The principle of war dialers is simple, first of all, it uses ascending or random way to dial a series of phone numbers, once found hidden modem can dial into the system, and can crack easy to guess password. War dialer for PCs with no password and remote control software. This is often the case with the connection between a company's staff's computer and its corporate system. There are a lot

This article analyzes the startup of the Linux-Android system. The following article focuses on the analysis of the functions before start_kernel () is called during Linux Startup, at the same time, I also gave an overview of the Code flow after the function start_kernel (). I hope that the topic on Linux-android startup can be continued. Haha.
