Description
Technical Field
The invention relates to the technical field of Internet of things, in particular to a networking equipment model detection method based on firmware analysis.
Background
With the development and popularization of the technology of the internet of things, a large number of intelligent devices are accessed to the internet, online internet of things device search can be achieved by using famous device search engines such as Shodan, Zoomeye and the like, the Shodan device search engine can identify devices including network cameras, printers, routers, traffic lights, intelligent home devices, industrial control systems and other networking devices, about 5 networking devices and services can be searched on the internet every month, unlike Shodan based on NMap scanning software, Censys uses ZAp scanning software based on stateless requests, can more quickly scan the whole internet to search all networking devices and collect relevant information, and returns a total report of configuration and deployment information of related resources (such as devices, websites and certificates); similar search engines exist in China, such as FOFA and zoomEye (the eye of Zhongkui), ZoomEye can lock a vulnerable area of a network space by mapping the global network space and combining equipment vulnerability information, network management is carried out in time, and national network defense capability is improved; zoomeye provides an API interface for research institutions, supports secondary development, can be used by researchers to obtain interested target equipment IP lists, has similar FOFA functions to Zoomeye, and can also search network components and equipment from different dimensions, such as regions, port numbers, network services, operating systems, network protocols and the like.
For model detection of internet-of-things equipment, the IP addresses of equipment of specific manufacturers and models can be searched by using equipment search engines such as Shodan, Zoomeye and the like as a search webpage, the technical principle is that the models of the networked equipment are identified by judging whether flag information of ports of the networked equipment contains character strings representing the models of the equipment, namely, common ports of all IP addresses of the whole internet are detected by using a web crawler, and responded flag information is stored, if the flag information contains text information representing the models of the equipment, the models of the equipment can be identified and found by the equipment search engines, but the method has the following problems:
1. missing reports exist: some devices do not include text information indicating the model of the device in the port flag information, and the device cannot be identified by the device search engine, so that a false negative exists. For example, when an existing search engine searches for a router of type RV110W produced by Cisco, and the keyword "RV 110W" is input, no result is obtained, because the character string of "RV 110W" is not included in the returned flag information when the open port of the router is accessed.
2. False alarm exists: when the DIR-815 is used as a keyword to search, the homepage of the website contains a character string of the DIR-815, so that the device search engine can feed back the IP address of the website as the IP address of the device of the model to a user, and false alarm occurs.
