People have used LOIC to join.The software inspired the creation of an independent version called JS LOIC, as well as LOIC-derived web version called Low Orbit Web Cannon. These enable a DoS from a.

CountermeasuresSecurity experts quoted by the BBC indicated that well-written rules can filter out most traffic from DDoS attacks by LOIC, thus preventing the attacks from being fully effective. In at least one instance, filtering out all and traffic blocked a LOIC attack. Because internet service providers provide less bandwidth to each of their customers in order to provide guaranteed service levels for all of their customers at once, firewall rules of this sort are more likely to be effective when implemented at a point upstream of an application server's internet uplink. In other words, it is easy to cause an ISP to drop traffic destined for a customer by sending a greater amount of traffic than is allowed on that customer's link, and any filtration that occurs on the customer side after the traffic traverses that link will not stop the service provider from dropping excess traffic destined for that customer.LOIC attacks are easily identified in system logs, and the attack can be tracked down to the IP addresses used.

In general, the attack hoped to retaliate against those who Anonymous members believed harmed their digital freedoms. Origin of nameThe LOIC application is named after the, a fictional weapon from many sci-fi works, video games, and in particular after its namesake from the series. LegalityWhile downloading and using the LOIC on one's own personal servers as a means of stress-testing is perfectly legal at least in the United States, using the program to perform a DDoS attack on other parties could be considered a felony under the Computer Fraud and Abuse Act of 1986. (CFAA) This charge could result in up to 20 years of imprisonment, a fine or both.

In computing, a zombie is a computer connected to the Internet that has been compromised by a hacker, computer virus or trojan horse program and can be used to perform malicious tasks of one sort or another under remote direction. Botnets of zombie computers are often used to spread e-mail spam and launch denial-of-service attacks. Most owners of 'zombie' computers are unaware that their system is being used in this way. Because the owner tends to be unaware, these computers are metaphorically compared to fictional zombies. A coordinated DDoS attack by multiple botnet machines also resembles a 'zombie horde attack', as depicted in fictional zombie films.

An XML denial-of-service attack is a content-borne denial-of-service attack whose purpose is to shut down a web service or system running that service. A common XDoS attack occurs when an XML message is sent with a multitude of digital signatures and a naive parser would look at each signature and use all the CPU cycles, eating up all resources. These are less common than inadvertent XDoS attacks which occur when a programming error by a trusted customer causes a handshake to go into an infinite loop.
