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.
Linux malware includes viruses, Trojans, worms and other types of malware that affect the Linux family of operating systems. Linux, Unix and other Unix-like computer operating systems are generally regarded as very well-protected against, but not immune to, computer viruses.
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.
The Storm botnet or Storm worm botnet was a remotely controlled network of "zombie" computers that had been linked by the Storm Worm, a Trojan horse spread through e-mail spam. At its height in September 2007, the Storm botnet was running on anywhere from 1 million to 50 million computer systems, and accounted for 8% of all malware on Microsoft Windows computers. It was first identified around January 2007, having been distributed by email with subjects such as "230 dead as storm batters Europe," giving it its well-known name. The botnet began to decline in late 2007, and by mid-2008 had been reduced to infecting about 85,000 computers, far less than it had infected a year earlier.
A web threat is any threat that uses the World Wide Web to facilitate cybercrime. Web threats use multiple types of malware and fraud, all of which utilize HTTP or HTTPS protocols, but may also employ other protocols and components, such as links in email or IM, or malware attachments or on servers that access the Web. They benefit cybercriminals by stealing information for subsequent sale and help absorb infected PCs into botnets.
Koobface is a network worm that attacks Microsoft Windows, Mac OS X, and Linux platforms. This worm originally targeted users of networking websites like Facebook, Skype, Yahoo Messenger, and email websites such as GMail, Yahoo Mail, and AOL Mail. It also targets other networking websites, such as MySpace, Twitter, and it can infect other devices on the same local network. Technical support scammers also fraudulently claim to their intended victims that they have a Koobface infection on their computer by using fake popups and using built-in Windows programs.
The July 2009 cyberattacks were a series of coordinated cyberattacks against major government, news media, and financial websites in South Korea and the United States. The attacks involved the activation of a botnet—a large number of hijacked computers—that maliciously accessed targeted websites with the intention of causing their servers to overload due to the influx of traffic, known as a DDoS attack. Most of the hijacked computers were located in South Korea. The estimated number of the hijacked computers varies widely; around 20,000 according to the South Korean National Intelligence Service, around 50,000 according to Symantec's Security Technology Response group, and more than 166,000 according to a Vietnamese computer security researcher who analyzed the log files of the two servers the attackers controlled. An investigation revealed that at least 39 websites were targets in the attacks based on files stored on compromised systems.
Waledac, also known by its aliases Waled and Waledpak, was a botnet mostly involved in e-mail spam and malware. In March 2010 the botnet was taken down by Microsoft.
Sality is the classification for a family of malicious software (malware), which infects files on Microsoft Windows systems. Sality was first discovered in 2003 and has advanced over the years to become a dynamic, enduring and full-featured form of malicious code. Systems infected with Sality may communicate over a peer-to-peer (P2P) network to form a botnet for the purpose of relaying spam, proxying of communications, exfiltrating sensitive data, compromising web servers and/or coordinating distributed computing tasks for the purpose of processing intensive tasks. Since 2010, certain variants of Sality have also incorporated the use of rootkit functions as part of an ongoing evolution of the malware family. Because of its continued development and capabilities, Sality is considered to be one of the most complex and formidable forms of malware to date.
United States of America v. Ancheta is the name of a lawsuit against Jeanson James Ancheta of Downey, California by the U.S. Government and was handled by the United States District Court for the Central District of California. This is the first botnet related prosecution in U.S history.
The Kelihos botnet, also known as Hlux, is a botnet mainly involved in spamming and the theft of bitcoins.
The Microsoft Digital Crimes Unit (DCU) is a Microsoft sponsored team of international legal and internet security experts employing the latest tools and technologies to stop or interfere with cyber crime and cyber threats. The Microsoft Digital Crimes Unit was assembled in 2008. In 2013, a Cybercrime center for the DCU was opened in Redmond, Washington. There are about 100 members of the DCU stationed just in Redmond, Washington at the original Cybercrime Center. Members of the DCU include lawyers, data scientists, investigators, forensic analysts, and engineers. The DCU has international offices located in major cities such as: Beijing, Berlin, Bogota, Delhi, Dublin, Hong Kong, Sydney, and Washington, D.C. The DCU's main focuses are child protection, copyright infringement and malware crimes. The DCU must work closely with law enforcement to ensure the perpetrators are punished to the full extent of the law. The DCU has taken down many major botnets such as the Citadel, Rustock, and Zeus. Around the world malware has cost users about $113 billion and the DCU's jobs is to shut them down in accordance with the law.
Operation Tovar is an international collaborative operation carried out by law enforcement agencies from multiple countries against the Gameover ZeuS botnet, which is believed by the investigators to have been used in bank fraud and the distribution of the CryptoLocker ransomware.
GameOverZeus is a peer-to-peer botnet based on components from the earlier ZeuS trojan. The malware was created by Russian hacker Evgeniy Mikhailovich Bogachev. It is believed to have been spread through use of the Cutwail botnet.
Lazarus Group is a cybercrime group made up of an unknown number of individuals run by the North Korean state. While not much is known about the Lazarus Group, researchers have attributed many cyberattacks to them between 2010 and 2021. Originally a criminal group, the group has now been designated as an advanced persistent threat due to intended nature, threat, and wide array of methods used when conducting an operation. Names given by cybersecurity organizations include HIDDEN COBRA and Zinc.
Dridex also known as Bugat and Cridex is a form of malware that specializes in stealing bank credentials via a system that utilizes macros from Microsoft Word.
Mirai is a malware that turns networked devices running Linux into remotely controlled bots that can be used as part of a botnet in large-scale network attacks. It primarily targets online consumer devices such as IP cameras and home routers. The Mirai botnet was first found in August 2016 by MalwareMustDie, a white hat malware research group, and has been used in some of the largest and most disruptive distributed denial of service (DDoS) attacks, including an attack on 20 September 2016 on computer security journalist Brian Krebs' web site, an attack on French web host OVH, and the October 2016 Dyn cyberattack. According to a chat log between Anna-senpai and Robert Coelho, Mirai was named after the 2011 TV anime series Mirai Nikki.
