  • DMARC — Defeating E-Mail Abuse
    CERT-EU Security Whitepaper 17-001 DMARC — Defeating E-Mail Abuse Christos Koutroumpas ver. 1.3 February 9, 2017 TLP: WHITE 1 Preface E-mail is one of the most valuable and broadly used means of communication and most orga- nizations strongly depend on it. The Simple Mail Transport Protocol (SMTP) – the Internet’s underlying email protocol – was adopted in the eighties and is still in use after 35 years. When it was designed, the need for security was not so obvious, and therefore security was not incor- porated in the design of this protocol. As a result, the protocol is susceptible to a wide range of attacks. Spear-phishing campaigns in particular can be more successful by spoofing (altering) the originator e-mail address to imper- sonate a trusted or trustworthy organization or person. This can lead to luring the recipient into giving away credentials or infecting his/her computer by executing malware delivered through the e-mail. While raising user awareness on how to avoid e-mail fraud is recommended, the Verizon Data Breach Investigations Report indicates that more needs to be done. The DBIR report reveals that 30% of all phishing e-mail messages were opened by the recipients and with 12% clicked on the content and executed malicious code. The median time for the first user of a phishing campaign to open the malicious email is 1 minute, 40 seconds. The median time to the first click on the attachment was 3 minutes, 45 seconds. These statistics highlight the risk for an organization on the receiving end of spear-phishing e-mails.

  • What Is SPF? Introduction
    Valimail White Paper February 2018 What is SPF? Introduction Sender Policy Framework (SPF) is a Work on SPF started in 2003, and domains cornerstone of email authentication, and is the have been deploying it increasingly widely first of several standards established for that since then. SPF was published as RFC 4408 purpose. in 2006, and became an officially proposed Internet standard via RFC 7208 in 2014. In a simplistic sense, SPF lets you create a whitelist for IP addresses. If a mail server SPF is widely used by major and minor with an IP address that’s not on your list tries receivers of email (Google, Microsoft, Yahoo, to send email using your domain, it won’t etc.) as well as all Secure Email Gateways pass the SPF authentication test. (SEGs). How It Works The way SPF works is quite simple in principle: For instance, we examined the SPF records for all 62 sponsors of the 2017 1. Domain owners publish SPF records to RSA Conference. We found 58 who had the Domain Name System (DNS) that spell published SPF records, but 17 of those out the rule sets for their domains. An had records with errors in them. That’s SPF record is plain text, and it can be a nearly 30 percent failure rate — and as simple as a single line listing the IP that’s among security companies. addresses that are allowed to send email on the domain’s behalf. Companies that don’t have a lot of expertise in cybersecurity in general (and email 2. When an email server receives an incoming security in particular) often find SPF email, it examines the domain shown in even more tricky.

  • 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.

  • DMARC: Monitor & Secure Your Email Delivery
    Guide DMARC: Monitor & secure your email delivery Chris Nagele Founder of Wildbit postmarkapp.com Read the web version. Do you know every source of email for your domain? Are spammers trying to spoof your email domain for hacking or fraud opportunities? Are you complying with the best email practices to ensure inbox delivery? These are the questions that DMARC answers, giving you full control of email delivery for your company’s domain. At Postmark, email authentication has been extremely important to us from day one. We believe that anyone should be able to easily send emails with proper infrastructure, tools, and email standards without having to pay enterprise prices. DMARC, and our support of it, is a big part of this mission. 2 What is DMARC? DMARC (Domain-based Message Authentication, Reporting & Conformance) is a standard that prevents spammers from using your domain to send email without your permission — also known as spoofing. Spammers can forge the “From” address on messages so the spam appears to come from a user in your domain. A good example of this is PayPal spoofing, where a spammer sends an email to you pretending to be PayPal in an effort to obtain your account information. DMARC ensures these emails get blocked before you even see them in your inbox. In addition, DMARC gives you great visibility and reports into who is sending email on behalf of your domain, ensuring only legitimate email is received. The good news is that DMARC is open and free for anyone to use, allowing you to secure your domain’s emails and gain control of your email delivery.

  • Permanent Email • Spam and Spoofing
    CU eComm Program Permanent Email • Spam and Spoofing We get a lot of inquiries regarding SPAM. As a result, we have compiled a list of the most frequently asked questions with explanations for each. See below. I hope you find this information helpful. SPAM FAQ Is the alumni association sending me spam? No. Neither the alumni association nor Harris Internet Services, who host the Alumni Connections servers that maintain the email forwarding service, are the source of the spam. We respect your privacy and do not sell, or otherwise distribute, alumni email addresses; nor have they been stolen. How did the spammers get my address? Unfortunately, there are many ways that spammers obtain email addresses: addresses compiled by commercial entities from web commerce; web crawlers searching for specific domain names (such as @alumni.anyschool.edu) on any web site where contact information might be listed; and a practice sometimes called "blind spamming" or "dictionary spamming" in which spammers simply guess at the username before the @ sign and send literally thousands of messages. This is why you may see a message addressed to "albert@, allen@, andrew@ ...," etc. The spammers run what is basically a dictionary of usernames against a domain • those that don't immediately bounce are kept and reused. This can give the false impression that the spammer has access to the list of user accounts. Viruses can also generate unwanted email and harvest addresses for spammers. Even if your computer is not infected, if someone else has your address in their address book and their computer becomes infected, viruses will often send multiple messages to everyone in the address book.
