Practical Use of Burpy Plugin - Cracking the Encryption Algorithm of a WeChat Mini Program

Author: 0pening 1. Introduction Testing a certain WeChat mini program, without further ado, let’s start using BurpSuite to capture packets. However, upon capturing the packets, I noticed something was off 🤨. This application encrypts the parameters into bizContent and uses a signature parameter sign to prevent man-in-the-middle attacks on the data packets… not very honorable. … Read more

Performance Comparison of Different Encryption Algorithms in OpenVPN

We previously introduced that the forwarding performance of IPsec VPN varies with different encryption algorithms (using vSRX to test the performance differences of various IPsec VPN encryption algorithms), but does OpenVPN have this issue? First, we need to confirm the algorithm information used during the OpenVPN negotiation process. For the default configuration, the algorithm information … Read more
