What is DNS hijacking

What is DNS hijacking?

DNS hijacking is a process in which an individual redirects queries to a domain name server (DNS).

DNS hijacking is the process by which an individual redirects a query to a domain name server (DNS).

It may be accommodated through the use of malicious software or unauthorized modification of a server.

This can be done through the use of malicious software or unauthorized server modifications.

Once the individual has control of the DNS, they can direct others who access it to a web page that looks the same, but contains extra content such as advertisements.

Once individuals have control over DNS, they can direct others who access it to web pages that look the same, but contain additional content such as ads.

They may also direct users to pages containing malware or a third-party search engine.

when they visit a web page that no longer exists.

when they visit a webpage that no longer exists.

Many claim this is to improve the users experience; however, this can also be another great source of extra revenue since they control the site and get paid off any advertising clicks.

What is Packet injection

Packet injection (also known as forging packets or spoofing packets) is a computer networking term that references to the process of interfering with an established network connection,

Injection packets (also known as forging packets or spoofing packets) are computer networking terms that refer to the process of interfering with an established network connection,

by means of constructing packets to appear as if they are part of the normal communication stream.

by building packages to appear as if they are part of a normal flow of communication.

The packet injection process allows an unknown third party to disrupt or intercept packets from the concerned parties that are communicating, which can lead to degradation or blockage of users' ability to utilise certain network services or protocols.

Packet injection is commonly used in man-in-the-middle attacks and denial-of-service attacks.

What is Clickjacking Attacks

What is Clickjacking

Clickjacking, also called a UI Redress Attack, is when a hacker uses multiple opaque layers to trick a user into clicking the top layer without them knowing.

Clickjacking, also called UI Redress Attack, is when a hacker uses multiple opaque layers to trick users into clicking on the top layer without them noticing.

This the attacker is “hijacking” clicks that are not meant for the actual page, but for a page where the attacker wants you to be.

So an attacker is "piracy" a click that is not meant for the actual page, but for the page where the attacker wants you to be.

For example, using a carefully crafted combination of stylesheets, iframes, and text boxes, a user can be led to believe they are typing in the password for their bank account, but are actually typing into an invisible frame controlled by the attacker.

What is DNS Cache Poisoning?

DNS Cache Poisoning involves old cache data that you might think you no longer have on your computer, but is actually “toxic”.

DNS Cache poisoning involves old cache data that you might think is no longer on your computer, but is actually "toxic".

Also known as DNS spoofing, hackers can identify vulnerabilities in a domain name system, which allows them to convert traffic from legit servers to a fake website and/or server.

Also known as DNS Spoofing, hackers can identify vulnerabilities in the domain name system, allowing them to redirect traffic from legitimate servers to fake websites and/or servers.

This form of attack can spread and replicate itself from one DNS server to another DNS, “poisoning” everything in it’s path.

In fact, in 2010, a DNS poisoning attack completely compromised the Great Firewall of China (GFC) temporarily and censored certain content in the United States until the problem was fixed.
