Today we are taking a look at a clone of PancakeSwap the most popular decentralized platform built on the Binance Smart Chain located at pancakeswvap.com. The domain is a lookalike of pancakeswap.com (which actually forwards to pancakeswap.finance the official domain you should be using.)

The front page is a fairly good clone of PancakeSwap including a modified version of the warning bar at the top of the page urging visitors to make sure the URL is correct, something we see on many websites these days to help visitors avoid scams.

The page asks us to choose and connect our wallet, following a normal process familiar to all web3 users, but let's see what is going on under the hood as everything is not as it seems.

Watching the phishing page load on the left side and the real PancakeSwap page loading on the right, we can see that some extra JavaScript is loaded on the phishing page from the location /drainer/ that we don’t see while the official page is loading, unless you were watching the browser traffic you wouldn’t see any difference between the two pages as this does not change anything that you can see in the browser window as this is happening in the background.

In most browsers you can open the developer tools by pressing the F12 key and browsing a website in order to inspect the traffic between you and the website along with other features useful to web developers such as JavaScript debugging.

Unfortunately I'm not yet familiar with the inner workings of web3 JavaScript libraries but it is safe to assume the code is used to drain the victims wallet of funds after presenting bogus signing requests that give the page more permissions to your wallet than would normally be requested by the official PancakeSwap website.

Both the registrar of the domain and the CDN provider used to mask the real host of the site have been notified via their customer support Twitter handles. I urge you not to visit any of the phishing URLs that I show in this article I visit there pages in a controlled isolated environment, you will be putting your funds at risk of theft.
