I just received an email from Bittrex regarding Phishing scams on their users. For those that haven't read it yet, here is the context of their email:
There has been an increase in fraudulent sites and phishing scams targeting Bittrex users with the intent of obtaining usernames, passwords, and two factor codes.
To protect yourself;
a) When you want to visit the Bittrex site, type https://www.bittrex.com directly into the browser address bar and then bookmark the site. Only use the bookmark to visit the site.
b) Be vigilant when using links and check the full URL address before entering your credentials. The only real Bittrex site is at https://www.bittrex.com and our support site located at https://support.bittrex.com.
Do not deposit funds to a wallet address that you receive in email, Slack, or social media. Bittrex will never tell you to do this.
c) Bittrex actively monitors and takes down fraudulent sites that are maliciously or erroneously using the Bittrex brand. If you see one of these sites, please report it to us via twitter to @BittrexExchange.
