First, the Reverse debugging technology Anti-debugging technology is a common kind of counter detection technique, because malware always attempts to monitor its own code to detect if it is being debugged. To do this, the malware can check whether its own code is set to break the point, or directly through the system to detect the debugger. 1. Breakpoint In order to detect if its code is set to a breakpoint

The so-called rootkit is a type of tool frequently used by intruders. Such tools are usually very confidential and difficult for users to notice. Through such tools, intruders have established a way that can always intrude into the system or control the system in real time. Therefore, we use the free software chkrootkit to establish an intrusion monitoring system to ensure that the system is installed with rootkit
