As far as I know, they have been secured. Although one should always note and verify the authenticity of the website before proceeding. Always ensure you are on the right site. Cause I see some complains and that could be the cause too. Meanwhile, but address to my best of knowledge has been a secured site to create an address for this sole reason. I came to understand and confirmed that "not your private keys nor your wallet informations are transmitted, transferred or stored on their servers". This reduces the risk of losses or site is being compromised.
Yet it's very necessary to tread with extra caution.
