Kunyu - More Efficient Corporate Asset Collection

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.

0x01 Install

Need Python3 or higher support

git clone https://github.com/knownsec/Kunyu.git
cd Kunyu
pip3 install -r requirements.txt

Linux:
	python3 setup.py install
	kunyu console

Windows:
	cd kunyu
	python3 console.py

PYPI:
	pip3 install kunyu
	
P.S. Windows also supports python3 setup.py install.

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 <your zoomeye key> --seebug <your seebug key>

You need to log in with ZoomEye credentials before using this tool for information collection.

	btype <host/web> 				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.

Multi-factor query

Similarly, Kunyu also supports multi-factor conditional query related assets, which can be realized through ZoomEye logic operation syntax.

Feature Search

Through HTTP request packet features or website-related features, the same framework assets can be concatenated more accurately

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.

Encoding hash calculation

In some scenarios, you can use this command to perform common HASH encryption/encoding, such as BASE64, MD5, mmh3, HEX encoding, and debug in this way.

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.

Pocsuite linkage

In versions after v1.3.1, you can use kunyu to link the console mode of pocsuite3 for integrated use.

HOSTS head collision

Through the HOSTS collision, the hidden assets in the intranet can be effectively collided, and the intranet service can be accessed according to the ServerName domain name and IP configured in the middleware httpf.conf. This can be achieved by setting the local hosts file later, because the local hosts file takes precedence. The level is higher than DNS server resolution. Support reverse check through ZoomEye domain name library or read TXT file to get the list of domain names.

HOSTS cross collision

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.

8. Regarding the error when using pip install kunyu

The following error was reported when using pip install kunyu: File "C:\Users\风起\AppData\Local\Programs\Python\Python37\Scripts\kunyu-script.py", line 1 SyntaxError: Non-UTF-8 code starting with'\xb7' in file C: \Users\风起\AppData\Local\Programs\Python\Python37\Scripts\kunyu-script.py on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

solution: Modify the C:\Users\风起\AppData\Local\Programs\Python\Python37\Scripts\kunyu-script.py file and add # encoding: utf-8 at the beginning of the file.

Then save it and you can use it normally. The bug appears because there is a Chinese name in the user's directory path, which usually appears on windows.

9. Pocsuite3 module POC storage directory

When using the pocsuite3 module, if you want to add a new POC module, you can add a POC file in project directory/kunyu/pocs/.

10. Pocsuite3 module POC missing issue

When using the Pocsuite command linkage, if it is a packaged Kunyu version, the poc has been fixed. At this time, modifying the poc directory cannot add new modules. At this time, you can repackage it or use the project directory/kunyu /console.py Run kunyu to update the poc module in real time.

OVER $60 MILLION WORTH OF BITCOINS HACKED FROM NICEHASH EXCHANGE

Over $60 Million Worth of Bitcoins Hacked from NiceHash Exchange. Bitcoin mining platform and exchange NiceHash has been hacked, leaving investors short of close to $68 million in BTC.

As the price of Bitcoin continues to rocket, surging past the $14,500 mark at the time of writing, cyberattackers have once again begun hunting for a fresh target to cash in on in this lucrative industry.

Banks and financial institutions have long cautioned that the volatility of Bitcoin and other cryptocurrency makes it a risky investment, but for successful attackers, the industry potentially provides a quick method to get rich — much to the frustration of investors.

Unfortunately, it seems that one such criminal has gone down this path, compromising NiceHash servers and clearing the company out.

In a press release posted on Reddit, on Wednesday, NiceHash said that all operations will stop for the next 24 hours after their "payment system was compromised and the contents of the NiceHash Bitcoin wallet have been stolen."

NiceHash said it was working to "verify" the precise amount of BTC stolen, but according to a wallet which allegedly belongs to the attacker — traceable through the blockchain — 4,736.42 BTC was stolen, which at current pricing equates to $67,867,781.

"Clearly, this is a matter of deep concern and we are working hard to rectify the matter in the coming days," NiceHash says. "In addition to undertaking our own investigation, the incident has been reported to the relevant authorities and law enforcement and we are co-operating with them as a matter of urgency."

"We are fully committed to restoring the NiceHash service with the highest security measures at the earliest opportunity," the trading platform added.

The company has also asked users to change their online passwords as a precaution. NiceHash says the "full scope" of the incident is unknown.

"We are truly sorry for any inconvenience that this may have caused and are committing every resource towards solving this issue as soon as possible," the company added.

Inconvenience is an understatement — especially as so much was left in a single wallet — but the moment those coins shift, we may know more about the fate of the stolen investor funds.

Odysseus

"Odysseus is a tool designed for testing the security of web applications. Odysseus is a proxy server, which acts as a man-in-the-middle during an HTTP session. A typical HTTP proxy will relay packets to and from a client browser and a web server. Odysseus will intercept an HTTP session's data in either direction and give the user the ability to alter the data before transmission. For example, during a normal HTTP SSL connection a typical proxy will relay the session between the server and the client and allow the two end nodes to negotiate SSL. In contrast, when in intercept mode, Odysseus will pretend to be the server and negotiate two SSL sessions, one with the client browser and another with the web server." read more...
