There are times when we have problems with our wireless network and we simply don’t know what to do or where to start to find the solution. For this reason, the audit exists to help us find the problem and thus, solve it at the root. Wi-Fi ha-cking can be combined with auditing to provide a fairly robust wireless network security scheme. However, what applications can we use? This guide will recommend different applications, and a good part of them are compatible with Android mobiles to audit and ha-ck Wi-Fi. You can even take advantage of that mobile phone that you have not used for a long time.
Wi-Fi audits consist of a review of the Wi-Fi network in general, and, of course, also the security of the Wi-Fi wireless network itself. The most important aspects that are taken into account are the signal level and quality , the data transmission speed , how many devices are connected to the wireless network, and other aspects. Fortunately, Wi-Fi auditing applications in general are very easy and intuitive to use, so that in a few minutes, you will be able to have the information you need.
On the other hand, speaking of ha-cking Wi-Fi , the related activities are practically the same as those of auditing. However, these are distinguished by focusing on demonstrating the vulnerabilities and / or security holes that a wireless network has.
Free apps to ha-ck Wi-Fi and perform audits
Several of the applications that you will see below have essential prerequisites such as a mobile with Android in ROOT mode. So, if you are going to start ha-cking Wi-Fi, in the first instance opt for those applications that are easier and more intuitive to use.
Aircrack-ng
If you are a Linux user, this application will sound familiar to you, it is one of the best known and most reliable for ha-cking a wireless network. However, it is important to pay attention to all the requirements as they are all essential to a successful process. The most important requirements are: that your Android mobile is in ROOT mode, that it has compatibility for the “monitor” mode (monitor mode) , and a USB Wi-Fi adapter. Also, you need a computer with Ubuntu in its version 14 or higher. If you use another distribution, no problem. On the other hand, you will need a USB OTG adapter, specifically the micro USB or USB type C to USB female .
Now, why do I need my mobile to have support for monitor mode? So that it is possible to capture all data that is transmitted from the air in general, not only from the computer. This information capture is known as promiscuous mode. So first of all, look for information regarding whether your mobile is compatible.
It is good to know that there is no single definitive guide to launch Aircrackng on our Android. What makes it vary greatly in each situation, is the brand and model of the mobile, the version of the operating system, if it is an open distribution ( Cyanogen Mod , for example) or a customized version like that of brands like Samsung . The variables are multiple. Likewise, we have seen multiple tutorials from several years ago and there is evidence that somewhat old devices such as the LG G2 , the legendary Nexus 4/5/7 and HTC One were successfully tested.
We recommend visiting forums of sites such as XDA Developers , Reddit and StackExchange , in order to find tutorials tailored to each case and what to do if there are any problems.
dSploit
Applications like this and others present in the guide were created in order to detect vulnerabilities in wireless networks. This is one of the essential activities to ha-ck Wi-Fi. We must not forget that everyone is responsible for the use that one gives to these applications and that it is recommended to do so for educational and professional purposes.
In addition to the cracking and vulnerability detection capabilities, with dSploit it is possible to carry out actions such as alteration of data packets in transit, deciding which packets are finally sent over the network, data theft and display of passwords to then steal them. On the latter, if your focus is to know how much damage you can do to the devices that are connected to your network, you can do more: get full control of the victim’s device and permanently disable data packets.
As we see, these are all vulnerabilities already identified previously. So this application also gives us some awareness regarding the importance of connecting to secure networks. No matter how urgent our need to connect is, it is better to be cautious than to regret the loss of our personal data or the malfunction of our mobile.
Download the apk for free and try it out. In this case, it is also necessary to have your mobile in ROOT mode.
Wi-Fi Inspector
This application is used for both auditing and ha-cking Wi-Fi. However, this application is intended for professional purposes . If you are a professional in the field of computer security, an ethical ha-cker or if you work in IT, it is a very useful mobile tool. Any need for network control and monitoring can be covered with this application.
The main requirement to use Wi-Fi Inspector is that your Android mobile is in ROOT mode. Although it is similar to even some of the applications in this guide, it is known for being more intuitive. Some of the essential information that it displays are the number of connected devices, their IP address and what type of devices they use.
At the same time, you can limit the use of the network. That is, in seconds you can leave a member of your network without an Internet connection, even if they are connected to the network. Next, we share the shortcut to download it, if your mobile is in ROOT mode, you can try it right now:
WiFi Pass Key
This is another of the Android applications that you can use to ha-ck Wi-Fi, in order to challenge the vulnerability of your network. In addition to this, it is possible to create and share hotspots for other users to connect, this directly from the application. However, it does not have the ability to crack a network password, it simply shows you which networks have shared passwords or no security measures. Wi-Fi Pass Key is very easy to use and is available for download (APK) and installation at no cost. It does not need ROOT.
Reaver
With this app you will be able to obtain the passwords of Wi-Fi networks with ease. One of the advantages it has is the GUI (user interface) , which makes it much more user-friendly in general. What exactly can I do with Reaver? I can automatically detect any Wi-Fi router that supports WPS, enable and disable “monitor” mode.
If at the time of scanning networks, a WPA key is found that allows me to connect to a certain network, it does so automatically. For a more personalized use, it supports external scripts and advanced configuration options. This means that both beginner and advanced users can take advantage of the features of this application. Access this link to download the application and follow the installation instructions. It is one of the most recommended tools to start ha-cking Wi-Fi.
