Security Digest

Fake MEV bots and Discord: The security nightmares of this week.


Two hot topics this week in the world of crypto scams that have arisen are fake MEV bots that are stealing money from investors, and scammers using Discord to gain access to your account and target the communities that you are a part of. So much is happening that we decided to combine both of these hot topics into one single security digest to keep you updated.

The MEV bot scam begins on Twitter where an influencer will Tweet, and a bot would immediately post a link as a reply in hopes that some poor soul would click it. The link is supported with a piece of text that talks about how a particular trading strategy worked, and how you can make money using the same strategy. Upon clicking the link, you will be directed to an unlisted Youtube page that has instructions to deploy your own frontrunning MEV bot - a frontrunning MEV bot detects when someone is placing an order on Uniswap, buys the token that the individual is trying to buy before the trade is executed, and sell the token to the original buyer at a higher price. The tutorial goes on to explain how one can deploy the same bot and provides code to deploy a smart contract, and deposit ETH. That’s where the magic happens - the second you deposit your ETH and run the contract, your money disappears and probably ends up in some North Korean hacker’s wallet.

Now, let’s talk about how to get rekt with Discord. 0xFantasy’s thread discusses how a project will approach you for a collab, or to test a mint site. They may even share a link to a fairly legit looking website. However, the link will contain random letters, and tend to be exceptionally long. When you click the link and enter the website, a pop-up would ask you to open a console tab and ask you to “eval” something. The image of the fake pop-up is attached below.


This “eval” statement will then steal your Discord token. So, how did this happen? When you click the link, the Discord website is opened and embedded into the website as an iFrame, and made invisible. The pop-up takes up the entire screen so it is the only thing that you can click on. The code that is run on the website is actually reading data from Discord, and in this case, will read your Discord credentials. Now, the attacker has a way to use your credentials to target the NFT communities that you are a part of.

So, how do you protect yourself from these type of attacks?

  1. If you don’t understand what you’re doing, don’t do it. If you have never before deployed a smart contract, or are unsure of the source of any link, don’t do anything. You can choose to verify with sources that you trust and are technical in the case you do want to proceed.

  2. If you believe your account has been compromised, reset your password immediately. Reseting your password changes the identification token for the service that you are using rendering previously stolen credentials useless.

  3. Constantly educate yourself. Web3 is at the bleeding edge of technology, although there is a lot of good, there is an abnormally larger amount of bad taking advantage of information asymmetry.

Map the NFT ecosystem with NFTScan


If you’re tired of looking through marketplaces for statistics on NFTs, boy do we have a solution for you. NFTScan feels a lot like Etherscan, or any traditional blockchain explorer. The only difference here is that, it is designed for NFTs. You can look through NFTs across 8 different chains - Ethereum, Solana, Polygon and BNB for example. NFTScan combines the best aspects of analytics across marketplaces, where you can see the best performing NFTs on a particular blockchain, but can also evaluate the best marketplaces as well.

Additionally, if you are interested in a particular NFT project, you can gain insights such as what the average holding time of the NFT, holder distribution in terms of how many wallets own how many NFTs and overall marketplace distribution which can help understand buyer interest for the particular NFT. Overall, NFTScan is a must use for anyone interested in NFTs.
