Assembly-Control transfer instruction JMP

Jump instructions are divided into three categories:First, unconditional jump: JMP;Second, according to the value of CX, ECX Register jump: JCXZ (CX is 0 jump), JECXZ (ECX for 0 jump);Three, according to the EFLAGS register flag bit jump, this too many.JMP Unconditional Transfer Instructions1, the direct short transfer within the paragraph 2, a direct near-transfer within the paragraph 3, within the paragraph near the transfer of 4, the direct transfe

Article 10 JMP $

In assembly, $ is used to obtain the address where $ is located. Therefore, JMP $ is an endless loop. Unless Interrupted, and the interrupted service program will be executed again. However, it should be noted that the returned address is still JMP $, rather than its The next statement. In JMP $ execution, the address of the

JMP & call & RET privileged transfer & Process Scheduling

JMP is not responsible for scheduling. It does not save any information, and it does not consider turning back. Skip this step.② Call, save EIP, and so on, so that the program can jump back. RET is the inverse process of call and the process of turning back. This is an inherent CPU command, so we do not need to save the information. Run the command directly.③ Privilege-level transfer within the same task, which is similar to ②, but you need to prepa

My understanding of the jmp selector: offset Model

Jmp selector: offset. The selector may indicate a segment descriptor or a gate descriptor. The cpu executes this command as follows: The above is my understanding of the jmp selector: offset execution process. In fact, the call selector: offset is similar, but the stack of cs and eip is added at the beginning and end, And the stack is output. (The arrow shown in the figure is a bit eye-catching. I can

Previous debugging methods

This anti-debugging method is different from the previous anti-debugging method.In the past, anti-debugging was based on the determination of the debugging personnel. Currently, powerful VMP and TMD methods are also used, the disadvantage of this method is that it is ineffective for a strong-willed, curious, or shake M (that is, if you give him a slap in the face, he also feels good from the heart. At present, we can all crack the VMP, TMD's norm, and prove the bottleneck of this anti-debugging.
