Abstract

The invention discloses a method and a system for developing a shellcode of a *86 platform or a *64 platform fast. The method comprises the following steps: writing a function according to C language, and dynamically acquiring an application programming interface (API); writing the shellcode according to the acquired API; compiling the written shellcode with a compiler, so as to generate an EXE file of the *86 platform or the *64 platform; and extracting the shellcode from a code section of the EXE file with an extracting tool. As the writing of the shellcode is based on C language which is relatively high in level, the code developing speed is fast; and the API is acquired dynamically based on the function written according to C language, so as to adopt to the *86 platform or the *64 platform automatically. Therefore, a developing personnel can maintain shellcodes of the *86 platform and the *64 platform in a unified manner; and the shellcodes are easy to develop and maintain, and are unified, while complex functions can be realized easily.

Description

technical field [0001] The invention relates to the field of computer security, in particular to a method and system for rapidly developing x86 / x64 platform shellcode. Background technique [0002] In traditional techniques, shellcode codes are developed using assembly language. But using assembly language to develop shellcode code is very inconvenient when extracting code. Moreover, the assembly code of the x86 platform is different from that of the x64 platform, and two versions of the code need to be maintained. In addition, using assembly to develop shellcode is complex, error-prone, and requires high personnel. Developers need to spend a lot of energy on maintenance, which is not suitable for implementing complex functions. [0003] In actual use, when using buffer overflow vulnerabilities and other memory security vulnerabilities to test / attack, how to quickly develop and extract x86 / x64 platform shellcode codes, and how to quickly develop and extract the shellcode c...
