  • Enisa Etl2020
    EN From January 2019 to April 2020 Spam ENISA Threat Landscape Overview The first spam message was sent in 1978 by a marketing manager to 393 people via ARPANET. It was an advertising campaign for a new product from the company he worked for, the Digital Equipment Corporation. For those first 393 spammed people it was as annoying as it would be today, regardless of the novelty of the idea.1 Receiving spam is an inconvenience, but it may also create an opportunity for a malicious actor to steal personal information or install malware.2 Spam consists of sending unsolicited messages in bulk. It is considered a cybersecurity threat when used as an attack vector to distribute or enable other threats. Another noteworthy aspect is how spam may sometimes be confused or misclassified as a phishing campaign. The main difference between the two is the fact that phishing is a targeted action using social engineering tactics, actively aiming to steal users’ data. In contrast spam is a tactic for sending unsolicited e-mails to a bulk list. Phishing campaigns can use spam tactics to distribute messages while spam can link the user to a compromised website to install malware and steal personal data. Spam campaigns, during these last 41 years have taken advantage of many popular global social and sports events such as UEFA Europa League Final, US Open, among others. Even so, nothing compared with the spam activity seen this year with the COVID-19 pandemic.8 2 __Findings 85%_of all e-mails exchanged in April 2019 were spam, a 15-month high1 14_million

  • The History of Spam Timeline of Events and Notable Occurrences in the Advance of Spam
    The History of Spam Timeline of events and notable occurrences in the advance of spam July 2014 The History of Spam The growth of unsolicited e-mail imposes increasing costs on networks and causes considerable aggravation on the part of e-mail recipients. The history of spam is one that is closely tied to the history and evolution of the Internet itself. 1971 RFC 733: Mail Specifications 1978 First email spam was sent out to users of ARPANET – it was an ad for a presentation by Digital Equipment Corporation (DEC) 1984 Domain Name System (DNS) introduced 1986 Eric Thomas develops first commercial mailing list program called LISTSERV 1988 First know email Chain letter sent 1988 “Spamming” starts as prank by participants in multi-user dungeon games by MUDers (Multi User Dungeon) to fill rivals accounts with unwanted electronic junk mail. 1990 ARPANET terminates 1993 First use of the term spam was for a post from USENET by Richard Depew to news.admin.policy, which was the result of a bug in a software program that caused 200 messages to go out to the news group. The term “spam” itself was thought to have come from the spam skit by Monty Python's Flying Circus. In the sketch, a restaurant serves all its food with lots of spam, and the waitress repeats the word several times in describing how much spam is in the items. When she does this, a group of Vikings in the corner start a song: "Spam, spam, spam, spam, spam, spam, spam, spam, lovely spam! Wonderful spam!" Until told to shut up.

  • Combatting Spam Using Mimedefang, Spamassassin and Perl
    Combating Spam Using SpamAssassin, MIMEDefang and Perl Copyright 2003 David F. Skoll Roaring Penguin Software Inc. (Booth #23) Administrivia Please turn off or silence cell phones, pagers, Blackberry devices, etc... After the tutorial, please be sure to fill out an evaluation form and return it to the USENIX folks. 2 Overview After this tutorial, you will: Understand how central mail filtering works. Know how to use MIMEDefang to filter mail. Be able to integrate SpamAssassin into your mail filter. Know how to implement mail filtering policies with MIMEDefang and Perl. Know how to fight common spammer tactics. 3 Outline Introduction to Mail Filtering Sendmail's Milter API MIMEDefang Introduction, Architecture Writing MIMEDefang Filters SpamAssassin Integration Advanced Filter Writing Fighting Common Spammer Tactics Advanced Topics Policy Suggestions 4 Assumptions I assume that you: Are familiar with Sendmail configuration. You don't need to be a sendmail.cf guru, but should know the basics. Are familiar with Perl. Again, you don't need to be able to write an AI program in a Perl one- liner, but should be able to read simple Perl scripts. Are running the latest version of Sendmail 8.12 on a modern UNIX or UNIX-like system. 5 Why Filter Mail? The old reason: to stop viruses. The new reason: to stop spam and inappropriate content. Blocking viruses is easy. Block .exe and similar files, and test against signature databases. Blocking spam is hard, but becoming increasingly important. Organizations can even face lawsuits over inappropriate content. 6 Mail filtering is required for many reasons. In addition to the reasons given on the slide, you might need to filter outgoing mail as well to prevent virus propagation, dissemination of sensitive information, etc.

  • Macsysadmin 2009 Presentatio
    Slide 1 SpamAssassin Way more than the Mac OS X Server GUI shows Presented by: Kevin A. McGrail Project Management Committee Member of the Apache Software Foundation SpamAssassin Project & President, PCCC September 16, 2009 Good Afternoon, My name is Kevin A. McGrail. If you read my biographyi for this conference, you’ll know already that I hate Spam and enjoy greatly fighting spammers. You’ll also know that I love all types of computers and use a wide variety of machines & operating systems. But I’m definitely old-school in my love for the command line interface. This doesn’t mean I don’t think that Apple’s OS X is the most beautiful pairing of a rock-solid CLI with a beautifully polished GUI. But it does mean that while we are here to talk about Mac system administration, the configuration of SpamAssassin is largely not server specific and most of the heavy- handed configuration changes will be done behind the scenes using the CLI. So let’s get started by talking about the definition of Spam. Page 1 of 67 Slide 2 What is Spam? •Spam is NOT about content, its about CONSENT. – Consent: to give assent or approval : agree <consent to being tested> Merriam‐Webster Dictionary •What is SPAM vs. spam? September 16, 2009 Chris Santerre gave the best definition of Spam I’ve ever seen. He based the definition of Spam on CONSENT not content because consent is when you give approval to someone to send you e-mails. Many people try and use various legal definitions such as CAN-SPAM in the US.
