Kunyu(坤舆) - More efficient corporate asset collection

English | 中文文档

0x00 Introduce

Tool introduction

Kunyu (kunyu), whose name is taken from , is actually a professional subject related to geographic information, which counts the geographic information of the sea, land, and sky. The same applies to cyberspace. The same is true for discovering unknown and fragile assets. It is more like a cyberspace map, which is used to comprehensively describe and display cyberspace assets, various elements of cyberspace and the relationship between elements, as well as cyberspace and real space. The mapping relationship. So I think "Kun Yu" still fits this concept.

Kunyu aims to make corporate asset collection more efficient and enable more security-related practitioners to understand and use cyberspace surveying and mapping technology.

Application scenario

For the use of kunyu, there can be many application scenarios, such as:

• Forgotten and isolated assets in the enterprise are identified and added to security management.
• Perform quick investigation and statistics on externally exposed assets of the enterprise.
• Red and blue are used against related requirements, and batch inspections of captured IPs are performed.
• Collect vulnerable assets in batches (0day/1day) for equipment and terminals within the impact.
• Information on sites involved in new-type cybercrime cases is quickly collected and merged for more efficient research, judgment, and analysis.
• Statistic and reproduce the fragile assets on the Internet that are affected by related vulnerabilities.
• .......

0x02 Configuration instructions

When you run the program for the first time, you can initialize by entering the following command. Other login methods are provided. However, it is recommended to use the API method. Because the user name/password login requires an additional request, the API method is theoretically more efficient.

kunyu init --apikey  --seebug

OPTIONS

ZoomEye:
	page     				The number of pages returned by the query
	dtype <0/1>      				Query associated domain name/subdomain name
	btype  				Set the API interface for batch query

Use case introduction

Here we use the ZoomEye module for demonstration

User information query

HOST host search

Web host search

Batch IP search

Icon Search

When collecting corporate assets, we can use this method to retrieve the same ico icon assets, which usually has a good effect when associating related corporate assets. But it should be noted that if some sites also use this ico icon, irrelevant assets may be associated (but people who are bored with other people's ico icons are always in the minority). Support url or local file search.

SSL certificate search

Query through the serial number of the SSL certificate, so that the associated assets are more accurate, and services that use the same certificate can be searched. When you encounter an https site, you can use this method.

Associated Domain/Subdomain Search

Search for associated domain names and subdomains, and query associated domain names by default. Two modes can be set by setting the dtype parameter.

Seebug vulnerability query

You can query historical related vulnerabilities by entering information about the framework and equipment you want to find, but you need to note that only English is supported, and improvements and upgrades will be made later.

Setting parameters

When set page = 2, the returned results are 40. You can modify the page parameter to set the number of pages to be queried. Note that 1 page = 20/items. You can modify the value according to your needs to get more returned results.

The configurable parameters and the current values of the parameters are displayed through show.

Data result

All search results are saved in the user's root directory, and the directory is created based on the current timestamp. All query results of a single start are stored in an Excel format under one directory, giving a more intuitive experience. The output path can be returned through the ExportPath command.

0x04 Loading

​ In fact, there are still many ideas, but as an Alpha version, this is the case, and it will continue to be improved in the later period. I hope that Kunyu can be known to more security practitioners. Thank you for your support.

​ The tool framework has reference to Kunlun Mirror and Pocsuite3, which are all very good works.

​ Thanks to all the friends of KnownSec 404 Team.

0x05 Issue

1、Multi-factor search

ZoomEye search can use multi-factor search, dork:cisco +port:80 (note the space) can search all data that meet the conditions of cisco and port:80, if there is no space in between, it is the same search condition, it is that cisco is satisfied and the port is All data for 80. Kunyu's dork does not require quotation marks.

2、High-precision geographical location

ZoomEye gives privileged users high-precision geographic location data, but it should be noted that ordinary users do not have this function, so I hope you know.

3、Username/password login

If you use username/password as the initialization condition, the token will be valid for 12 hours. If you find that your search cannot return data, you may wish to info. If the session times out, the initialization command prompt will be returned. In most cases, we recommend that you use the API KEY method, there is no invalidation problem. This design is also for the security of your account and password. After all, the API KEY can be reset and the token will become invalid. However, with the account and password, it is possible to log in to your ZoomEye account.

4、Cert certificate search

It should be noted that, according to the normal logic, you need to encode the serial number of the target SSL certificate in hexadecimal to match the sentence search, but Kunyu only needs to provide the Domain address to search. The principle is to make a request to the target station to obtain the serial number and process it, but if your host cannot access the target that needs to be searched, it cannot be retrieved. At this time, you can also search with the sentence in the usual way.

5、Favicon icon search

ico icon search not only supports URL retrieval, but also supports local ico icon file search, which has better scalability and compatibility.

6、Query data save path

By default, your query data is in the Kunyu folder under the user directory. You can also use the ExportPath command to query the path in the console mode.

7、Autocomplete

Kunyu's auto-completion supports upper and lower case, command logging, etc., use Tab to complete, please refer to Metasploit for usage.
