Some of you must have expected that web3 comes with the advantage of cryptographic security with blockchain technology. Apparently, every new technology attracts opportunities as well as challenges. Web3 startups were successful in acquiring over $7 billion as an investment in 2022 in the face of bearish market conditions. The influx of capital and development of new projects has enhanced the value of web3 alongside exposing its vulnerabilities.  

The need to learn about web3 hack attacks emerges from the growing prominence of web3 security incidents. Market leaders such as Ethereum and BNB Chain reported major security incidents in 2022. The staggering growth in value of the web3 market has encouraged cyber criminals to come up with innovative scams and security risks. 

At the same time, web3 is a new concept, and users are slowly adjusting to the technology. Users are investing in cryptocurrencies, DeFi solutions and NFTs to capitalize on the benefits of web3. However, limited awareness of web 3.0 risks can make them vulnerable targets for scams and security breaches.

Most important of all, web3 transactions are irreversible, which creates difficulties in recovering assets lost to scams.

  • Celebrity Airdrops

The infamous Twitter hack scandal in 2020 is proof of how “celebrity airdrops” are not always what they seem to be. Scammers used fake accounts of popular individuals such as Barack Obama, Jeff Bezos, Elon Musk, and Joe Biden and popular companies such as Apple and Uber. The hackers offer cryptocurrency airdrops worth millions of dollars, generally in Bitcoin, in return for your Bitcoin.

On top of it, you could not reverse a cryptocurrency transaction.

  • Fake NFTs

Another popular approach for users to enter the web3 market points at NFTs or non-fungible tokens. Users are actively investing in NFTs through collectibles such as the NBA Top Shot collection, Twitter profile pictures with Bored Apes and NFTs for tickets to events. At the same time, concerns such as “Can Web 3.0 be hacked?” also draw attention to hackers compromising the NFT space. Considering the dominance of NFTs and their role in the web3 ecosystem, it is important to identify popular NFT scams. 

One of the common scams in the NFT space refers to forgery or fake NFTs. Scammers look for NFT projects which achieve significant growth in value within a limited period of time. Subsequently, the scammers can create copycat collections which resemble the original projects. An unsuspecting NFT enthusiast can assume that they have the chance to ‘ape in’ to a specific NFT collection at lower prices. 

Ultimately, the scammers can disappear with your money, and you would be left with a useless NFT collection. You can avoid NFT scams through comprehensive research on a specific NFT artwork or collection. It is also important to check the past transactions recorded for the NFT to verify credibility of the NFT.


  • Spoofing 

The list of web 3.0 risks also includes spoofing, which has been prevalent across social media platforms. Scammers use URLs, emails, text messages and live streams on social media websites to misguide web3 investors toward scam projects. Furthermore, technological innovations have enabled the possibilities of location and facial spoofing with ease. A spoof URL could look like a legitimate link for investing in a web3 project while it steals your private keys in the background. 

The most effective answer for ‘How to avoid web3 scams’ through spoofing would refer to a review of spoofing examples. Generally, scammers use the identity of a large trusted web3 company or web3 influencer in spoofing attacks. Assume that you received an email from Binance with a link for claiming rewards. Upon clicking the link, you land up on a website that looks similar to Binance and asks for your sign-in credentials. Once you enter the password, the scammer can access your Binance account and drain out your funds.

The threats of social media scams in web3 have increased exponentially with the introduction of the Twitter Blue subscription feature. How are you supposed to distinguish a verified account from the blue check, which anyone can buy for $8? Another example of web3 vulnerability in social media scams through spoofing refers to fake live streams.

Scammers don the hats of crypto and web3 influencers by spoofing content from credible sources and visually appealing content in YouTube live streams. How can you differentiate a credible YouTube influencer from a scammer? The answer would round up once again on the necessity of research. 

The best approach to avoid spoofing scams in web3 is to check the URLs, email addresses, and links you access. It is also important to remember that web3 projects do not require your seed phrases in any case. In the case of Twitter accounts, you need to check the time for which the account has been active. 

You must also verify the credibility and relevance of their posts for web3 before interacting with social media posts. Similarly, you can avoid spoofing web3 hack on YouTube by checking the number of videos on the channel. If you don’t find any videos on the YouTube channel the ‘influencer,’ hit the “Home” button immediately.

  • Rug Pull Scams

The outline of web3 scams would be incomplete without referring to rug pulls, which are a type of exit scam. Rug pulls are more common in the domain of NFTs and DeFi. Web3 offers flexibility in creating new decentralized projects with new tokens and freedom from intermediaries for financial transactions. 

Scammers can use this as an opportunity to exploit unsuspecting victims. Hackers could create a crypto token and list it on decentralized exchanges without any background check. Apparently, almost 117,000 scam tokens robbed billions of dollars from investors in 2022. 

The premise of rug pulls scammers convincing investors about the legitimacy of a project and its potential for the future. Scammers can present a DeFi project or NFT project as a promising one with an appealing website and create roadmaps for showcasing that the project would have a sustainable future. Once investors start investing their tokens in the project in return for native tokens of the project, the price of the native token would increase. When the native token price reaches a peak, the scammers will disappear with the money of investors. 

The web3 vulnerability with rug pulls is also evident in the case of NFTs. Scammers could create copycat collections of popular NFT projects. For example, a fake collection, Mutant Ape Planet, copied the Mutant Ape Yacht Club collection and robbed $3 million from buyers. 

The consistent improvements in vetting mechanisms for DeFi and NFT projects have opened up new prospects for safety against rug pull scams. Try to avoid web3 projects which cannot offer clear details about their founders and contributors. Take a look at the project’s whitepaper and verify whether they have passed a successful smart contract audit and KYC verification.

  • Pump and Dump Scams

Pump and dump scams are a variant of rug pull scams. The difference between pump and dump scams is the fact that influencers use such scams. Popular influencers, as well as token creators, could buy a specific cryptocurrency at a low price. The next step in such web 3.0 risks is the promotion of the token bought by the influencers. 

Influencers would convince their followers that the specific cryptocurrency is the next big thing in web3. Once investors start purchasing the cryptocurrency, the increased trading activity would inflate or ‘pump’ the price of the token. After a certain point, the influencer sells their cryptocurrency holdings at the peak price or dumps their investment. 

The unexpected exit of the influencer from the market results in a significant drop in the token price. Ultimately, the investors would have to bear the losses on a cryptocurrency that never had any potential in the first place. How can you ensure safety from a web3 hack through pump and dump schemes? 

You can find the answer by overcoming the fear of missing out on an exciting opportunity. Take your time in reading the documentation of a specific cryptocurrency, NFT or DeFi project before investing. You should maintain a strict focus on research irrespective of the aggressive marketing of certain crypto tokens by influencers.
