The development of electronic commerce
The earliest e-commerce is the traditional EDI (Electronic data interchange, electronic exchange). In the the late 1960s, the concept of EDI was introduced almost simultaneously by Europe and the United States. The early EDI was done by direct communication between two business partners, and the deve

is not running in the compiler environment and does not include to declare functions, there is no function table for the application. Therefore, shellcode needs to find its own API function address and then forcibly call it.(1) Find the kernel32.dll base address:The APIs used in the shellcode are generally unrelated to the user interface, because it is used in kernel32.dll to do bad things. Therefore, we must first find the base address of kernel32 to further find the specific address of each A

, that is, taking the pixel (x, y) as the center, to (x-radius, Y) and (x + radius, Y) after the pixels are multiplied by weights, the new pixels are obtained and written to the corresponding points on the target image.
The process ends.
Since the above processing process only performs a "Ten" operation on each pixel of the image, the operation on each pixel point is greatly reduced, and the greater the fuzzy length, the more reduced. As mentioned above, the Q = 3 and r = 5 Fuzzy Operations only

the kernel shellcode and the user shellcode. The kernel shellcode is responsible for returning and executing the user shellcode. The user shellcode is a common function. You must add the firewall-based code. The following is the kernel shellcode Code, which does not provide complete shellcode, because first, it is only for technical research, but not to be used by people who do not know nothing about the technology but only want to destroy it.
