Subseven
Sub7, or SubSeven or Sub7Server, is a Trojan horse program originally released in 1999. Its name was derived by spelling NetBus backwards ("suBteN") and swapping "ten" with "seven". As of June 2021, the development of Sub7 is being continued. Because its typical use is to allow undetected and unauthorized access, Sub7 is usually described as a trojan horse by security experts. Starting with version 2.1 (1999) it could be controlled via IRC. As one security book phrased it: "This set the stage for all malicious botnets to come." Additionally Sub7 has some features deemed of little use in legitimate remote administration like keystroke logging. Sub7 worked on the Windows 9x and on the Windows NT family of operating systems, up to and including Windows 8.1. History Sub7 has been claimed to be the creation of a hacker with the handle "mobman". Some sources claim that the software has been developed by an unknown Romanian programmer. Until today, "mobman" claims to be the crea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Penetration Test
A penetration test, colloquially known as a pen test or ethical hacking, is an authorized simulated cyberattack on a computer system, performed to evaluate the security of the system; this is not to be confused with a vulnerability assessment. The test is performed to identify weaknesses (also referred to as vulnerabilities), including the potential for unauthorized parties to gain access to the system's features and data, as well as strengths, enabling a full risk assessment to be completed. The process typically identifies the target systems and a particular goal, then reviews available information and undertakes various means to attain that goal. A penetration test target may be a white box (about which background and system information are provided in advance to the tester) or a black box (about which only basic information—if any—other than the company name is provided). A gray box penetration test is a combination of the two (where limited knowledge of the target is sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MiniPanzer And MegaPanzer
MiniPanzer and MegaPanzer are two variants of ''Bundestrojaner'' (German for federal Trojan horse) written for ERA IT Solutions (a Swiss federal government contractor) by software engineer Ruben Unteregger, and later used by Switzerland's Federal Department of Environment, Transport, Energy and Communications (UVEK) to intercept Skype and more generally voice over IP traffic on Windows XP systems. The source code of the program was released under the GNU General Public License version 3 (GPLv3) in 2009 by their author, who retained the copyright. Thereafter, the trojan was apparently detected in the wild. One of its designations given by anti-virus companies was ''Trojan.Peskyspy''. The malware used DLL injection In computer programming, DLL injection is a technique used for running code within the address space of another process by forcing it to load a dynamic-link library.

Rootkit
A rootkit is a collection of computer software, typically malicious, designed to enable access to a computer or an area of its software that is not otherwise allowed (for example, to an unauthorized user) and often masks its existence or the existence of other software. The term ''rootkit'' is a compound of "root" (the traditional name of the privileged account on Unix-like operating systems) and the word "kit" (which refers to the software components that implement the tool). The term "rootkit" has negative connotations through its association with malware. Rootkit installation can be automated, or an attacker can install it after having obtained root or administrator access. Obtaining this access is a result of direct attack on a system, i.e. exploiting a vulnerability (such as privilege escalation) or a password (obtained by cracking or social engineering tactics like "phishing"). Once installed, it becomes possible to hide the intrusion as well as to maintain privileged acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backdoor (computing)
A backdoor is a typically covert method of bypassing normal authentication or encryption in a computer, product, embedded device (e.g. a home router), or its embodiment (e.g. part of a cryptosystem, algorithm, chipset, or even a "homunculus computer" —a tiny computer-within-a-computer such as that found in Intel's Intel Active Management Technology, AMT technology). Backdoors are most often used for securing remote access to a computer, or obtaining access to plaintext in cryptographic systems. From there it may be used to gain access to privileged information like passwords, corrupt or delete data on hard drives, or transfer information within autoschediastic networks. A backdoor may take the form of a hidden part of a program, a separate program (e.g. Back Orifice may subvert the system through a rootkit), code in the hardware backdoor, firmware of the hardware, or parts of an operating system such as Microsoft Windows, Windows. Trojan horse (computing), Trojan horses can be u ... [...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] |
Back Orifice
Back Orifice (often shortened to BO) is a computer program designed for remote system administration. It enables a user to control a computer running the Microsoft Windows operating system from a remote location.Richtel, Matt.Hacker Group Says Program Can Exploit Microsoft Security Hole" ''The New York Times'' August 4, 1998. Retrieved April 24, 2007. The name is a play on words on Microsoft BackOffice Server software. It can also control multiple computers at the same time using imaging. Back Orifice has a client–server architecture. A small and unobtrusive server program is on one machine, which is remotely manipulated by a client program with a graphical user interface on another computer system. The two components communicate with one another using the TCP and/or UDP network protocols. In reference to the Leet phenomenon, this program commonly runs on port 31337. The program debuted at DEF CON 6 on August 1, 1998 and was the brainchild of Sir Dystic, a member of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Worm
A computer worm is a standalone malware computer program that replicates itself in order to spread to other computers. It often uses a computer network to spread itself, relying on security failures on the target computer to access it. It will use this machine as a host to scan and infect other computers. When these new worm-invaded computers are controlled, the worm will continue to scan and infect other computers using these computers as hosts, and this behaviour will continue. Computer worms use recursive methods to copy themselves without host programs and distribute themselves based on the law of exponential growth, thus controlling and infecting more and more computers in a short time. Worms almost always cause at least some harm to the network, even if only by consuming bandwidth, whereas viruses almost always corrupt or modify files on a targeted computer. Many worms are designed only to spread, and do not attempt to change the systems they pass through. However, as th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reverse Engineering
Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so. It is essentially the process of opening up or dissecting a system to see how it works, in order to duplicate or enhance it. Depending on the system under consideration and the technologies employed, the knowledge gained during reverse engineering can help with repurposing obsolete objects, doing security analysis, or learning how something works. Although the process is specific to the object on which it is being performed, all reverse engineering processes consist of three basic steps: Information extraction, Modeling, and Review. Information extraction refers to the practice of gathering all relevant information for performing the operation. Modeling refers to th ...

IP Address
An Internet Protocol address (IP address) is a numerical label such as that is connected to a computer network that uses the Internet Protocol for communication.. Updated by . An IP address serves two main functions: network interface identification and location addressing. Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number. However, because of the growth of the Internet and the depletion of available IPv4 addresses, a new version of IP (IPv6), using 128 bits for the IP address, was standardized in 1998. IPv6 deployment has been ongoing since the mid-2000s. IP addresses are written and displayed in human-readable notations, such as in IPv4, and in IPv6. The size of the routing prefix of the address is designated in CIDR notation by suffixing the address with the number of significant bits, e.g., , which is equivalent to the historically used subnet mask . The IP address space is managed globally by the Internet Assigned Numbers Authority (IA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
