The Integration of Web2.0 and Web3.0: New Challenges in Cybersecurity

Driven by the wave of digitalization, the intersection of Web2.0 and Web3.0 has become an inevitable trend. This integration brings new opportunities for the development of the internet, while also presenting unprecedented security challenges.

The emergence of Web3.0 is seen as a hope for building a more secure and transparent internet. It aims to address the long-standing issues of privacy and data control in centralized Web2.0 systems. However, as Web3.0 develops, its interactions with the Web2.0 network often occur in dangerous ways, providing fertile ground for new types of cyber security threats. If these potential issues are not controlled, they could undermine the security offered by Web3.0.

Despite many tech enthusiasts actively embracing Web3.0, the transition from Web2.0 to Web3.0 is not smooth sailing. In this process, newly emerging security vulnerabilities can easily be exploited by hackers and phishers. Therefore, to build a more secure digital ecosystem, Web3.0 must first prioritize and address the weak links left over from Web2.0.

Key Vulnerabilities at the Intersection of Web2.0 and Web3.0

Web2.0 and Web3.0 represent two fundamentally different approaches to internet data processing. Web2.0 relies on centralized servers and data collection models, concentrating power in the hands of a few large companies. In contrast, Web3.0 uses blockchain's distributed ledger technology to return data ownership to users, achieving decentralization of control.

However, these two systems are not completely independent; many Web3.0 applications still rely on the infrastructure of Web2.0, such as domain names, storage, and APIs. This dependency causes Web3.0 to inherit the centralization flaws of Web2.0 as well. For example, Web3.0 platforms that use cloud service providers for off-chain storage may also be vulnerable to server exploits. Similarly, Web3.0 platforms with Web2.0 interfaces are also at risk of phishing attacks and DNS hijacking.

Phishing Attacks: Web2.0 Vulnerabilities in the Web3.0 Environment

Phishing attacks have long been a threat in the Web2.0 environment. In Web3.0, the methods of attack are basically similar: attackers mimic the interface of legitimate platforms to deceive users into revealing their private keys or signing malicious transactions.

These attacks exploit the flaws of Web2.0, using means such as domain forgery and email scams to deceive users into believing they are interacting with legitimate decentralized platforms. For example, phishing attacks targeting DeFi platforms may use counterfeit Web2.0 websites to lure users and subsequently steal funds from their Web3.0 wallets. Therefore, the integration of Web2.0 and Web3.0 provides criminals with the opportunity to combine traditional phishing attacks with new technologies, posing a serious threat to users who mistakenly believe that decentralization itself can provide comprehensive protection.

The Transparency and Security Advantages of Web3.0's Decentralization

Despite the aforementioned risks, Web3.0 still brings hope for a safer internet through its decentralized technology and transparent framework. The blockchain, a pillar of Web3.0, is an immutable ledger whose tamper-proof capabilities far exceed those of traditional Web2.0 databases. At the same time, smart contracts eliminate the need for potentially vulnerable third parties, while decentralized identity solutions allow users to control their digital identities, effectively reducing the risk of phishing attacks.

In addition, the transparency of Web3.0 enables users to verify transactions and audit systems in real time, providing a level of security and accountability that is difficult to achieve within the opaque structures of Web2.0. By decentralizing control to multiple nodes, Web3.0 reduces the risk of large-scale data breaches commonly found in centralized systems.

Accelerate the Web3.0 application process and reduce cybersecurity risks

To reduce the new security risks arising from the overlap between Web2.0 and Web3.0, comprehensive decentralized systems must be accelerated. As long as Web3.0 still partially relies on Web2.0 infrastructure, it will continue to be subject to hybrid attacks that exploit the flaws of both systems.

The advantages of decentralized systems in enhancing security are obvious. For example, in the DeFi space, users can trade directly without relying on third-party platforms, thereby reducing the risk of third-party vulnerability attacks. Additionally, decentralized applications (Dapps) built on blockchain networks allow users to interact securely with the platform without the need to log in or avoid centralized data storage.

However, to realize the full potential of Web3.0, developers and industry leaders must commit to building decentralized infrastructure that operates independently of Web2.0. This means investing in the incubation of decentralized storage solutions, identity protocols, governance systems, and other related areas, all aimed at reducing the inherent risks associated with the current reliance on Web2.0, in order to create a safer digital environment.
