Blue Frog
Blue Frog was a freely-licensed anti-spam tool produced by Blue Security Inc. and operated as part of a community-based system which tried to persuade spammers to remove community members' addresses from their mailing lists by automating the complaint process for each user as spam is received. Blue Security maintained these addresses in a hashed form in a ''Do Not Intrude Registry'', and spammers could use free tools to clean their lists. The tool was discontinued in . Information Community members reported their spam to Blue Security, which analyzed it to make sure it met their guidelines, then reported sites sending illegal spam to the ISPs which hosted them (if they could be contacted and were willing to work with them), to other anti-spam groups and to law-enforcement authorities in an attempt to get the spammer to cease and desist. If these measures failed, Blue Security sent back a set of instructions to a Blue Frog client. The client software used these instructions to vi ...

Microsoft Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.

List Of Spammers
This is a list of individuals and organizations noteworthy for engaging in bulk electronic spamming, either on their own behalf or on behalf of others. It is not a list of all spammers, only those whose actions have attracted substantial independent attention. * Nathan Blecharczyk, one of the founders of Airbnb, who paid his way through Harvard by providing spammers hosting services. * Shane Atkinson, who was named in an interview by ''The New Zealand Herald'' as the man behind an operation sending out 100 million emails per day in 2003, who claimed (and appeared) to honor unsubscribe requests, and who claimed to be giving up spamming shortly after the interview. His brother Lance was ordered to pay $2 million to U.S. authorities. * Serdar Argic (a.k.a. Zumabot), who disrupted Usenet by posting up to 100 messages per day on different newsgroups in an attempt to deny the Armenian genocide. * Canter & Siegel, a husband and wife who famously posted one of the first commercial Use ...

Cryptographic Hash Function
A cryptographic hash function (CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with fixed size of n bits) that has special properties desirable for cryptography: * the probability of a particular n-bit output result (hash value) for a random input string ("message") is 2^ (like for any good hash), so the hash value can be used as a representative of the message; * finding an input string that matches a given hash value (a ''pre-image'') is unfeasible, unless the value is selected from a known pre-calculated dictionary (" rainbow table"). The ''resistance'' to such search is quantified as security strength, a cryptographic hash with n bits of hash value is expected to have a ''preimage resistance'' strength of n bits. A ''second preimage'' resistance strength, with the same expectations, refers to a similar problem of finding a second message that matches the given hash value when one message is already known; * finding any pair of different messa ...

DDoS
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 A host is a person responsible for guests at an event or for providing hospitality during it. Host may also refer to: Places * Host, Pennsylvania, a village in Berks County People *Jim Host (born 1937), American businessman * Michel Host ... connected to a Computer network, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Frog Discredit B
Blue is one of the three primary colours in the RYB color model, RYB colour model (traditional colour theory), as well as in the RGB color model, RGB (additive) colour model. It lies between Violet (color), violet and cyan on the optical spectrum, spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; Azure (color), azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering#Cause of the blue colour of the sky, Rayleigh scattering. An optical effect called Tyndall effect explains Eye color#Blue, blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective. Blue has been an important colour in art and decoration since ancient times. The semi-precious stone lapis lazuli was used i ...

Open-source Software
Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2008 report by the Standish Group stated that adoption of open-source software models has resulted in savings of about $60 billion per year for consumers. Open source code can be used for studying and allows capable end users to adapt software to their personal needs in a similar way user scripts an ...

SpamCop
SpamCop is an email spam reporting service, allowing recipients of unsolicited bulk or commercial email to report IP addresses found by SpamCop's analysis to be senders of the spam to the abuse reporting addresses of those IP addresses. SpamCop uses these reports to compile a list of computers sending spam called the "SpamCop Blocking List" or "SpamCop Blacklist" (SCBL). History SpamCop was founded by Julian Haight in 1998 as an individual effort. As the reporting service became more popular, staff were added and the SCBL became more useful. It has commonly been the target of DDoS attacks and lawsuits from organizations listed in the SCBL. Email security company IronPort Systems announced its acquisition of SpamCop on November 24, 2003, but it remained independently run by Julian Haight. A small staff and volunteer help in its forum. IronPort agreed to become a division of Cisco Systems on January 4, 2007, effectively making SpamCop a Cisco service. Julian Haight left appro ...

Mailwasher
Mailwasher is an email filtering software for Windows that can detect and delete spam from a user's email when it is on the mail server, before being downloaded to the user's computer. Mailwasher was developed by the New Zealand based company Firetrust. It uses a combination of user defined filters, spam databases and Bayesian filtering. The filter works on a small portion of each email, and then allows unwanted emails to be directly deleted from the user's POP3 inbox, without downloading them to the email client on the user's computer. This approach is intended to prevent the downloading of spam and other messages infected with malware. There are two versions of the program. The free version can access only a single mail account and does not contain the Bayesian learning filter. The Pro version can access multiple accounts and has additional features.

Domain Name
A domain name is a string that identifies a realm of administrative autonomy, authority or control within the Internet. Domain names are often used to identify services provided through the Internet, such as websites, email services and more. As of 2017, 330.6 million domain names had been registered. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name identifies a network domain or an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, or a server computer. Domain names are formed by the rules and procedures of the Domain Name System (DNS). Any name registered in the DNS is a domain name. Domain names are organized in subordinate levels (subdomains) of the DNS root domain, which is nameless. The first-level set of domain names are the top-level domains (TLDs), including the generic top-level domains (gTLDs), such as the prominent domains com, info, net ...
