Low Orbit Ion Cannon (LOIC) is an open-source network stress testing and denial-of-service attack application written in C#. LOIC was initially developed by Praetox Technologies, however it was later released into the public domain [2] and is currently available on several open-source platforms. [3] [4]
LOIC performs a DoS attack (or, when used by multiple individuals, a DDoS attack) on a target site by flooding the server with TCP, UDP, or HTTP packets with the intention of disrupting the service of a particular host. People have used LOIC to join voluntary botnets. [5]
The software inspired the creation of an independent JavaScript version called JS LOIC, as well as LOIC-derived web version called Low Orbit Web Cannon. These enable a DoS from a web browser. [6] [7] [8]
Security experts quoted by the BBC indicated that well-written firewall rules can filter out most traffic from DDoS attacks by LOIC, thus preventing the attacks from being fully effective. [9] In at least one instance, filtering out all UDP and ICMP traffic blocked a LOIC attack. [10] Firewall rules of this sort are more likely to be effective when implemented at a point upstream of an application server's Internet uplink to avoid the uplink from exceeding its capacity. [10]
LOIC attacks are easily identified in system logs, and the attack can be tracked down to the IP addresses used. [11]
LOIC was used by Anonymous (a group that spawned from the /b/ board of 4chan) during Project Chanology to attack websites from the Church of Scientology, once more to (successfully) attack the Recording Industry Association of America's website in October 2010, [12] and it was again used by Anonymous during their Operation Payback in December 2010 to attack the websites of companies and organizations that opposed WikiLeaks. [13] [14]
In retaliation for the shutdown of the file sharing service Megaupload and the arrest of four workers, members of Anonymous launched a DDoS attack upon the websites of Universal Music Group (the company responsible for the lawsuit against Megaupload), the United States Department of Justice, the United States Copyright Office, the Federal Bureau of Investigation, the MPAA, Warner Music Group and the RIAA, as well as the HADOPI, all on the afternoon of January 19, 2012, through LOIC. [15] In general, the attack hoped to retaliate against those who Anonymous members believed harmed their digital freedoms. [16]
The LOIC application is named after the ion cannon, a fictional weapon from many sci-fi works, video games, [17] and in particular after its namesake from the Command & Conquer series. [18] The artwork used in the application was a concept art for Command & Conquer 3: Tiberium Wars .
DALnet is an Internet Relay Chat (IRC) network made up of 39 servers, with a stable population of approximately 10,000 users in about 4,000 channels.
In computing, a denial-of-service attack is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. The range of attacks varies widely, spanning from inundating a server with millions of requests to slow its performance, overwhelming a server with a substantial amount of invalid data, to submitting requests with an illegitimate IP address.
A botnet is a group of Internet-connected devices, each of which runs one or more bots. Botnets can be used to perform distributed denial-of-service (DDoS) attacks, steal data, send spam, and allow the attacker to access the device and its connection. The owner can control the botnet using command and control (C&C) software. The word "botnet" is a portmanteau of the words "robot" and "network". The term is usually used with a negative or malicious connotation.
A UDP flood attack is a volumetric denial-of-service (DoS) attack using the User Datagram Protocol (UDP), a sessionless/connectionless computer networking protocol.
Stacheldraht is malware which performs a distributed denial-of-service (DDoS) attack. It was written by "Thomas Stacheldraht", a member of the Austrian hacker group TESO. It was first released in 1999.
Megaupload Ltd was a Hong Kong–based online company established in 2005 that operated from 2005 to 2012 providing online services related to file storage and viewing.
The Tribe Flood Network or TFN is a set of computer programs to conduct various DDoS attacks such as ICMP flood, SYN flood, UDP flood and Smurf attack.
The trinoo or trin00 is a set of computer programs to conduct a DDoS attack. It is believed that trinoo networks have been set up on thousands of systems on the Internet that have been compromised by remote buffer overrun exploits.
Anonymous is a decentralized international activist and hacktivist collective and movement primarily known for its various cyberattacks against several governments, government institutions and government agencies, corporations and the Church of Scientology.
Slowloris is a type of denial of service attack tool which allows a single machine to take down another machine's web server with minimal bandwidth and side effects on unrelated services and ports.
w3af is an open-source web application security scanner. The project provides a vulnerability scanner and exploitation tool for Web applications. It provides information about security vulnerabilities for use in penetration testing engagements. The scanner offers a graphical user interface and a command-line interface.
Operation Payback was a coordinated, decentralized group of attacks on high-profile opponents of Internet piracy by Internet activists using the "Anonymous" moniker. Operation Payback started as retaliation to distributed denial of service (DDoS) attacks on torrent sites; piracy proponents then decided to launch DDoS attacks on piracy opponents. The initial reaction snowballed into a wave of attacks on major pro-copyright and anti-piracy organizations, law firms, and individuals. The Motion Picture Association of America, the Pirate Party UK and United States Pirate Party criticised the attacks.
Anonymous is a decentralised virtual community. They are commonly referred to as an internet-based collective of hacktivists whose goals, like its organization, are decentralized. Anonymous seeks mass awareness and revolution against what the organization perceives as corrupt entities, while attempting to maintain anonymity. Anonymous has had a hacktivist impact. This is a timeline of activities reported to be carried out by the group.
Multiple criminal indictments and enforcement actions were taken against Megaupload owner Kim Dotcom in various jurisdictions. On 19 January 2012 the United States Department of Justice seized and shut down the file-hosting site Megaupload.com and commenced criminal cases against its owners and others. On 20 January 2012 Hong Kong Customs froze more than 300 million Hong Kong dollars in assets belonging to the company.
SlowDroid is the first denial of service attack which allows a single mobile device to take down a network server requiring minimal bandwidth. The attack has been created for research purposes by Enrico Cambiaso and Maurizio Aiello for the IEIIT Institute of the National Research Council of Italy and released as an Android application.
High Orbit Ion Cannon (HOIC) is an open-source network stress testing and denial-of-service attack application designed to attack as many as 256 URLs at the same time. It was designed to replace the Low Orbit Ion Cannon which was developed by Praetox Technologies and later released into the public domain. The security advisory for HOIC was released by Prolexic Technologies in February 2012.
Zemra is a DDoS Bot which was first discovered in underground forums in May 2012.
BASHLITE is malware which infects Linux systems in order to launch distributed denial-of-service attacks (DDoS). Originally it was also known under the name Bashdoor, but this term now refers to the exploit method used by the malware. It has been used to launch attacks of up to 400 Gbps.
The BlackNurse attack is a form of denial of service attack based on ICMP flooding. The attack is special because a modest bandwidth of 20 Mbit/s can be effective for disrupting a victim's network.
On September 3, 2020, at 2:53 am EDT, a 16-year-old male from South Miami, Florida was arrested in connection with distributed denial-of-service (DDoS) attacks on the Miami-Dade County Public Schools's computer network, the fourth largest in the US, causing the system to crash during the first three days of the school year. It occurred as the school system was attempting to conduct internet-based instruction during the COVID-19 pandemic of 2020. After monitoring the IP addresses using the network, investigators concluded the teenager and several foreign actors had hacked the system. At the time, the school district had contracted Stride, Inc. to provide the software necessary for the internet-based instruction. Despite its price tag of $15.3 million, Stride was surprisingly susceptible to the attacks. Consequently, the school district sought the help of the FBI and U.S. Secret Service to investigate.
