Research Report Email Fraud Landscape, Q2 2018
2018 Q2 Email Fraud Landscape The Fake Email Crisis 6.4 Billion Fake Messages Every Day Email Fraud Landscape, Q2 2018 Executive Summary The crisis of fake email continues. Far from being merely a “social engineering” issue, fake email is a direct result of technical issues with the way email is implemented: It lacks a built-in authentication mechanism making it all too easy to spoof senders. However, this problem is also amenable to a technical solution, starting with the email authentication standards DMARC, SPF, and DKIM. For the purposes of this report, Valimail used proprietary data from our analysis of billions of email message authentication requests, plus our analysis of more than 3 million publicly accessible DMARC and SPF records, to compile a unique view of the email fraud landscape. Now in its third consecutive quarter, our report shows how the fight against fake email is progressing worldwide, in a variety of industry categories. Key Findings • 6.4 billion fake emails (with fake From: addresses) are sent worldwide every day • The United States continues to lead the world as a source of fake email • The rate of DMARC implementation continues to grow in every industry • DMARC enforcement remains a major challenge, with a failure rate of 75-80 percent in every industry • The rate of SPF usage continues to grow in every industry • SPF errors remain a significant problem • The U.S. federal government leads all other sectors in DMARC usage and DMARC enforcement www.valimail.com 2 2018 Q2 Email Fraud Landscape Life on Planet Email Email continues to be a robust, effective medium for communications worldwide, and it is both the last remaining truly open network in wide use as well as the largest digital network, connecting half the planet. -

AGARI CYBER INTELLIGENCE DIVISION REPORT H1 2021 Email Fraud & Identity Deception Trends Global Insights from the Agari Identity Graph™ © Copyright 2021 Agari Data, Inc. Executive Summary Call it a case of locking the back window while leaving the front door wide open. A year into the pandemic and amid successful attacks on GoDaddy1, Magellan Health², and a continuous stream of revelations about the SolarWinds “hack of the decade,” cyber-attackers are proving all too successful at circumventing the elaborate defenses erected against them³. But despite billions spent on perimeter and endpoint security, phishing and business email compromise (BEC) scams continue to be the primary attack vectors into organizations, often giving threat actors the toehold they need to wreak havoc. In addition to nearly $7.5 billion in direct losses each year, advanced email threats like the kind implicated in the SolarWinds case⁴ suggest the price tag could be much higher. As corroborated in this analysis from the Agari Cyber Intelligence Division (ACID), the success of these attacks is growing far less reliant on complex technology than on savvy social engineering ploys that easily evade most of the email defenses in use today. Sophisticated New BEC Actors Signal Serious Consequences Credential phishing accounted for 63% of all phishing attacks during the second half of 2020 as schemes related to COVID-19 gave way to a sharp rise in payroll diversion scams, as well as fraudulent Zoom, Microsoft and Amazon alerts targeting millions of corporate employees working from home. Meanwhile, the state- sponsored operatives behind the SolarWinds hack were just a few of the more sophisticated threat actors moving into vendor email compromise (VEC) and other forms of BEC. -

Email doesn't provide any authentication, it is very easy to impersonate and forge emails. • Ransomware is a type of malware that prevents or limits users from accessing their system, either by locking the system's screen or by locking the users' files unless a ransom is paid 8/14/2018 Where does spam come from? • Spam today is sent via “bot-nets”, networks of virus- or worm-infected personal computers in homes and offices around the globe. • Some worms install a backdoor which allows the spammer access to the computer and use it for malicious purposes. • Others steal credentials for public or small company email accounts and send spam from there. • A common misconception is that spam is blocked based on the sending email address. • Spam is primarily identified by sending IP address and content. -
DHS Mandates DMARC for Email Security
Agari U.S. Federal Government DMARC Adoption: DHS Mandates DMARC for Email Security Executive Summary On October 16, 2017, the U.S. Department of Homeland Security issued a Binding Operational Directive (BOD) 18-01 that mandates the implementation of specific security standards to strengthen email and 82% of all Federal domains have no web site security. As part of this directive, all federal agencies that operate DMARC policy .gov email domains must implement a DMARC monitoring policy (p=none) within 90 days. Furthermore, all federal agencies must move to a reject policy (p=reject) by 1 year. Based on Agari research of public DNS records, 82% percent of all US Federal Government domains do not have a DMARC policy, leaving their constituents unprotected from phishing and other forms of email attacks 86% of Federal that impersonate their agency email domains. Cybercriminals exploit this domains that use DMARC choose Agari 1 vulnerability by sending billions of phishing emails per year claiming to be from these government agencies. 1 Includes all domains that send aggregate data to a 3rd party DMARC vendor. 1 | www.agari.com Email Abuse on Federal Agency Domains Phishing continues to be a pervasive threat in the United States and around the world.The impact of these threats has been felt specifically by government agencies. Beyond the high-profile targeted attacks that have made headlines, criminals are executing phishing attacks leveraging the brand name of agencies. Indeed, over the last six months, Agari has seen an amplification of attacks against our Federal customers. As the following chart indicates, on the email-sending and defensive domains that we monitor, 25% of email volume was malicious or failing authentication. -
From SEG to SEC: the Rise of the Next-Generation Secure Email Cloud Executive Summary the Time for Next-Generation Email Security Is Now
WHITE PAPER From SEG to SEC: The Rise of the Next-Generation Secure Email Cloud Executive Summary The Time for Next-Generation Email Security is Now The secure email gateway (SEG) worked for a number of years, but the SEG is no match for a new generation of rapidly evolving advanced The FBI email attacks that use identity deception to trick recipients. With estimates business email compromise scams, spear-phishing attacks, and data breaches, along with other types of crime, cybercriminals are seeing 20,000 massive success to the tune of $2.71 billion each year in the United victims lost States. At the same time that cybercriminals are evolving their tactics, $1.3B businesses are shedding on-premises infrastructure, moving en in 2018 from masse to cloud-based platforms such as Microsoft Office 365 or G business email Suite. These platforms provide native support for anti-spam, virus compromise and malware blocking, email archiving, content filtering, and even sandboxing, but they lack when it comes to protecting against in the United advanced email threats that use identity deception techniques to trick States alone. recipients. This move to cloud-based email and the onslaught of zero-day attacks that successfully penetrate the inbox are shifting email security from signature-based inspection of email on receipt to continuous detection and response using machine learning to detect fraudulent emails and to hunt down latent threats that escaped initial detection or have activated post-delivery. As a result, the Secure Email Cloud has emerged. This AI, graph-based approach detects advanced email attacks and cuts incident response time up to 95% in an effort to reduce the risk of business disruption and the rapidly increasing financial losses from data breaches, ransomware, and phishing. -

This guide will cover the main topics and points of discussion with regard to the mainstream standards used today for authenticating email. The Growth of In an email and spam data report by Cisco Systems, it was revealed Email Spam that over 400 billion spam email messages are sent each day – approximately 85% of worldwide email. This alarmingly high rate of spam being sent out is the direct result of an increase in spamming tactics like phishing, botnets, social engineering, and reputation hijacking. Because spam and other cyber security issues continue to increase year after year, technology integrators have turned to alternative methods to secure their communications. Email authentication is one such method. -
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. -
