Abstract

The embodiment of the invention provides an Internet of Things equipment component version information extraction method based on a VEX intermediate language. The method comprises the following steps:acquiring Internet of Things equipment firmware, and determining a component binary character string; determining a binary character string with version information of the Internet of Things device;if the binary character string with the version information comprises a component version name and a component version number, directly extracting the component version name and the component versionnumber as the component version information of the Internet of Things equipment; and if the binary character string with the version information comprises a component version name and a formatted character string, obtaining disassembly data for the formatted character string, converting the disassembly data into a VEX intermediate language code, and determining a component version number based onthe VEX intermediate language code. According to the method provided by the embodiment of the invention, automatic extraction of the component version information of the cross-architecture Internet ofThings equipment is realized, and the component version information extraction efficiency of the Internet of Things equipment can be improved.

Description

technical field [0001] The invention relates to the technical field of Internet of Things devices, in particular to a method for extracting component version information of Internet of Things devices based on VEX intermediate language. Background technique [0002] With the rapid development of network communication technology, the number of IoT devices is increasing year by year. At the same time, the number of vulnerabilities and threats related to IoT devices are also increasing year by year. [0003] Among them, the firmware of the IoT device is the system software running on the IoT device, and as the software that performs the functions of the IoT device, its security cannot be ignored. The binary components in the firmware of IoT devices are the basic software that performs the actual functions. Commonly used IoT device firmware vulnerability mining methods are all based on mining a certain function or a certain protocol in the device, and the software that implemen...
