Maybe by checking through the js file looking for the socket url? Or is there an easier way? Yes, you can. It is a very difficult task for a human to notice subtle patterns in large amounts of binary data, however, us humans are very good at finding patterns in images. Reverse Engineering Binary Programs and Its Security Applications. For example, it’s essential to pay attention to other files that are stored near the one you need to reverse engineer and know what different data types look like in a hex editor. First raw chunk depicted in Figure 8. memory region. This project aims to develop techniques to reverse engineer functionalities and data structures of binary executables without any symbolic information.
