46% of crypto lost from exploits is due to traditional Web2 flaws — Immunefi

A new report from blockchain security platform Immunefi recommends that almost half of all crypto lost from Web3 exploits is because of Web2 security concerns such as dripped private keys. The report, released on Nov. 15, looked back at the history of crypto exploits in 2022, categorizing them into various types of vulnerabilities. It concluded that a complete 46.48% of the crypto lost from exploits in 2022 was not from wise agreement defects but rather from “facilities weaknesses” or issues with the establishing firms computer system systems.Categories of Web3 vulnerabilities. Source: ImmunefiWhen thinking about the variety of incidents rather of the value of crypto lost, Web2 vulnerabilities were a smaller part of the overall at 26.56%, although they were still the second-largest category.Immunefis report left out exit frauds or other frauds, in addition to exploits that happened entirely because of market controls. Due to the fact that of a security vulnerability, it just considered attacks that occurred. Of these, it found that attacks fall under three broad categories. First, some attacks take place because the smart contract consists of a style defect. Immunefi pointed out the BNB Chain bridge hack as an example of this type of vulnerability. Second, some attacks happen because, despite the fact that the wise agreement is developed well, the code executing the design is flawed. Immunefi cited the Qbit hack as an example of this category.Finally, a third category of vulnerability is “infrastructure weaknesses,” which Immunefi defined as “the IT-infrastructure on which a smart agreement operates– for instance virtual machines, personal secrets, etc” As an example of this kind of vulnerability, Immunefi listed the Ronin bridge hack, which was caused by an opponent getting control of five out of 9 Ronin nodes validator signatures.Related: Uniswap DAO debate shows devs still have a hard time to protect cross-chain bridgesImmunefi broke down these categories further into subcategories. When it pertains to infrastructure weak points, these can be brought on by a worker leaking a personal secret (for instance, by sending it across an insecure channel), using a weak passphrase for a crucial vault, problems with tw-factor authentication, DNS hijacking, BGP hijacking, a hot wallet compromise, or using weak encryption methods and storing them in plaintext.While these facilities vulnerabilities triggered the best amount of losses compared to other classifications, the second-largest cause of losses was “cryptographic concerns” such as Merkle tree mistakes, signature replayability and foreseeable random number generation. Cryptographic issues resulted in 20.58% of the total value of losses in 2022. Another typical vulnerability was “weak/missing gain access to control and/or input validation,” the report specified. This kind of flaw led to just 4.62% of the losses in terms of worth, but it was the biggest factor in terms of the variety of occurrences, as 30.47% of all incidents were brought on by it.

Other Questions People Ask

What does the report by Immunefi reveal about the 46% of crypto lost from exploits due to traditional Web2 flaws?

The Immunefi report highlights that 46.48% of crypto losses from exploits in 2022 stemmed from traditional Web2 security issues, rather than smart contract defects. These vulnerabilities are categorized as "infrastructure weaknesses," which include problems like leaked private keys and insecure IT systems. This finding emphasizes the need for improved security measures in the Web3 space to address these foundational flaws.

How do Web2 vulnerabilities contribute to the 46% of crypto lost from exploits according to Immunefi?

According to Immunefi, Web2 vulnerabilities accounted for 26.56% of incidents, making them a significant factor in crypto losses. These vulnerabilities often arise from poor security practices, such as weak passphrases or inadequate two-factor authentication. Addressing these issues is crucial for reducing the risk of exploits and protecting crypto assets.

What types of vulnerabilities are included in the 46% of crypto lost from exploits related to Web2 flaws?

The report categorizes vulnerabilities into three main types: design defects in smart contracts, flaws in code execution, and infrastructure weaknesses. Infrastructure weaknesses, such as compromised private keys and insecure communication channels, were particularly impactful, leading to the highest losses. Understanding these categories can help developers focus on improving security protocols in their projects.

What actions can be taken to mitigate the 46% of crypto lost from exploits due to Web2 flaws?

To mitigate losses attributed to Web2 flaws, organizations should implement robust security practices, including strong encryption methods and secure key management. Regular audits of IT infrastructure and smart contracts can help identify potential vulnerabilities before they are exploited. Additionally, educating employees about security risks and best practices is essential to prevent incidents caused by human error.

Why did Immunefi exclude certain types of fraud when analyzing the 46% of crypto lost from exploits?

Immunefi focused solely on attacks that resulted from security vulnerabilities rather than including exit scams or market manipulation. This approach allows for a clearer understanding of how traditional Web2 flaws contribute to crypto losses. By isolating these specific incidents, the report aims to provide actionable insights for improving security in the blockchain ecosystem.
