Background of Shan Ge Slow Fog Security Team In recent years, the rapid growth of the project has led to a revolution in financial innovation. The project uses blockchain technology to provide decentralized financial services, such as loan transaction asset management, so that users can interact directly without traditional financial intermediaries. However, due to the existence of a certain fund scale and user base, the project has also become a potential target for hackers. Many project parties think that security is contract security, which is a wrong cognition because it also contains information such as domain name servers. This kind of phishing fraud gang has followed, especially the attack by social engineering. This year, the phishing gang has attacked the project party, hijacked the domain name by taking over the project party, injected malicious code into the front end to defraud the user's signature, and finally achieved the purpose of stealing assets. Under this background, this article aims to evaluate and analyze the basic security risks of the projects on the leaderboard. As a platform to provide project data and ranking, the projects on the leaderboard represent the most concerned in the market. Note and widely used service testing items and methods First of all, we divide the items into different ranges according to the ranking, and make statistics. We mainly collect the relevant information of the domain name corresponding to each item, and analyze the exposure of the domain name information source. Security is a technical extension used to enhance the security of the domain name system. Its main function is to provide a mechanism to ensure the data integrity, authenticity and authentication of the query. The following are the main functions of data integrity through the use of numbers. Signature technology signs data to ensure that it has not been tampered with during data transmission, which can prevent malicious attackers from tampering with the response, redirecting users to malicious websites or hijacking network traffic, data authenticity and authentication can verify the authenticity of the response, and ensure that the data comes from authoritative servers instead of malicious servers, which helps to prevent fraudulent attacks, in which attackers try to forge responses to deceive users to resist cache poisoning attacks, which can prevent cache poisoning attacks, that is, prevent attackers from inserting them into the cache. False records lead users to be led to malicious websites, and false records can be detected and rejected through digital signature verification. Enhancing security is one of the key infrastructures of the Internet, and the use on which many network activities depend can improve the security of the whole Internet and reduce the success rate of malicious attacks, thus enhancing the network security of users and organizations. In short, the role is to enhance the security through digital signature and verification mechanism to ensure the integrity and authenticity of query data, especially after opening. Verifying whether the authoritative server of the domain name really reduces the risk of domain name hijacking and fraud is helpful to improve the overall security and credibility of the Internet. In this test, scripts and third-party detection websites are used to detect whether the project domain name is correctly configured and effective. Examples are as follows: domain name registrar security issues. Domain name registrars are responsible for registering and managing domain names, and their security measures include protecting user accounts from unauthorized access and preventing domain names from being maliciously transferred or changed. And to ensure the security of domain name registration data, a secure domain name registrar usually provides two-factor authentication, regular security audit and strong privacy protection function. Using an insecure domain name registrar may lead to a variety of security problems, some of which include hijacking an unsafe domain name registrar, which may be vulnerable to hijacking attacks. Attackers can tamper with the response and redirect users to malicious websites, which may lead users to be deceived and exposed to phishing malware or other malicious activities. Cache poisoning in the dynamic risk Attackers can carry out cache poisoning attacks by providing false records to unsafe domain name service providers, which will cause unsafe servers to cache false data in their caches, thus affecting a wide range of users and guiding them to malicious websites. Unsafe domain name service providers may be vulnerable to middleman attacks. Attackers can tamper with data during the transmission of queries, which may lead users to receive false responses. Wrong server or exposure to the risk of malicious websites, the service is unavailable. If an insecure domain name service provider is attacked by distributed denial of service or other network attacks, its server may become unavailable, resulting in inaccessible websites and online services, lack of support, and the insecure domain name service provider may not provide support, which will increase the insecurity of the query and make users more vulnerable to fraud and other attacks. In short, the use of insecure domain name service providers may lead to security problems. Exposing users and organizations to various network threats, it is very important to choose reliable domain name service providers that provide strong security measures, such as support, to protect domain names and network security. The project party should carefully evaluate and select domain name service providers to ensure that the services they provide are safe and reliable. This test collects the corresponding and current examples of project domain names by using such service providers as follows: Traffic protection and security issues. Content distribution network is a service to optimize the performance and security of the website. Security measures to reduce delay and improve access speed by distributing website content at multiple nodes around the world include resisting distributed denial of service attacks, applying firewall protection to websites, and supporting content distribution network vendors with insecure data transmission and encryption, which may bring various security risks, some of which include data leakage. Unsafe vendors may not be able to protect the data hosted on their servers, which may lead to the disclosure of sensitive information such as customer data. Login credentials or sensitive documents can be used by attackers to obtain or steal these data. Man-in-the-middle attack attackers may try to carry out man-in-the-middle attacks with end users, which means that attackers may tamper with or monitor the transmitted data traffic to obtain sensitive information or spread malicious content. Services are unavailable. If vendors are attacked by distributed denial of service or other network attacks, services may be interrupted, resulting in inaccessible websites or applications, which will be available for business. And if vendors do not take adequate security measures to verify and audit the content hosted on their networks, malicious users may abuse it to spread malicious software, malicious scripts or other harmful content. Unsafe vendors may not provide sufficient encryption support to make data transmission vulnerable to eavesdropping, which may lead to data leakage and privacy problems. Security vulnerabilities can be exploited by attackers to invade the network and access sensitive data or control network resources. Legal and compliance issues some vendors may be located in different countries or jurisdictions. 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台
