0x00 This article is dedicated to daily learning and note sharing to help everyone learn assembly language. Why learn assembly language? Because in red-blue confrontations, our tools are often detected and killed by some AV/EDR. Therefore, we need to counter AV, which is the evasion technique. To learn evasion techniques, we must start from the … Read more

Hello everyone, I am Xiao Feng Ge, and today we will explore how the C language controls hardware. The Design Philosophy of C Language The design philosophy of C can be summarized as “trust the programmer“. Unlike many modern programming languages, C imposes very few restrictions on the behavior of the programmer,it assumes that the … Read more
Place MASM in the D drive. Start DOSBox and enter mount c d:\masm and press Enter. This command mounts the D drive MASM as the C drive. Because when you first start, it is on the Z drive. Next, enter c: and press Enter; it has successfully started and is now usable. General-purpose registers: AX, … Read more

01 ARM Cortex-A9 Registers For the ARM Cortex-A9 processor, its registers mainly consist of two parts: general-purpose registers and system control registers. The general-purpose registers shown in the figure above are primarily used during code execution, allowing the CPU to execute code and perform related arithmetic operations. During debugging, the registers of particular interest are … Read more
