Open Proxy
An open proxy is a type of proxy server that is accessible by any Internet user. Generally, a proxy server only allows users within a network group (i.e. a closed proxy) to store and forward Internet services such as Domain Name System, DNS or web pages to reduce and control the bandwidth (computing), bandwidth used by the group. With an open proxy, however, any user on the Internet can use this forwarding service. Advantages An anonymous open proxy is useful to those looking for online anonymity and privacy, as it can help users hide their IP address from web servers since the server requests appear to originate from the proxy server. It makes it harder to reveal their identity and thereby helps preserve their perceived security while browsing World Wide Web, the web or using other internet services. Real anonymity and extensive internet security might not be achieved by this measure alone as website operators can use Client (computing), client-side scripts to determine the brow ...

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 exploiting the advantages 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 thro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Security
Internet security is a branch of computer security. It encompasses the Internet, browser security, web site security, and network security as it applies to other applications or operating systems as a whole. Its objective is to establish rules and measures to use against attacks over the Internet. The Internet is an inherently insecure channel for information exchange, with high risk of intrusion or fraud, such as phishing, online viruses, trojans, ransomware and worms. Many methods are used to combat these threats, including encryption and ground-up engineering. Threats Emerging Threats Emerging cyberthreats are a result of recent technological breakthroughs. For example, deepfakes use AI to produce audio and video that seems real but are actually fake, which increases the danger of fraud and false information. Furthermore, traditional risks can be automated and strengthened by AI-driven attacks, making them harder to identify and neutralize. Malicious software Maliciou ...

Open Mail Relay
An open mail relay is a Simple Mail Transfer Protocol (SMTP) server configured in such a way that it allows anyone on the Internet to send e-mail through it, not just mail destined to or originating from known users. This used to be the default configuration in many mail servers; indeed, it was the way the Internet was initially set up, but open mail relays have become unpopular because of their exploitation by spammers and worms. Many relays were closed, or were placed on blacklists by other servers. History and technology Until the 1990s, mail servers were commonly intentionally configured as open relays; in fact, this was frequently the installation default setting. The traditional store and forward method of relaying e-mail to its destination required that it was passed from computer to computer (through and beyond the Internet) via modems on telephone lines. For many early networks, such as UUCPNET, FidoNet and BITNET, lists of machines that were open relays were a co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anonymizing Proxy
An anonymizer or an anonymous proxy is a tool that attempts to make activity on the Internet untraceable. It is a proxy server computer that acts as an intermediary and privacy shield between a client computer and the rest of the Internet. It accesses the Internet on the user's behalf, protecting personal information of the user by hiding the client computer's identifying information such as IP addresses. Anonymous proxy is the opposite of transparent proxy, which sends user information in the connection request header. Commercial anonymous proxies are usually sold as VPN services. Purposes There are many reasons for using anonymizers, such as minimizing risk, prevention of identity theft, or protecting search histories from public disclosure. Some countries apply heavy censorship on the internet. Anonymizers can help to allow free access to all of the internet content, but they cannot help against persecution for accessing the anonymizer website itself. Furthermore, as in ...

SORBS
Sorbs (; ; ; ; ; also known as Lusatians, Lusatian Serbs and Wends) are a West Slavs, West Slavic ethnic group predominantly inhabiting the parts of Lusatia located in the German states of Germany, states of Saxony and Brandenburg. Sorbs traditionally speak the Sorbian languages (also known as "Wendish" and "Lusatian"), which are closely related to Czech language, Czech and Lechitic languages. Upper Sorbian and Lower Sorbian are officially recognized minority languages in Germany. In the Early Middle Ages, the Sorbs formed their own principality, which later shortly became part of the early West Slavic Samo's Empire and Great Moravia, as were ultimately conquered by the East Francia (Sorbian March) and Holy Roman Empire (Saxon Eastern March, Margravate of Meissen, March of Lusatia). From the High Middle Ages, they were ruled at various times by the closely related History of Poland during the Piast dynasty, Poles and Kingdom of Bohemia, Czechs, as well as the more distant Germa ...

NJABL
Not Just Another Bogus List (NJABL) was a DNS blacklist. NJABL maintained a list of known and potential spam sources ( open mail relays, open proxies, open form to mail HTTP gateways, dynamic IP pools, and direct spammers) for the purpose of being able to tag or refuse e-mail and thereby block spam from certain sources. NJABL automatically retests only listed open relays every 90 days. The Open Proxy IPs portion (only) of NJABL data was used in Spamhaus XBL list NJABL's dynamic IP list originally came from Dynablock but was maintained independently since Dynablock stopped updating December 2003.

Composite Blocking List
In computer networking, the Composite Blocking List (CBL) is a DNS-based Blackhole List of suspected E-mail spam sending computer infections. Overview The CBL takes its source data from very large spamtraps/mail infrastructures, and only lists IPs exhibiting characteristics such as: * Open proxies of various sorts (HTTP, socks, AnalogX, wingate etc.) * Worms/viruses/ botnets that do their own direct mail transmission, or are otherwise participating in a botnet. * Trojan horse In Greek mythology, the Trojan Horse () was a wooden horse said to have been used by the Greeks during the Trojan War to enter the city of Troy and win the war. The Trojan Horse is not mentioned in Homer, Homer's ''Iliad'', with the poem ending ... or "stealth" spamware. The CBL attempts to avoid listing real mail servers, but certain misconfigurations of mail servers can make the system appear infected (for example, servers that send HELO with 'localhost' or a similar incorrect domain.)

AHBL
The Abusive Hosts Blocking List (AHBL) was an internet abuse tracking and filtering system developed by The Summit Open Source Development Group, and based on the original Summit Blocking List (2000–2002). Its DNSBLs were shut down on Jan 1, 2015 and now appear to be blacklisting the entire Internet. DNSbl and RHSbl lists The AHBL operated several DNSbl lists and one RHSbl list for use in various types of services. While the data were mostly added and removed automatically, the AHBL preferred to manage certain categories by hand for accuracy. The DNSbl list was developed for use in SMTP services and was a real-time blocking system. This means that data were collected from various sources 24 hours a day, 7 days a week in real time, and merged into the database. The data included spam sources, open proxies, open relays, DDoS drones, Usenet spam sources, and the controversial Shoot On Sight listing policy. The IRCbl list was a reduced version of the DNSbl that does not inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DNSBL
A Domain Name System blocklist, Domain Name System-based blackhole list, Domain Name System blacklist (DNSBL) or real-time blackhole list (RBL) is a service for operation of mail servers to perform a check via a Domain Name System (DNS) query whether a sending host's IP address is blacklisted for email spam. Most mail server software can be configured to check such lists, typically rejecting or flagging messages from such sites. A DNSBL is a software mechanism, rather than a specific list or policy. Dozens of DNSBLs exist. They use a wide array of criteria for listing and delisting addresses. These may include listing the addresses of zombie computers or other machines being used to send spam, Internet service providers (ISPs) who willingly host spammers, or those which have sent spam to a honeypot system. Since the creation of the first DNSBL in 1998, the operation and policies of these lists have frequently been controversial, both in Internet advocacy circles and occasion ...

Software
Software consists of computer programs that instruct the Execution (computing), execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware. The introduction of high-level programming languages in 1958 allowed for more human-readable instructions, making software development easier and more portable across different computer architectures. Software in a programming language is run through a compiler or Interpreter (computing), interpreter to execution (computing), execute on the architecture's hardware. Over time, software has become complex, owing to developments in Computer network, networking, operating systems, and databases. Software can generally be categorized into two main types: # operating systems, which manage hardware resources and provide services for applicat ...
