passing through gate ):That is, after JMP or call, follow the 48-bit full pointer (the 16-bit segment selects the child + 32-bit address offset), and the segment selects the child pointing to the segment descriptor, such a jump is called a direct (normal) Jump.Normal jumps do not cause a jump to the privileged level, that is, they do not cause CPL changes., See the following detailed description: The target is a consistent code segment:Requirements:C

DPL, RPL, CPL DPL is placed in the segment/gate descriptor, and RPL is located in the Selection Sub-, CPL is the CS. RPL that loads the visible part of the Selection Sub-CS Data Segment: The data segment is always the same segment. The data segment must meet the requirements of max (RPL, CPL) There is a metaphor: The Prime Minister (CPL = 1) can access the mayor (DPL = 3) in the name of the Governor (RPL = 2. Of course, in the name of the village chief (RPL = 4), it is estimated that no one

1. Change the program execution path to obtain the EIP; Obtain an EIPWhy EIP? The answer is simple, because the execution program needs to locate it for itself. If you have an understanding of the virus writing technology, do you know how the virus program locates? It is implemented using call/pop. Readers familiar with Assembly know that the call XXX command is equivalent to push EIP, jmp xxx, that is, the call command First pushes the next command

. OBJ According to the information obtained in the. textbss section, we can know that when incremental links are enabled, this space is used to store ILT tables.1.1.2 functions in DLL There are also some interesting symbols in the symbol table: 0002: 12724e2 _ getcurrentprocessid @ 0 004134e2 F Kernel32: kernel32.dll 0002: 12724e8 _ getsystemtimeasfiletime @ 4 004134e8 F Kernel32: kernel32.dll These functions should be implemented in DLL. Why is there a symbol table? In addition, each function h

"hitOpen crash dump "loads the saved files. The following is an example of using the trap handler to directly call kebugcheckex. After loading the memory dump file, windbg displays the following: Windbg shows that kebugcheckex is called by the self-trapping program kitrapoe and the trap token address is 0x8054199c. Now we use the "trap address" command to display the content of the trap token. Now we can see the status of all registers when an exception is throw

construct the real mode section in the protection mode to jump back to the real mode. When switching from the protection mode to the real mode, because each segment register is equipped with a segment descriptor high-speed buffer register, its content will be taken from the protection mode to the real mode, However, the content "format (in fact, it is the segment attribute in the real mode and cannot be manually modified in the real mode)" is the format in the protection mode, which does not ma

Before analyzing the MBR structure, let's take a look at the computer's boot sequence) Step 1. Enable and initialize the internal power supply, and wait for a short period of time to generate a stable current. If the motherboard chip and CPU receive an invalid current, a reset signal is automatically generated. Repeat Step 1 before the motherboard receives the power good signal from the power supply. Step 2. ExecuteCode. There is only one JMP comm
