This suggests that spoof attackers have an ample amount of time to get their hands on important data. The price of overlooking these attacks can be catastrophic.

A considerable percentage of these attacks will have been spoof attacks. Contents [ hide ]. While ransomware caught the attention of organizations around the world during the WannaCry attack, many organizations underplay the damage that can be caused by a successful spoofing attack. Spoofing attacks are a tricky entity because they can occur in so many different ways. An email spoofing attack can be launched simply by replying to the wrong email!

In many cases, this is exacerbated as business owners make the dangerous misconception that their company is a small fish in a big pond. Unfortunately, nobody is safe from IP spoofing. Without the right training or equipment, a moderately-skilled attacker can sidestep your defense strategy and access your data at will. Having an awareness of all main forms of spoofing attacks and implementing measures to stay protected against them is the only way to safeguard your organization.

As mentioned above, spoofing attacks come in many different forms. Here is a list of spoofing attack types:. The attacker waits quietly on the network until they manage to crack the IP address. Once the IP address has been cracked, the attacker can intercept data in between the computer and the router. The end result is data in the hands of the attacker.

The attacker can then use IP addresses throughout your network against you to launch a denial-of-service DOS attack. There are many ways that you can detect an ARP spoofing attack. One simple way to check if an unwanted intruder is spoofing on your network is to open up the command line and enter the following:.

This command will show you the ARP table of your device. If two IP addresses are sharing the same MAC address then this means that there is an intruder on the network. An IP spoofing attack is where an attacker tries to impersonate an IP address so that they can pretend to be another user.

During an IP address spoofing attack the attacker sends packets from a false source address. These IP packets are sent to devices within the network and operate much like a DoS attack.

The attacker uses multiple packet addresses to overwhelm a device with too many packets. As one of the more popular types of spoofing attack, IP spoofing attacks can be detected through the use of a network analyzer or bandwidth monitoring tool. Monitoring your network will allow you to monitor normal traffic usage and recognize when anomalous traffic is present.

Catching IP spoofing attacks early is especially important because they often come as part of DDoS Direct Denial of Service attacks which can take the entire network offline. All endpoints on a network are identified by a MAC address and that identifier can also be faked by hackers.

The real MAC address on each device is unique and it is hard-coded onto the network card and so cannot be changed. However, through software, a fake MAC address can be inserted into outgoing communications. This is a MAC spoofing attack. MAC spoofing bypasses access control measures, gives a hacker the identity of a valid user, fools simple authentication checks, and can hide a rogue device on a network.

MAC spoofing operates within the network because routers rely on IP addresses to identify endpoints. However, MAC spoofing can be combined with IP address spoofing to enable attacks to be launched from remote locations. A network manager will still be able to view the traffic from that spoofed MAC address. An address that has been duplicated will show up as sending traffic from two different sources simultaneously.

Other telltale signs would be a company device seemingly connecting to the network from a different physical location on the network. Tools that would facilitate the detection of MAC spoofing include traffic analyzers and bandwidth monitors. Email spoofing attacks are where an attacker sends an email imitating another sender.
