What should affected users do?
In general, affected users should:
Change Your Password: Immediately update your password for the breached account. Make sure the new password is strong and unique, not previously used on any other platform.
Reset Passwords for Other Accounts: If you've used the same or similar passwords for other online accounts, reset those as well. This is crucial as attackers often try using stolen passwords on multiple sites.
Enable Two-Factor Authentication (2FA): Activate 2FA on the breached account. Consider enabling this additional security feature on all other important online accounts to reduce the risk of unauthorized access significantly.
Monitor Your Accounts: Monitor your accounts for any suspicious activity. If you notice anything unusual, report it to the appropriate authorities and financial institutions.
