Top 15 Prominent Wireless Hacking Tools to watch out for in 2018

Top 15 Prominent Wireless Hacking Tools to watch out for in 2018

Introduction

There was a time when people relied on broadband and mobile data packs for connecting to the internet. With the influx of IOT in our day to day life, the use of WiFi has increased many folds. Every house has almost five to six devices which require internet to work efficiently. Homes have now become more digitally connected with heavy usage of smart TV's, smart Ac's, smartphones, laptops, smart alarms etc. Three components related to WiFi have also gone to the next level along with all other advancements:

  • WiFi protocols: We are well aware that the use of WEP has depreciated due to security weaknesses. The protocol stack has developed over time from being highly insecure to the highest level of security possible.

  • Hardware technology: Both the endpoints that use the WiFi and the WiFi router have become advanced. Routers used to come with a single antenna having a small signal range. Now the routers have a bigger range, better signal strength and multiple antennas pointed in multiple directions so as to kill the blind spots.

  • Wireless attacks: Public WiFi, free WiFi and personal hotspots on the go have increased the wireless playgrounds that the attackers can target. Attackers can hack into the network and can monitor the traffic in that network or crack the password and use your network for free. Just check the wireless networks that the laptop catches and you can see an example right there!

Before we start digging deep into wireless hacking, let's get a few things straight: 

Hacking/attacking unauthorized wireless networks is illegal. The article does not encourage the use of the aforementioned tools for the criminal purpose. These tools are to be used only for educational purpose and to try on your own devices or network. Things are not going to be straightforward; wireless hacking is not as easy as shown in hacking movies.

What is wireless hacking?

The increase in WiFi usage has led to increased wireless attacks. Any attack on wireless networks or access points which provides substantial information is referred to as wireless hacking. This information can be in the form of WiFi passwords, admin portal access, authentication attacks etc. To understand wireless hacking, one of the most important things to understand are the protocols involved in wireless networks. Attacks are mostly made on the internal steps of the protocol stack. IEEE 802.11 specifies the standards for wireless networks; let us discuss some algorithms that are used in WiFi networks:

  • WEP (Wired Equivalent Privacy):  WEP uses a 40-bit key and a 24-bit initialization vector. It uses RC4 for confidentiality and CRC 32 for integrity. Since the initialization vector is of 24 bits, there is a high probability that the same key will be repeated after every 5000 packets. WEP is a depreciated algorithm due to the various vulnerabilities identified and the fact that it can be cracked very easily.

  • WPA and WPA2: WPA was introduced as a temporary solution for the devices that did not support WPA2. WPA has now been broken and depreciated. The WPA2 is considered to be the most secure to date. The tools discussed further in the article will also cover details on how to attack WPA and WPA2 but the success of an attack depends on the time and the computing power.

Attacking Techniques

  • WEP cracking technique: WEP uses a 40-bit key which is 8 characters long. Once enough data packets are captured, breaking this key should not take more than a few minutes. 

  • WPA/WPA2 cracking technique: Our devices have wireless passwords stored so that we do not enter the password on the same device again and again. The attackers take advantage of this by forcefully de-authenticating all the devices on the network. The devices will try to auto-connect to the access point by completing the 4-way handshake. This handshake is recorded and has the hashed password. The hashed password can be brute forced by using a rainbow table. 

  • WPS cracking: This technology uses an 8 digit pin to connect to the wireless router. Brute forcing the 8 digit pin will give access to the router. Various tools use various optimization techniques to increase the speed of this attack and crack the key in a couple of hours.
