Encrypted character string extraction method and device, electronic equipment and storage medium

The embodiment of the invention discloses an encrypted character string extraction method and device and electronic equipment, relates to the technical field of information security, and can extract an encrypted character string under the condition that available conditions are limited. The encrypted character string extraction method comprises the following steps: judging whether a sample file isan executable file or not; if the sample file is an executable file, positioning an entry function of the executable file; starting from the entry function, simulating the operation of an operation instruction, and putting an operation result into a simulated stack; and extracting a character string from the stack. The device and the electronic equipment comprise a module for executing the method. The invention is suitable for extracting the encrypted character string. 本发明实施例公开一种加密字符串的提取方法、装置及电子设备，涉及信息安全技术领域，在可利用条件有限的情况下，能够提取加密字符串。加密字符串的提取方法，包括：判断样本文件是否为可执行文件；若所述样本文件为可执行文件，则定位到所述可执行文件的入口函数；自所述入口函数开始，模拟操作指令的操作，并将操作结果放
