Linux.Wifatch
Linux.Wifatch is an open-source piece of malware which has been noted for not having been used for malicious actions, instead attempting to secure devices from other malware. Linux.Wifatch operates in a manner similar to a computer security system and updates definitions through its Peer to Peer network and deletes remnants of malware which remain. Linux.Wifatch has been active since at least November 2014. According to its authors the idea for Linux.Wifatch came after reading the Carna paper. Linux.Wifatch was later released on GitLab by its authors under the GNU General Public License on October 5, 2015. Operation Linux.Wifatch's primary mode of infection is by logging into devices using weak or default telnet credentials. Once infected, Linux.Wifatch removes other malware and disables telnet access, replacing it with the message "Telnet has been closed to avoid further infection of his device. Please disable telnet, change telnet passwords, and/or update the firmware." S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hajime (malware)
Hajime (Japanese for "beginning") is a malware which appears to be similar to the Wifatch malware in that it appears to attempt to secure devices. Hajime is also far more advanced than Mirai, according to various researchers. The top countries infected by the malware were Iran, Brazil, Vietnam, Russia and Turkey, followed by India, Pakistan, Italy and Taiwan. Malware Hajime is a worm according to sources which have placed research on the subject. It appears to have been discovered as early as October 2016. Later in April 2017, Hajime generated large media coverage as it appeared to be in competition with Mirai. This led to a number of reports which compared and noted that it appeared to have a similar purpose to Linux.Wifatch. It also did not contain any modules or tools for denial of service attacks, but instead only contained methods for extending its reach. Hand written assembly code specifically for several platforms was also discovered by researchers as well. Hajime is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carna Botnet
The Carna botnet was a botnet of 420,000 devices created by an anonymous hacker to measure the extent of the Internet in what the creator called the “Internet Census of 2012”. Data collection The data was collected by infiltrating Internet devices, especially routers, that used a default password or no password at all. It was named after Carna, "the Roman goddess for the protection of inner organs and health".Internet Census 2012: Port scanning /0 using insecure embedded devices , Carna Botnet, June - Oktober 2012 Collected data was compiled into a portrait to display Internet use around the world over the course of 24 hours. The data gathered included only the [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mirai (malware)
Mirai (from the Japanese word for "future", 未来) 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' website, 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''. The software was initially used by the creators to DDoS ''Minecraft'' servers and companies offering DDoS protection to ''Minecraft'' servers, with the authors using Mirai to operate a protection r ...

Remaiten
Remaiten is malware which infects Linux Linux on embedded systems, on embedded systems by Brute-force attack, brute forcing using frequently used default username and Default password, passwords combinations from a list in order to infect a system. Remaiten combines the features of the Tsunami and BASHLITE, LizardStresser (aka Torlus) malware families. The command and control for Remaiten are handled by IRC communications. Additionally the command and control is done by an actual IRC channel rather than only the IRC protocol. This is an improvement over bots such as Tsunami and BASHLITE, Torlus making Remaiten a greater threat than both combined. To avoid detection, Remaiten tries to determine the platform of a device to download the architecture-appropriate component from the command & control server. Once Remaiten infects a device it is able to perform actions such as launching distributed denial of service attacks or download more malware on a device. Remaiten is able to scan ...

Malware
Malware (a portmanteau for ''malicious software'') is any software intentionally designed to cause disruption to a computer, server, client, or computer network, leak private information, gain unauthorized access to information or systems, deprive access to information, or which unknowingly interferes with the user's computer security and privacy. By contrast, software that causes harm due to some deficiency is typically described as a software bug. Malware poses serious problems to individuals and businesses on the Internet. According to Symantec's 2018 Internet Security Threat Report (ISTR), malware variants number has increased to 669,947,865 in 2017, which is twice as many malware variants as in 2016. Cybercrime, which includes malware attacks as well as other crimes committed by computer, was predicted to cost the world economy $6 trillion USD in 2021, and is increasing at a rate of 15% per year. Many types of malware exist, including computer viruses, worms, Trojan horses, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BASHLITE
BASHLITE (also known as Gafgyt, Lizkebab, PinkSlip, Qbot, Torlus and LizardStresser) 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 original version in 2014 exploited a flaw in the bash shell - the Shellshock software bug - to exploit devices running BusyBox. A few months later a variant was detected that could also infect other vulnerable devices in the local network. In 2015 its source code was leaked, causing a proliferation of different variants, and by 2016 it was reported that one million devices have been infected. Of the identifiable devices participating in these botnets in August 2016 almost 96 percent were IoT devices (of which 95 percent were cameras and DVRs), roughly 4 percent were home routers - and less than 1 percent were ...

IoT Malware
The Internet of things (IoT) describes physical objects (or groups of such objects) with sensors, processing ability, software and other technologies that connect and exchange data with other devices and systems over the Internet or other communications networks. Internet of things has been considered a misnomer because devices do not need to be connected to the public internet, they only need to be connected to a network and be individually addressable. The field has evolved due to the convergence of multiple technologies, including ubiquitous computing, commodity sensors, increasingly powerful embedded systems, as well as machine learning.Hu, J.; Niu, H.; Carrasco, J.; Lennox, B.; Arvin, F.,Fault-tolerant cooperative navigation of networked UAV swarms for forest fire monitoring Aerospace Science and Technology, 2022.

Botnets
A botnet is a group of Internet-connected devices, each of which runs one or more Internet bot, bots. Botnets can be used to perform distributed denial-of-service attack, Distributed Denial-of-Service (DDoS) attacks, steal data, send Spamming, 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 "Computer network, network". The term is usually used with a negative or malicious connotation. Overview A botnet is a logical collection of Internet-connected devices, such as computers, smartphones or Internet of things (IoT) devices whose Computer security, security have been breached and control ceded to a third party. Each compromised device, known as a "bot," is created when a device is penetrated by software from a ''malware'' (malicious software) distribution. The controller of a botnet is able to direct the activities of these com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telnet
Telnet is an application protocol used on the Internet or local area network to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. User data is interspersed in-band with Telnet control information in an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP). Telnet was developed in 1969 beginning with , extended in , and standardized as Internet Engineering Task Force (IETF) Internet Standard STD 8, one of the first Internet standards. The name stands for " teletype network". Historically, Telnet provided access to a command-line interface on a remote host. However, because of serious security concerns when using Telnet over an open network such as the Internet, its use for this purpose has waned significantly in favor of SSH. The term ''telnet'' is also used to refer to the software that implements the client part of the protocol. Telnet client applications are available for virtually all c ...

Denial-of-service Attack
In computing, a denial-of-service attack (DoS 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. In a distributed denial-of-service attack (DDoS attack), the incoming traffic flooding the victim originates from many different sources. More sophisticated strategies are required to mitigate this type of attack, as simply attempting to block a single source is insufficient because there are multiple sources. A DoS or DDoS attack is analogous to a group of people crowding the entry door of a shop, making it hard for legitimate customers to enter, thus disrupting trade. Criminal perpetrators of DoS attacks oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
