I wrote about the EOSGas phishing campaign here:

They would now like people to install their wallet (which is weird since they are only an ERC20 token so metamask would work fine). In other words they would like to install malware on your computer, which will probably be used to mine some kind of cryptocurrency. Scary thing is this above email didn't get blocked by Gmail's spam filter.
