And these types of attacks can be applied to any version of Windows, of course this will also depend on the strength of the attack may if you need a botnet (network of computers controlled by you) in algunsh cases.
Now imdependente the type of attack we used to call most of these types of attacks such as DoS (Denial of Service). The DoS attack is one that is based on the denial of service. A network-connected web, or internal network (in the case of saboteurs) with a very good connection sends a large number of packages, as more and more fragmented packets, logically there better then a target machine that you can not interpret the large number of packets received will be the cause of denial of service, knocking the services hosted on it, and it is very important to note the words "many" and "fragmented packets." Such attacks, launched by long periods of time and systematically sçao able even to overturn well-configured firewalls that simply fulfill their function - to deny unauthorized connections - until the system goes haywire. Let's start the article now.
UDP flood
A flood attack (UDP flood) is a denial of service (or DoS) using the UDP protocol for causing loss of connection from the computer. Remember when your server or workstation exits the network '. It can be a UDP flood.
UDP (User Datagram Protocol) are not connection oriented, ie, there is a relationship between durable packets sent to port to a remote machine. The UDP must know that there is only one port, interface and host (machine) to receive the packet sent its source interface, and it only ever satisfies. Why UDP is not a secure protocol and if you want to take care of the security of your network add rules to your firewall strict regarding this protocol, or disable. Interfaces that receive UDP packets do not need to create a lasting relationship with the issuer, following this policy. Indeed, they may also receive connections from more than one source UDP packet using the same socket receiving packets addressed and new indefinitely. A full plate for a hacker attack.
Such an attack is usually initiated by sending a large number of UDP packets to random ports on a remote machine. A simple implementation manual and this technique can be performed with the help of hping, a powerful command line tool that far surpasses the capabilities of traditional ping Windows (and Linux too). The hping can be obtained from your Linux version at the address http://www.hping.org to tweak the Windows version does not cost the site or on Google right? But it will take to build. There is also a suite of programs called Net Tools, Network Tools menu there you will have the UDP flooder can be downloaded on the official website in http://mabsoft.com (Date, already in the UDP flooder Net Tools, use the data format 3DLVI%% 26its% 3Di% 3D1% 26otn, it will provide a reasonably powerful attack).
HTTP or SYN flood
Clearly the previous attack (UDP flood) would take only cause nuisance or air occasionally, but is not able to take a robust server or an entire website from the air. But can an HTTP flood.
An HTTP flood is nothing more than a SYN flood with right destination to port 80 (Internet port) of a machine, server or router. The SYN packets are sync, responsible for taking the first step to start any connection on a TCP / IP network.
In this mode, a client requests a connection by sending a SYN (SYNC) to the server. The server, in turn, confirms this request by sending a SYN-ACK (acknowledge) back to the client. The client, in turn, ending process that is often called the Three-Way Handshake (Handshake in three stages), warns that the connection is finally established, by means of an ACK.
A SYN attack or HTTP flood occurs in a very simple way: the ACK is never sent, which causes the server to wait for him. At the same time, tens or hundreds of requests are sent in the same manner and with the same defect. It was an attack similar to that which toppled the Twitter service on August 6, 2009. The Net Tools I mentioned earlier has a tool for HTTP Flood, but that does not work. Therefore, you may choose to use a tool known as Port Scanner systems and pen test, but which is able to generate DoS attacks better than many hacker tools, though this is not your (or our) intention . We're talking about Shadow Security Scanner tool coaster that can be purchased at: http://www.safety-lab.com/SSS.exe. This copy of the program can be used for 15 days but if you continuously working pen tests and networks, it's worth buying it.
After installing the software, start it and it will update, configure a proxy after it is fully charged to use and hide your IP, leave HTTP Proxy, please http://www.samair.ru/proxy/ proxy-01.htm, a list of famous and anonymous proxies free. Choose the connection port matching and fill in the rest, if any proxy does not work, try another. Now open the program interface, click the icon DoS Checker, then click the option HTTP Stress. Fill the Host with the target IP if your network try the tracert command in ms-dos. Now adjust the threads, Delay and Packet size to the maximum size (a quick way to launch the attack), click Start and watch the action.
Arp flood
The ARP (Address Resolution Protocol) was developed to solve the problem of mapping logical addresses into physical addresses in Ethernet networks based on IP, but not restricted to only these two protocols (the case of TCP / IP networks). The problem is that the ARP protocol operates in broadcasting, ie broadcasts to all stations in the network to find the address to which it is intended. Furthermore has an infrastructure easily manipulated, making its use for very simple attacks.
Let's see now the attack using WinArpAttacker, a tool perfectly legal (poe be used for safety testing), which can also be used for destructive purposes or demonic, since it is able to find IP assets on the network, identify open ports on machines and direct an attack to target exactly ARP escolido. The software can be downloaded at: http://xfocus.net/tools/.
One. By downloading the software you may need to install Winpcap which should accompany the download package rar;
2nd. Open the program and locate the arrow next to the Scan button, click it, and select Scan Lan (Of course, this form will only show the machines only entitled to receive packages promiscuous mode, or listen to the broadcastings of the network for better configuration click the arrow next to the Scan button and click Advanced;
3rd. Scan window appears, select Scan the local networks, select the networks present there;
4th. Click Antsniff;
5th. Press Scan ARP cache and the network will be revealed in minutes;
6th. Select the target, click on the arrow next to the button and click ARP Flood Attack (equivalent to a thousand ARP packets with random addresses);
7th. To perform stronger attacks click the Options button, then click on the tab Attack on line ARP Flood teams (1-10,000,000) enter the value: 10 million (10 million);
And there may be more options of attacks and strategies to be taken to the settings of the software attack, but we will not deepen if it is not too easy, try to find out, make sense "test" worthwhile and that's how you learn.
