How to Protect Yourself in Web3
Stepping into the world of Web3 (the decentralized internet powered by blockchain technology) is like exploring a new city. It's full of potential, opportunity, and excitement. But, like any city, it also has its dangers. Cybercriminals and scammers are out there, looking to exploit vulnerabilities for their gain. Crypto scams have become all too common, with DeFi (decentralized finance) fraud and theft alone costing users over $10.5 billion in 2022.
To navigate this digital landscape safely, understanding the potential dangers and how to protect yourself is crucial. This article will highlight common scams in Web3, illustrated with real-life examples, and offer a comprehensive guide to fortify your security measures.
Ways to Get Robbed/Scammed in Web3
Phishing: Phishing is a scamming method where attackers trick you into revealing sensitive information, typically through a misleading email or a malicious website. For example, in one instance, an individual received an email that appeared to be from their wallet provider, asking for their private key, a crucial piece of information that lets you access and control your digital assets. Unfortunately, upon providing the information, they found their wallet emptied.
Malicious smart contracts: Smart contracts are like digital agreements that run on the blockchain. They automatically execute transactions when certain conditions are met. But not all of them are safe. Some are maliciously designed to exploit users and steal their assets. They may appear to provide a service, but hidden clauses in the code could lead to unexpected asset transfers.
Poorly-coded smart contracts: Even if a smart contract isn't intentionally harmful, poor coding can create vulnerabilities that can be exploited. A real-world example of this is the infamous DAO hack in 2016, where a loophole in the DAO smart contract was exploited, leading to the theft of 3.6 million Ether, a type of cryptocurrency.
Rug pulls: This is a type of scam where developers abandon a project and run away with the funds after users have invested. One notorious example is the DeFi100 scam, where investors lost about $32 million.
Bridge hacks: Bridges in Web3 are like digital highways that connect different blockchain networks, enabling users to move assets from one to another. When you want to use an asset (like a digital token) from one blockchain network (City A) on a different blockchain network (City B), you would need a bridge. This process involves locking up your asset in a specific wallet (like leaving your car in a parking lot in City A), and then a mirrored version of that asset (a rental car that looks exactly like yours) is created in City B for you to use. This is what we mean when we say assets are "bridged" between chains.
However, in this process, you surrender control of your original asset to the bridge service. This can potentially be risky. Why? Imagine a bridge filled with gold. It would attract a lot of attention, right? Similarly, bridges in the blockchain world can hold a lot of assets at once, making them attractive targets for hackers. And, unfortunately, not all bridges are safe. Some are poorly protected and can be hacked, resulting in the loss of assets. In other instances, the operators of the bridge themselves could act dishonestly and run off with the assets.
Best Practices to Avoid Getting Scammed
To navigate Web3 securely, follow these best practices, ranging from basic measures to advanced precautions.
Basic Security Measures
Never share your private keys and seed phrases: Your private keys and seed phrases are like the keys to a treasure chest, and if they fall into the wrong hands, your digital wealth could be stolen. Never share your private keys and seed phrases with anyone, under any circumstances. Not even with someone claiming to provide technical support. Authentic services will never ask for your private keys.
Use trusted wallets: Crypto wallets are like your home in the digital world, and you want it to be secure. Download wallets only from trusted sources such as official websites or app stores, and verify the publisher's authenticity before installing.
Keep your devices and software updated: While not a guarantee of security, maintaining updated device software can help protect against known vulnerabilities and threats.
Be wary of phishing attempts: Be cautious of emails or websites you interact with. Always verify the source of an email, especially ones with attachments. Furthermore, make it a habit to verify the domain name of the website you are on.
Advanced Precautions
Interact cautiously with smart contracts: Just like signing a legal contract without reading it, you wouldn't interact with a smart contract without understanding its safety. While we can't all be coders, there are ways to ensure the contract's safety without reading the code. Look for contracts that have been audited by reputable security firms - this is like having a legal expert go through the contract. But remember, even the best audits don't guarantee total security; it's about risk reduction, not elimination. Research the project and its team - if they're transparent about their work and identities, you're generally safer. Consider the community consensus too. A supportive and active community is usually a good sign. And remember, if something promises high returns and sounds too good to be true, it probably is.
Scrutinize bridge operations: Moving assets between blockchains can be a bit like crossing a bridge loaded with gold. It's a risky business. Some bridges have better security than others, but even the best can be vulnerable to hacking. Before using a bridge, understand how it works, who operates it, and what security measures it has in place. If you don't feel comfortable with the risk, don't use it.