WeeNet
It is one of the most complete Wi-Fi audit applications we have found. It installs and starts up in a matter of a couple of minutes. The first thing you can verify when entering WeeNet, is to see certain information about the network to which you are currently connected. Also, you can know how many devices are connected and what type of devices they are. The example we share below shows that a mobile phone, a generic device (can be a smartwatch, for example) and a Chromecast are connected to the Wi-Fi network. Each of the devices can be pinged and look for the open TCP or UDP ports it has. Simply, you must click on the button next to each device connected to the network.
Another quick audit tool that will help you is the Network Diagnosis tool. In a few minutes you will have information regarding the state of the network in general. You will be able to know about the download speed, the neighboring networks that represent interference for the network to which we are connected, the speed and quality of the Internet signal, among other data. There are no time limits to perform these diagnoses.
This is another view that will be very useful: the list of available networks. Much more quickly, you will know what the signal level is. This is very helpful especially if we want to determine the actual location of the Wi-Fi router or if we would need an amplifier or repeater in order to provide better signal quality.
Another utility that WeeNet has is a network management and support tool. You just have to enter any IP address or website domain and then choose which of the basic commands to execute: ping , traceroute , what are the port numbers , whois and DNS .
One of the few drawbacks is that it has advertisements, so it is not very pleasant to use it like this. It has a fairly cheap premium version, so if you decide on this application, we recommend using it to the maximum with the paid version and goodbye to the ads. You can download this app directly from Google Play:
WPS WPA Tester
It is an application for auditing and ha-cking Wi-Fi that is aimed at checking the security of Wi-Fi networks, especially those that have very weak security protocols, such as WPS or WEP. After installing the application, at first glance you will get a list of the networks available around you, including the network to which you are connected. You will know the signal level and quality, the brand of the router, the channel where it is operating and the MAC address.
Whichever network you choose, a warning will appear before you start. Basically, it informs that the application was created for educational uses and that you are solely responsible for the end use that you give it. Of course, we should not use any such application for malicious purposes.
To go to the next step, you must click on “Next” and you will see the test options that try to violate the protection of our Wi-Fi networks. One of the tests we can do is try to connect to our network without the password, but with the WPS PIN that comes by default in the routers. Of course, depending on the brand and model, the combination of WPS PIN numbers may vary. That’s why it will try to connect by automatically inserting all possible PIN combinations.
However, it will not be possible to enjoy some of the benefits of this application because some are restricted by the requirement that the Android mobile must be in ROOT mode . You can download this application directly from Google Play:
Netcut
Without a doubt, this was what we needed. Nothing more unpleasant than realizing that our connection is very slow and that it is because of strangers who connect to our network. What distinguishes NetCut from the others is that you can very effectively leave those users strangers to your Wi-Fi network offline. It is a free application for Wi-Fi auditing and is compatible with multiple devices. However, the PC version is much more practical and does not require special permissions. You must download the latest version and the installation process is quick.
Keep in mind that, when installing, you must pay attention because two programs will be installed in total. Once you have finished, a window will open in your browser, it will be your administration interface.
The application is divided into three main parts: the one that corresponds to blocked users, the middle one that corresponds to users currently connected to the network, and the last one, on the right, which are the “main” devices of the network: the computer from where you manage Netcut and the Wi-Fi router.
In addition to being functional, it is very easy to be able to control what is connected to the network. We can customize the name of the device to better identify it, limit the bandwidth it can use (the oval button that you can slide) and schedule a time so that the user does not have connectivity. The latter is especially useful if we have to implement some parental control technique.
Now, the most important thing: completely limit connectivity. The image that we see below shows the connected device and we can notice the Wi-Fi signal icon .
You just click on that icon and leave no connectivity at that time. and the automatically logged in user profile on the left. The Wi-Fi signal icon turns red. Simply click on the red icon to return connectivity.
One of the lessons that we can take from NetCut is the importance of the security of the passwords that we put to our networks. It doesn’t matter if very few people live in your area, or if your neighbors spend little time at home. There will always be situations in which people connect to your Wi-Fi to carry out their activities.
Likewise, if we do not take basic security measures with our networks, we could be victims of attacks. Wireless networks, by nature, are more vulnerable than wired networks. So it is extremely important to use equipment that guarantees a high quality and safe user experience.
Fing
Another mobile application for Android that is free and quite functional. Although we see the occasional ad, it is not invasive at all and does not interrupt the normal use of Fing. At a glance, you will know how many devices are connected to the network, what type they are, the brand, the IP address and the MAC address .
By selecting one of the devices, more options are displayed. For example, you can run the ping and traceroute commands. You can see that the MAC address that we have below does not appear completely, this is because Fing has an option that allows masking MAC addresses . If you need to share information about the device, as in this case, you can do so with ease since the last identifying digits will not be visible.
Note: The Delete button does not mean that you are going to leave it without connectivity, it will simply disappear from your list in order to manage it.
Other network functionalities that we can have is a map where they show you the latest fall events in Internet access worldwide. Or, as in the example, you can opt for a kind of heat map that indicates live which are the problem areas.
There are several adjustments that we can make so that the application works as expected:
- Enable / disable device recognition (to show or not specific device data)
- Enable / disable reverse DNS lookup
- Night mode activation option
- Masking or not masking MAC addresses for privacy and other options
You can download the Fing app directly from Google Play:
Auditing and ha-cking Wi-Fi networks can be a lot of fun and highly educational, especially because of the amount of knowledge you gain from practice. We hope that these applications are very useful to you, tell us if you have used them before!
