My attempt to prevent private key phishing.

As you're all probably aware, Ethereum wallets and Slack channels have come under some major phishing campaigns and they've worked - a lot of people getting their wallets drained, a lot of people complaining, and a lot of people just don't know why their address is now empty.

I've been chatting to the guys that run MyEtherWallet and we've come up with a solution to help mitigate the phishings to the common user - EtherAddressLookup.

EtherAddressLookup is delivered as a Chrome extension and does 2 main jobs;

Automatically links Ether addresses to your favourite blockchain explorer

Initially, I built this feature for myself. Whilst helping people who were new to the cryptocurrency world, I came across a lot of copy/pasted addresses with no link, and I was becoming a little tiresome having to open a new tab to my favourite blockchain explorer and manually search it - but the users of the extension are finding great use for it also.

We've also implemented the option to highlight matched Ether addresses for easier finding on a crowded webpage - which I personally use, and find it very useful.

Blocks the user from interacting with domains with malicious intent to steal private keys.

The recent events of many users being phished brought us to our next addition to the extension. We wanted a way to mitigate the impact of the phishes, and to do it we've built a blacklist of domains which the extension uses.

Since we are updating it a lot, the extension will grab a fresh copy of the blacklist every 3 minutes and cache the results in your LocalStorage.

When you land on a web page, the extension then checks the domain you're on to see if it's in the blacklist - if it is, then the extension will prevent you from interacting with the webpage by displaying an alert instead.

The feedback we've gotten back has been great, and we have plans for more features also.

You can download the extension to your Chrome browser here and receive updates automatically, or you can manually install it (though you won't get automatic updates).
