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 ...

Linux Malware
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. Linux vulnerability Like Unix systems, Linux implements a multi-user environment where users are granted specific privileges and there is some form of access control implemented. To gain control over a Linux system or to cause any serious consequences to the system itself, the malware would have to gain root access to the system. In the past, it has been suggested that Linux had so little malware because its low market share made it a less profitable target. Rick Moen, an experienced Linux system administrator, counters that: In 2008 the quantity of malware targeting Linux was noted as increasing. Shane Coursen, a senior technical consultant with Kaspersky Lab, said at the time, "The growth in Linux malwa ... [...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 ...

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] |
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] |
Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

Linux On Embedded Systems
Operating systems based on the Linux kernel are used in embedded systems such as consumer electronics (eg. set-top boxes, smart TVs and personal video recorders (PVRs)), in-vehicle infotainment (IVI), networking equipment (such as routers, switches, wireless access points (WAPs) or wireless routers), machine control, industrial automation, navigation equipment, spacecraft flight software, and medical instruments in general. Because of their versatility, operating systems based on the Linux kernel can be also found in mobile devices that are actually touchscreen-based embedded devices, such as smartphones and tablets, together with personal digital assistants (PDAs) and portable media players that also include a touchscreen. This is a challenge for most learners because their computer experience is mainly based on GUI (Graphical user interface) based interaction with the machine and high-level programming on the one hand and low-level programming of small microcontrollers (MCU) ...

Brute-force Attack
In cryptography, a brute-force attack consists of an attacker submitting many passwords or passphrases with the hope of eventually guessing correctly. The attacker systematically checks all possible passwords and passphrases until the correct one is found. Alternatively, the attacker can attempt to guess the key which is typically created from the password using a key derivation function. This is known as an exhaustive key search. A brute-force attack is a cryptanalytic attack that can, in theory, be used to attempt to decrypt any encrypted data (except for data encrypted in an information-theoretically secure manner). Such an attack might be used when it is not possible to take advantage of other weaknesses in an encryption system (if any exist) that would make the task easier. When password-guessing, this method is very fast when used to check all short passwords, but for longer passwords other methods such as the dictionary attack are used because a brute-force search ta ...

Default Password
Where a device needs a username and/or password to log in, a default password is usually provided that allows the device to be accessed during its initial setup, or after resetting to factory defaults. Manufacturers of such equipment typically use a simple password, such as ''admin'' or ''password'' on all equipment they ship, in the expectation that users will change the password during configuration. The default username and password is usually found in the instruction manual (common for all devices) or on the device itself. Default passwords are one of the major contributing factors to large-scale compromises of home routers. Leaving such a password on devices available to the public is a huge security risk. Some devices (such as wireless routers) will come with uniqudefault router username and passwordsprinted on a sticker, which is a more secure option than a common default password. Some vendors will however derive the password from the device's MAC address using a know ... [...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 ...

Botnet
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. Overview A botnet is a logical collection of Internet-connected devices, such as computers, smartphones or Internet of things (IoT) devices whose 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 compromised computers through communication channels formed by standards-based network protocols, su ...

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.
