For many organisations, these defences are simply no longer enough.\u00a0<\/p>\n\n\n\n<p>At Dionach, we see this reality firsthand. Across penetration tests, adversary simulations, and threat-led assessments, email continues to be one of the most common footholds for attackers. Whether through credential harvesting, MFA fatigue, misconfigured mail rules, or compromised third-party accounts, email compromise often becomes the\u00a0<em>starting point<\/em>\u00a0for much larger breaches.\u00a0<\/p>\n\n\n\n<p>And the statistics paint a clear picture:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>91% of cyber-attacks start with email<\/strong>, according to multiple industry studies (<a href=\"https:\/\/www.darkreading.com\/endpoint-security\/91-of-cyberattacks-start-with-a-phishing-email\" target=\"_blank\" rel=\"noreferrer noopener\">Dark Reading<\/a>).\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Business Email Compromise (BEC)<\/strong>\u00a0losses exceeded\u00a0<strong>$2.9 billion in a single year<\/strong>\u00a0(<a href=\"http:\/\/chrome-extension:\/\/efaidnbmnnnibpcajpcglclefindmkaj\/https:\/\/www.ic3.gov\/annualreport\/reports\/2023_ic3report.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">FBI IC3 Report<\/a>).\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A significant portion\u00a0of\u00a0Dionach\u2019s\u00a0assessments uncover issues related to misconfigured email security settings, weak authentication, open forwarding rules, or deficient behavioural controls (aggregated internal insight, anonymised).\u00a0<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Why Traditional Email Security Tools Are Failing<\/strong><\/h2>\n\n\n\n<p>Most organisations rely on the same mix of controls they\u2019ve used for years:<br>Secure Email Gateways (SEGs), signature-based filters, URL analysis, malware scanning, and user training. These measures are important but they\u2019re no longer effective against modern attacks.<\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>1. Most modern phishing attacks contain <em>no<\/em> malware or malicious links<\/strong><\/h4>\n\n\n\n<p>Attackers increasingly use \u201cclean\u201d emails:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Impersonation of suppliers<\/li>\n\n\n\n<li>Fake invoice requests<\/li>\n\n\n\n<li>OAuth token abuse<\/li>\n\n\n\n<li>Compromised internal mailboxes<\/li>\n\n\n\n<li>Social engineering without payloads<\/li>\n<\/ul>\n\n\n\n<p>Traditional tools can\u2019t detect these because there\u2019s nothing technically malicious inside the message.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>2. Email security often focuses only on inbound threats<\/strong><\/h4>\n\n\n\n<p>But attackers exploit:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Internal accounts taken over<\/li>\n\n\n\n<li>Third-party vendor compromises<\/li>\n\n\n\n<li>Lateral mailbox-to-mailbox phishing<\/li>\n<\/ul>\n\n\n\n<p>Many solutions offer limited visibility into internal or supplier behaviour.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>3. SEGs can&#8217;t detect when a <em>legitimate<\/em> account is misused<\/strong><\/h4>\n\n\n\n<p>Once attackers gain access to a real mailbox, their activity looks \u201cnormal\u201d to traditional filters.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>4. Misconfigurations are more common than organisations realise<\/strong><\/h4>\n\n\n\n<p>Dionach frequently identifies weaknesses such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Incomplete or missing MFA<\/li>\n\n\n\n<li>Weak conditional access policies<\/li>\n\n\n\n<li>Inadequate DMARC, SPF, DKIM deployment<\/li>\n\n\n\n<li>Legacy authentication still enabled<\/li>\n\n\n\n<li>Auto-forwarding rules to external mailboxes<\/li>\n\n\n\n<li>Insecure OAuth app permissions<\/li>\n<\/ul>\n\n\n\n<p>These misconfigurations create easy pathways for attackers, and most are invisible to users.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The Evolving Email Threat Landscape<\/strong><\/h2>\n\n\n\n<p>Modern email attacks are no longer obvious or signature based. Attackers have shifted to low-signal, high-impact techniques designed to mimic legitimate behaviour:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Impersonation of executives or third-party suppliers<\/strong><\/li>\n\n\n\n<li><strong>Account takeover leading to internal phishing sequences<\/strong><\/li>\n\n\n\n<li><strong>Vendor and supply-chain compromise<\/strong><\/li>\n\n\n\n<li><strong>Fraudulent invoice redirection<\/strong><\/li>\n\n\n\n<li><strong>AI-enhanced phishing that mirrors writing style and tone<\/strong><\/li>\n<\/ul>\n\n\n\n<p>These threats aren\u2019t detectable with traditional filters. They don\u2019t contain malicious links, malware attachments, or known indicators of compromise. Instead, they exploit trust.<\/p>\n\n\n\n<p>Healthcare providers, financial institutions, and public-sector organisations face this risk acutely. With limited security resources and high volumes of sensitive communication, even a single compromised mailbox can escalate into a major incident.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><img data-recalc-dims=\"1\" fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"627\" src=\"https:\/\/i0.wp.com\/www.dionach.com\/wp-content\/uploads\/2025\/11\/AdobeStock_1583224918-1024x627.jpeg?resize=1024%2C627&#038;ssl=1\" alt=\"\" class=\"wp-image-25553\" style=\"width:813px;height:auto\" srcset=\"https:\/\/i0.wp.com\/dionach.com\/wp-content\/uploads\/2025\/11\/AdobeStock_1583224918.jpeg?resize=1024%2C627&amp;ssl=1 1024w, https:\/\/i0.wp.com\/dionach.com\/wp-content\/uploads\/2025\/11\/AdobeStock_1583224918.jpeg?resize=300%2C184&amp;ssl=1 300w, https:\/\/i0.wp.com\/dionach.com\/wp-content\/uploads\/2025\/11\/AdobeStock_1583224918.jpeg?resize=768%2C470&amp;ssl=1 768w, https:\/\/i0.wp.com\/dionach.com\/wp-content\/uploads\/2025\/11\/AdobeStock_1583224918.jpeg?resize=1536%2C941&amp;ssl=1 1536w, https:\/\/i0.wp.com\/dionach.com\/wp-content\/uploads\/2025\/11\/AdobeStock_1583224918.jpeg?w=2048&amp;ssl=1 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Introducing Abnormal Security: A New Approach to Email Protection<\/strong><\/h2>\n\n\n\n<p>After years of observing the limitations of traditional email security tools, new behavioural-driven platforms have emerged and one of the most innovative is <strong><a href=\"https:\/\/abnormal.ai\/\" target=\"_blank\" rel=\"noreferrer noopener\">Abnormal Security<\/a><\/strong>.<\/p>\n\n\n\n<p>Nomios (Dionach\u2019s parent group) has partnered with Abnormal because it brings a fundamentally different approach to the problem.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What makes Abnormal different?<\/strong><\/h2>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>1.
