Using software such as LOIC (Low Orbit Ion Cannon), many people can launch an attack against a website, server or router at the same time. This is a coordinated DDoS attack.
DoS and DDoS attacks are illegal under the law.
Basically, you just need a lot of computers. Not four of five, but more like a server farm. You will also need a program to drive each computer, telling it to download over and over. --Please don't try it.
HOIC (High Orbital Ion Cannon) can be used to launch both DoS and DDoS attacks. DoS and DDoS attacks are against the law, so I advise you that if you don't want to get arrested, you shouldn't execute one. Obviously you will be caught in the act if you do because you are a n00b.
The website owner would need to check the webserver log. DOS/DDOS attacks typically flood you with incoming data while legitimate users would be downloading items from your webserver.

What you are describing is not a type of malware, but a DoS (Denial of Service) attack.
DoS (Denial of Service) and DDoS (Distributed Denial of Service) attacks are very similar, but also different methods of attack. A DoS attack involves flooding a host with malformed or large TCP/IP packets in order to shut down the computer, website, or server. The large number of connection requests in a short amount of time renders the server basically useless as it tries to fulfill all of the requests, slowing it to a standstill. This standstill renders the server's resources unusable, hence the name Denial of Service, as computer users can no longer use the services provided. A DDoS attack is like a DoS attack but with one major difference: multiple computers launch a DoS attack against a target all at the same time. DDoS attacks are able to be done thanks to botnets, which is a network of computers that a hacker has compromised and connected them together in order to make a pool of available resources and vantage points. Once the hacker gives the signal, all of the computers in the botnet launch a DoS attack against a specified target.
HOIC (High Orbital Ion Cannon) can be used to launch both DoS and DDoS attacks. DoS and DDoS attacks are against the law, so I advise you that if you don't want to get arrested, you shouldn't execute one. Obviously you will be caught in the act if you do because you are a n00b.
There were many well coordinated attacks during World War II. However, the most coordinated attack was an attack called Wolfpack which encompassed the naval tactics.
A DDoS attack
A distributed denial-of-service (DDoS) attack is a malicious attempt to disrupt the normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic.
Distributed Denial of Service (DDoS) attack is another type of DoS attack. These attacks involve numerous systems coordinating a synchronised DoS attack on a single target. The key difference is that the target is attacked from numerous directions simultaneously rather than from a single entity. DDoS attackers frequently employ a , a collection of hijacked devices connected online, to launch large-scale attacks. Attackers use command and control software to exploit security flaws or hardware weaknesses to control many devices.
