For instance, they might want to bring down a site hosting a cybersecurity tool, or bring down a small online shop operating in the same niche. In other cases, malicious hackers use them as a form of extortion, where the victim has to pay a fee in order for the denial of service to stop.
Also, a DDoS attack can act as a smokescreen, hiding the real endgame, such as infecting the target with malware or extracting sensitive data.
And in what constitutes a frequent scenario, the attacker might not even have a motive. Some methods are easier to execute than others, but not as powerful. Other times, the attacker might want to go the extra mile, to really be sure the victim gets the message, so he can hire a dedicated botnet to carry out the attack..
A botnet is a collection of computers or other Internet-connected devices that have been infected with malware, and now respond to the orders and commands of a central computer, called the Command and Control center.
The big botnets have a web of millions of devices, and most of the owners have no clue their devices are compromised. Usually, botnets are used for a wide variety of illegal activities, such as pushing out spam emails, phishing or cryptocurrency mining. Some, however, are available to rent for the highest bidder, who can use them in whatever way seems fit. Oftentimes, this means a DDoS attack. This means using specialized tools, that can direct Internet traffic to a certain target.
Of course, the amount of traffic an individual computer can send is small, but crowdsource a few hundreds or thousands of users, and things suddenly grow in scope. This particular tactic has been successfully employed by Anonymous.
In short, they send a call to their followers, asking them to download a particular tool, and be active on messaging boards, such as IRC, at a particular time. They then simultaneously attack the target website or service, bringing it down. Because of its small scale and basic nature, ping of death attacks usually work best against smaller targets. For instance, the attacker can target:. However, in order for this to be successful, the malicious hacker must first find out the IP address of the device.
Flooding the router with data packets will prevent it from sending out Internet traffic to all other devices connected to it. In effect, this cuts the Internet access of any device that used the router. This is a relatively straightforward task , however. Using a script, he will create a neverending loop, where the Google Spreadsheet constantly asks the website to fetch the image. This huge amount of requests overwhelms the site and blocks it from sending outward traffic to visitors.
In most cases, the information transmitted between a client device and the server is too big to be sent in one piece. Because of this, the data is broken into smaller packets, and then reassembled again once it reaches the server.
Think of it as instructions to building a LEGO toy. What a teardrop attack does, is to send data packets at the server that make no sense, and have overlapping or dysfunctional offset parameters. The server tries, and fails, to order the data according to the malicious offset parameters.
This quickly consumes available resources until it grinds to a halt, taking down the website with it. To maximize every data byte, malicious hackers will sometimes amplify the flood by using a DNS reflection attack. What happens during amplification is that every 1 byte of information becomes 30 or 40 bytes, sometimes even more. Amplify this further using a botnet with a few thousand computers, and you can end up sending gygabytes of traffic towards a site.
Denial-of-Service attacks fall in two broad categories, depending on their main attack vector :. A network layer attack works by flooding the infrastructure used to host a website with vast amounts of data. If you do not have iTunes installed, try to access the iPod using Windows Explorer.
