Dear MetaMask Users,

There have been several instances of high-profile legitimate websites such as BTC Manager and Games Workshop that have had their websites temporarily compromised. This involves showing a fake MetaMask window on the page asking for user's seed phrases. MetaMask will never open itself in this way and users are encouraged to report these instances immediately to either our phishing blacklist or our support email at support@metamask.io.

Please read our full article on this ongoing issue at https://medium.com/metamask/new-phishing-strategy-becoming-common-1b1123837168.
