023, a credential stuffing list of 6.3M Polish email address and password pairs appeared on a local forum. Likely obtained by malware running on victims' machines, each record included an email address and plain text password alongside the website the credentials were used on. The data included 1.2M unique email addresses.

What data leaked

  • Email addresses
  • Passwords

What to do if you had an account

  1. Change the password. Change your password on this service. If you used the same password anywhere else, change it there too: attackers try leaked email and password pairs on other sites automatically. A password manager makes one unique password per site practical.
  2. Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
  3. Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
