Wireless Network Attack

Wireless networks have become an integral part of how we conduct our businesses. They ease many processes and help us get rid of the clutter caused by hundreds of wires yet keeping wireless networks safe poses some challenges.

Wireless technologies provide practical answers to our demands. They remove us from the mess generated by wires and cables while also being efficient and quick. However, it is a known fact that wireless networks are more susceptible to intrusions and attacks. In this article, we will explain types of wireless network attacks and how you can protect your organization from them. 

What is a wireless network attack?

With the widespread use of internet, we are able to conduct our business processes online and without being tied down by cables and wires. Wireless networks are one of the relatively new technologies brought to our lives by the internet technologies. They are easy to use, facilitate our business processes and mobilize our businesses. On the downside, wireless networks are much more vulnerable to attacks and intruders.

Commonly known as wireless network attacks, penetration and intrusion acts that target wireless networks pose serious threats. Wireless network attacks aim to capture the information sent across the network and/or intrude with the traffic of information. 

Packet Sniffing 

Networks are designed to facilitate and accelerate the traffic of information. In order to achieve this goal, the information is sent in packets across both wired and wireless networks. Due to the nature of wireless networks, these packets are sent through the air. As a result, it is very easy to capture them.

A great deal of traffic is sent through wireless networks, such as RTPSNMP or HTTP. The common feature of these is the fact that they are in plain text. Which means, one can easily read them with the help of free access tools like Wireshark. As a result, someone with malicious intentions can simply steal your passwords and similar sensitive information.

If you want to protect your wireless network against packet sniffing, you should invest in encryption solutions

Rouge Access Point 

Rouge access point refers to any unauthorized access point (AP) on a network. It can be created by an attacker or even a misinformed employee. Moreover, rouge APs make the entire network vulnerable to DoS attacks, packet captures, ARP poisoning and more.

You can use network access controls and network access protocols or introduce authentication processes to protect your organization. 

Jamming 

Network interference, commonly referred to as jamming, seeks to interfere with the network. Interference is usually always present because of the wireless features. Even a microwave oven or a set of Bluetooth headphones might create random interference. Most of the time, ill intended intruders combine jamming techniques with other methods like evil twinning. If you want to protect your organization, you should invest in a spectrum analyser, boosting the power of existing access points or using different frequencies. 

Evil Twinning

One of the most popular methods employed by wireless network attackers is creating an evil twin. To put it another way, attackers obtain a wireless access point and set it up to mimic the current network. In this manner, the ‘bad’ access point and legitimate access points are identical.

One of the easiest ways to stop evil twins from stealing the information of your organization is opting for data encryption, so that even if an intruder successfully creates an evil twin they cannot read your data.

Others:  

  • Misconfiguration Attacks: Such attacks happen when a Wi-Fi network is set to default configuration, and uses weak passwords & encryption protocols. Hackers use these weaknesses to compromise the network. 
  • Honeyspot Attack: It is very similar to evil twin attack where the malicious actors create a rogue access point and make the users share their credentials to connect to the network. When shared, they will use the credentials to gather information about the network and carry out further attacks. 
  • Ad-hoc Connection Attack: In an Ad-hoc Wi-Fi attack, the hackers use the trusted users who use Ad-hoc connection to spread trojan and malware into the network. The Ad-hoc connections are not secure and have weak encryptions. 

Countermeasures:

  • Always use WPA/WPA2 encryption.
  • Do not share your credentials.
  • Do not open untrusted emails.
  • Use IDS/Firewalls to filter the connections.
  • Change the default configurations.
  • Enable MAC-address filtering.
  • Use centralised server for authentication.
  • Do not connect to untrusted/public wifi hotspots.
