Introduction to BurpSuite Tools BurpSuite is an integrated platform for attacking web applications. It contains many tools and designs many interfaces for these tools to accelerate the process of attacking applications. All tools share a powerful and extensible framework that can process and display HTTP messages, persistence, authentication, proxies, logs, and alerts. BurpSuite can work efficiently with a single tool, including the following toolkit: Proxy-is a proxy server that intercepts HTTP/S, acting as a middleman between the browser and the target application, allowing you to intercept, view and modify the original data flow in both directions. Spider-is a web crawler that applies intelligent sensing. It can enumerate the content and functions of applications completely. Scanner [Professional only]--An advanced tool that, when executed, automatically discovers security vulnerabilities in web applications. Intruder-is a custom, highly configurable tool that automates attacks on web applications, such as enumerating identifiers, collecting useful data, and using fuzzing techniques to detect generic vulnerabilities. Repeater-is a tool that manually reissues individual HTTP requests and analyzes application responses. Sequencer-is a tool for analyzing unpredictable application session tokens and important data itemsUndertake. Yixin Model: Unsecured Guaranteed Model Yixin Company was established in Beijing in 2006 and then launched P2P Platform for Yiren Loan. Different from the auction, when the investor decides to lend the funds in his hand, Yixin selects the borrower for him from among the loan applicants. The interest rate of the borrower is decided by Yixin according to its credit review, and the profit of the enterprise mainly comes from the service fee. Yixin's model is more like a combination of housing agencies and Taobao. Housing agencies collect housing resources, then contact buyers and charge agency fees after the transaction. The specific operation process is as follows: Yixin will break up the lender's money and make a multi-person loan contract to the lender. When the money reaches the third-party account, the contract will come into effect. Although Yixin does not have a contract between the lender and the borrower, Yixin's third-party account holder acts as the debt transferor for lending and borrowing, that is, the third-party account holder becomes Yixin's lender first, and after Yixin selects the borrower, the third-party account holder transfers the creditor's rights to the real lender. For each borrower recommended by P2P credit service platform, the lender has the right to decide whether to lend to the borrower of Yixin portfolio; The borrower repays the loan every month, the lender can dynamically know the repayment, income and other information of each creditor's right every month, and the lender can get the principal and interest repaid in the second month. Of course, lenders can also choose not to collect money but to continue to look for the next borrower in Yixin. This model was initiated by Yixin.
