Potential Threats of Web2 Underlying Security Vulnerabilities to the Web3 Ecosystem

In the current Web3 space, the threats posed by traditional cybersecurity vulnerabilities have not received adequate attention. This phenomenon stems mainly from two factors: the Web3 industry is still in its early stages of development, and the relevant technologies and security measures are still being improved; at the same time, existing cybersecurity regulations have prompted Web2 companies to strengthen their own security infrastructure.

These factors have led to more focus in the Web3 space on on-chain security and the security of the blockchain ecosystem itself, while there is insufficient awareness of more fundamental vulnerabilities, such as those related to system-level, browser, mobile device, and hardware security.

However, it is important to note that Web3 is actually built on the infrastructure of Web2. If there are security vulnerabilities in the underlying Web2, it could pose a serious threat to the entire Web3 ecosystem, especially regarding the security of user assets. For example, browser vulnerabilities or mobile vulnerabilities could lead to asset theft without the user's awareness.

There have been multiple real cases of digital asset theft exploiting Web2 vulnerabilities, involving Bitcoin ATMs, Chrome browsers, Microsoft Word, and Android systems. These cases demonstrate that the threat of Web2 vulnerabilities to digital assets is real, and its impact is not limited to individual assets but could also jeopardize exchanges, asset custody companies, and mining institutions.

Given the significant impact of Web2 on Web3, it can be said that without the underlying security of Web2, the security of the Web3 domain cannot be guaranteed. Therefore, security measures in the Web3 domain should not be limited to single methods such as code audits; more security facilities are needed, such as real-time detection and response to malicious transactions.

Security technology is directly related to user assets, and the ability to conduct security research is also an important indicator of a security company's level. As the saying goes, "Without knowing the attack, how can we know how to defend?" In-depth research on Web2 vulnerabilities is crucial for enhancing overall security.

In the future, the Web3 field needs to continuously strengthen research on underlying security technologies, while encouraging communication and collaboration within the industry to collectively work towards creating a more secure Web3 ecosystem.
