What is DNS spoofing? Stealing other people’s data can be termed hacking. In the case of DNS spoofing, malicious data that is obtained from another computer is transmitted into the DNS system, leading to confusing data readings, and ultimately, the crash of the system.
Wikipedia defines DNS spoofing in the following way:
“DNS spoofing, also referred to as DNS cache poisoning, is a form of computer security hacking in which corrupt Domain Name System data is introduced into the DNS resolver’s cache, causing the name server to return an incorrect result record, e.g. an IP address.”
Stealing other people’s data becomes an unethical act when it is done without permission. However, there are instances where DNS spoofing has no other purpose but to hack into computers and take down their functionality. It has been found that companies whose Active Monitoring systems are located outside of America are being hacked by malware and other hackers more frequently. Active Monitoring, in other words, is the monitoring of computer activity performed by employees on company premises. The employee activity is monitored using hardware and software, as well as through remote connections.
DDoS (Direct Target Attack) is another term used for DNS spoofing. A DDoS is an attack that overwhelms a victim server with traffic to the point that it cannot handle the traffic and crashes. When this happens, the attacker uses another server to launch another attack. Sometimes, legitimate system administrators perform a DDoS, thus misunderstanding the purpose of DNS spoofing. In this regard, the DNS servers are placed in a compromising position.
Stealing information from other computers that have already been infected with malware is known as DNS Swooping. In this method, hackers gain access to a victim’s computer by inserting fake DNS requests into the victim’s ActiveX browser. With the ActiveX page open, the hacker searches through the cache to see if any useful information can be found. If so, he gets the information and uses it to attack the targeted computer.
What is DNS spoofing?
To understand the answer to the question, you need to look at how DNS spoofing works. There are actually several components to this method of attack. There is the Active Directory service, ActiveSync, and other protocols in play. Basically, when an employee logs on, his IP address is recorded in the domain name system security protocol or dnssec.
Once the attacker gains access to the domain name system security protocol, DNS spoofing can begin. At this point, the attacker can do anything he wishes. He can post or change any number of web addresses in the search results. He can make his own website appear to be the very source of the requested information. Basically, anything goes once he is in control of the ActiveSync or ActiveDirectory connection.
Fortunately, there is a way to prevent DNS spoofing attacks. The problem lies in ActiveSync and ActiveDirectory. These are two important protocols that ActiveSync implements. Each of these services stores information about a website and ActiveDirectory also implements a directory of site links. This makes it very easy for the attacker to create his own websites that will eventually lead to an attack on your server.
To prevent DNS spoofing attacks, you can set up the ActiveSync application and set up your Active Directory settings so that the IP addresses of all employees are saved in the security area. You should also prevent ActiveSync and ActiveDirectory users from freely entering any of their addresses into forms and web browsers. Preventing browser injection is another way to prevent attacks. In general, you should avoid using free software and instead use commercial products that have been properly tested. It is always better to take advantage of services provided by well-known security companies.
One thing that you need to know is the way in which a hacker will use the free software to create his attack. Most of the free dns stubs will allow any IP address from the world to connect and access your server. Once he is able to establish himself in your system, he can then change the DNS server settings or even alter the files stored on the server. Since this is not a trusted way to update the information, you must make sure that you prevent the downloading of files from untrustworthy sources. If you are already facing a DNS spoofing attack, then you can still put the hacker’s data onto an offline disk so that he cannot use it as a gateway.
Another question that you might be asking is “What is dns spoofing? Harming of any server or client is called “DoS”. A DDoS is a distributed attack on a network of computers. It is caused by a massive number of users using their personal computers in what is called a “bot” to launch attacks. Since the server uses the IP address for all the names that are associated with each name, you will experience a large number of visitors that are launching attacks at the same time.
An important part of understanding what is DNS spoofing? The attack happens when a hacker copies the DNS Resolver keys that are stored on the names of your clients. It is vital that you have the right DNS resolver in place. Once the hacker has copied these keys, then you will have problems with getting your website to respond to connections.
