KnujOn ("no junk" spelled backwards, and pronounced "new john") was a project involved in Internet security. KnujOn targeted spam at its root, attacking the illicit activities that spammers derive their revenue from. [1] To that end, KnujOn ran an automated spam reporting tool.
KnujOn was founded in 2005 by Garth Bruen and his father, Dr. Robert Bruen. A multi-purpose software tool called KnujOn was presented at The Northeast Chapter of the High Technology Crime Investigation Association (HTCIA) in November 2005. That software, designed to filter junk mail and produce complaints that may result in the shutdown of scam websites, tracked Internet-based scams and built profiles of persons or organizations engaged in suspicious Internet activity by gathering and sorting large amounts of data. [2]
KnujOn.com collected spam samples from the public, not to build better filters or blacklists, but rather to use them for illicit site termination, test the Internet's policy infrastructure, and gather important statistics. Their general goal was to target advertised illicit transaction sites and hopefully take the financial incentive out of the spam cycle.[ citation needed ]
The service stopped accepting new subscriptions and email submissions on 8 March 2018, and starting from that date, email submissions began bouncing. Eventually, on 22 May 2018, the service was completely shut down.[ citation needed ]
Spamming is the use of messaging systems to send multiple unsolicited messages (spam) to large numbers of recipients for the purpose of commercial advertising, non-commercial proselytizing, or any prohibited purpose, or simply repeatedly sending the same message to the same user. While the most widely recognized form of spam is email spam, the term is applied to similar abuses in other media: instant messaging spam, Usenet newsgroup spam, Web search engine spam, spam in blogs, wiki spam, online classified ads spam, mobile phone messaging spam, Internet forum spam, junk fax transmissions, social spam, spam mobile apps, television advertising and file sharing spam. It is named after Spam, a luncheon meat, by way of a Monty Python sketch about a restaurant that has Spam in almost every dish in which Vikings annoyingly sing "Spam" repeatedly.
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 whitelist or allowlist is a list or register of entities that are being provided a particular privilege, service, mobility, access or recognition. Entities on the list will be accepted, approved and/or recognized. Whitelisting is the reverse of blacklisting, the practice of identifying entities that are denied, unrecognized, or ostracized.
Various anti-spam techniques are used to prevent email spam.
Cybercrime encompasses a wide range of criminal activities that are carried out using digital devices and/or networks. These crimes involve the use of technology to commit fraud, identity theft, data breaches, computer viruses, scams, and expanded upon in other malicious acts. Cybercriminals exploit vulnerabilities in computer systems and networks to gain unauthorized access, steal sensitive information, disrupt services, and cause financial or reputational harm to individuals, organizations, and governments.
Phishing is a form of social engineering and a scam where attackers deceive people into revealing sensitive information or installing malware such as viruses, worms, adware, or ransomware. Phishing attacks have become increasingly sophisticated and often transparently mirror the site being targeted, allowing the attacker to observe everything while the victim navigates the site, and transverses any additional security boundaries with the victim. As of 2020, it is the most common type of cybercrime, with the FBI's Internet Crime Complaint Center reporting more incidents of phishing than any other type of cybercrime.
Stephen John "Steve" Linford is a British entrepreneur and anti-spam campaigner best known for founding The Spamhaus Project.
Email spam, also referred to as junk email, spam mail, or simply spam, is unsolicited messages sent in bulk by email (spamming). The name comes from a Monty Python sketch in which the name of the canned pork product Spam is ubiquitous, unavoidable, and repetitive. Email spam has steadily grown since the early 1990s, and by 2014 was estimated to account for around 90% of total email traffic.
Naive Bayes classifiers are a popular statistical technique of e-mail filtering. They typically use bag-of-words features to identify email spam, an approach commonly used in text classification.
Internet fraud is a type of cybercrime fraud or deception which makes use of the Internet and could involve hiding of information or providing incorrect information for the purpose of tricking victims out of money, property, and inheritance. Internet fraud is not considered a single, distinctive crime but covers a range of illegal and illicit actions that are committed in cyberspace. It is differentiated from theft since, in this case, the victim voluntarily and knowingly provides the information, money or property to the perpetrator. It is also distinguished by the way it involves temporally and spatially separated offenders.
Email fraud is intentional deception for either personal gain or to damage another individual using email as the vehicle. Almost as soon as email became widely used, it began to be used as a means to defraud people, just as telephony and paper mail were used by previous generations.
The Spamhaus Project is an international organisation based in the Principality of Andorra, founded in 1998 by Steve Linford to track email spammers and spam-related activity. The name spamhaus, a pseudo-German expression, was coined by Linford to refer to an internet service provider, or other firm, which spams or knowingly provides service to spammers.
Online advertising, also known as online marketing, Internet advertising, digital advertising or web advertising, is a form of marketing and advertising that uses the Internet to promote products and services to audiences and platform users. Online advertising includes email marketing, search engine marketing (SEM), social media marketing, many types of display advertising, and mobile advertising. Advertisements are increasingly being delivered via automated software systems operating across multiple websites, media services and platforms, known as programmatic advertising.

A spoofed URL involves one website masquerading as another, often leveraging vulnerabilities in web browser technology to facilitate a malicious computer attack. These attacks are particularly effective against computers that lack up-to-date security patches. Alternatively, some spoofed URLs are crafted for satirical purposes.

The history of email spam reaches back to the mid-1990s when commercial use of the internet first became possible - and marketers and publicists began to test what was possible.
SmartScreen is a cloud-based anti-phishing and anti-malware component included in several Microsoft products:
The online distribution of counterfeit medicines has been growing during the last decades. The role of Internet as an unregulated medicine market is the main reasons behind this phenomenon, especially the effectiveness of "spam" as a tool for advertising and promoting these products. Websites and social media are new powerful instruments that organized criminal groups could exploit to conduct their illicit businesses. The spread of this emerging threat worldwide poses a very high risk for the health and safety of unaware consumers.
