My suggestion to you is to look at “Man-in-the-browser”. Zombie means that a computer connected to the Internet has been compromised by a hacker. In DDoS, an attacker can use The Zombie technique to capture many computers and send many requests to the victim via them or bots.

Block destinations and authorized users can’t gain access to it.

Sending many packets to targets to flood them and finally crash and shut down.

Send invalid data to applications or network services.

Disruption of physical network components, like routers and switches and firewalls.

Destroy routing information and routing tables.

You’re right, some malware is a kind of Dos attack. As I guess, your mind might digress to malware.

Use of computational resources, like bandwidth, memory, disk space or even CPU.

This attack targets gateways and web servers, like banks, and doing some of the below sabotages: The goal is interrupted or suspended services that connect to the Internet.

Please look at the below picture.ĭenial-of-service attack (Dos): In this kind of attack, an attacker attempts to make a machine or network resource unavailable for users. It may seem old, but you can be sure it is one of the biggest security problems in a network that network administrators disregard. When you chat with your friend in “clear text” mode, sniffing your traffic is possible. This kind of attack happens in computer communications, too, but it’s known as sniffing. A very simple way is to secretly listen to their words. Imagine that you want to find some information about two friends and their relationship. I will show you some texts about the above options and introduce other attacks to you.Įavesdropping: I’m sure you are familiar with it it’s very normal in life. I want to familiarize you with different types of active and passive attacks: This attack is more like monitoring and recognition of the target.

Passive attack: In this kind of attack, The Attacker attempts to gain information from the system without destroying the information.

Active attack: In this kind of attack, The Attacker attempts to alter system resources or destroy the data.

Attacks are not always simple most of them are complex and it is a big challenge for security researchers and companies that offer a solution for them. An attacker is a person that steals your data without permission and a feature of some attacks is that they are hidden. In the computer world, an attack is a way to destroy, expose and gain unauthorized access to data and computers. Please correct your blog entry in order to not spread false information.Ettercap and man in middle-attacks tutorial ettercap Either the Domain is there but doesn't have records for this record type or it is not there. This leads to the result that the DNS resolver gets NXDOMAIN responses and A responses which seem to confuse a number of DNS resolvers. So while you're only spoofing responses to type A queries, the DNS resolver will in parallel fire AAAA queries, your example of etter.dns ignores. The second issue your blog entry introduces, is the fact that it ignores the fact of a world with IPv6 in parallel to IPv4. It even lead to unwanted issues when not handled carefully, since then, Ettercap tries to intercept the SSL handshake of every SSL enabled protocol by default with it's self-signed certificate. The first main issue is that uncommenting the redir_command_on, redir_command_off commands are NOT necessary to run this attack.

It appears that this blog is providing unprecise information of how to use Ettercap to run a DNS spoof attack. I've been noticed about this blog by one of the Ettercap users. Open our terminal window and edit nf file in any text editor.

How to install ettercap on kali linux? You don't need Ettercap comes pre-installed with Kali Linux, before open it we do some configuration. Ettercap is a very popular and easy DNS spoofing tool. Here for this tutorial we use Ettercap to spoof DNS. With the help of DNS spoofing attacker can inject poison in victim's address resolution protocol, and this attack is very hard to detect.

This results in traffic being diverted to the attacker's computer or any other system.

In this method attacker can divert a domain name to a incorrect IP. This means if it receives another request for same translation, it can replay without needing to ask any other servers until the cache expires.ĭNS spoofing is a crucial part of penetration testing. To reduce the effort and improve the performance DNS saves translate data for a limited time which called cache. So a domain name attached with the IP address. As we know every system have an unique IP address, but it is very difficult to remember IP address of many website for a human.
