本文在研究著名*BO2K技术的基础上设计了一款远程控制*。该*程序能够通过客户端对远程主机进行控制和监视，服务端可以自动连接客户端。另外该*程序还包括远程文件操作（文件复制、拷贝、删除、下载、上传等），远程系统控制（重启、屏幕锁定、启动项管理），网络连接控制，远程进程管理和键盘监控等功能。最后本文实现了这一款*程序，并对其进行了测试。测试结果显示该*程序实现了所有的功能，能够对远程主机进行控制。-This paper studies the famous Trojan BO2K technology, based on the design of a remote control Trojans. The Trojans through client to control and monitor remote host, the server can automatically connect to the client. Also the Trojan also includes a remote file operations (file copy, copy, delete, download, upload, etc.), remote system control (restart, lock screen, Startup Manager), internet access control, remote process management and keyboard monitoring. Finally, we realized that a Trojan horse program, and tested it. Test results show that the Trojan implements all the functions that can be controlled on the remote host.
