When we look around today, we will observe that many people are connected to networks without using cables. This is always referred to as wireless networks. Because this is the new mode of connection to networks, it has become the target of hackers. They will want to hijack these networks in order to steal data. In this article, I
Attackers at times make use of different tools in order to listen to wireless broadcasts. They are able to sniff data that are passing through cables and listen to conversations that are been passed from one end to another. Some make use of this tools that exposed organisational data to threats. This is one of the threats that organisational networks faced.
#2 Data interception and modification
Another challenge being faced by wireless networks is the problem of data interception and modifications. Some of the data being passed through the cables can be hijacked and the information being exposed to third parties along the line. The Attackers are able to intercept a network and install a rogue computer which allows them to modify or delete data that are being transferred through the cables. This allow them to intercept communications between two legitimate parties.
#3 Denial of Service
Another thing that can happen when attackers attack wireless networks is that they can caused denial of service where legitimate users are not able to have access to internet service. Through this medium, they are able to jam the network with noise. They are also able to reroute networks to dead end and ensure that services are not available to legitimate users.
Spoofing is one of the activities that can be carried out when attackers hijack wireless connections. Under this they are able to steal wireless addresses and mac addresses. They can now use it to send messages that are intended to impersonate valid users.
Spoofing happens when you receive mails that seems to have come from a known source but it happens to be a farce. I might get a mail from the Central Bank but it was not sent by the Central Bank but someone who was impersonating them. This has been used to defraud many of their hard-earned money.
This happens when the so-called attacker was able to use the network connection of the company to access the internet. I have seen many instances where students of a particular university hijacked the network and open the network of the University so that it becomes free for all.
#5 Rogue WLAN
Another problem with wireless networks is that it can be attacked with rogue wlans. Here the attacker will be able to attack the network and install their own wireless network on the network without the knowledge of the owners. Most at times, they will be able to use this medium to steal data from the network.
