On February 23rd, 2017, one of our service providers, CloudFlare, reported a serious security bug in their software. The bug caused approximately 1 in every 3,300,000 HTTP requests to leak sensitive data.
CloudFlare has fixed the bug in their software and reported that no Bitfinex data was present in the leaked data caches.
However, it is never a bad time to review your security processes and strengthen your passwords. The most important step you can take to secure your account is to enable two-factor authentication. Two-factor authentication (2FA) uses your phone or another device to add an extra layer of security for things like logging in and withdrawing funds.
Also please note that CloudFlare is a service provider for many other platforms and Bitcoin companies. Please take a few moments to check your other accounts and enable two-factor authentication on any that support this feature. You can update your Bitfinex password from the Account page and enable 2FA from the Security page.
