Email Security | Breaking Cybersecurity News | The Hacker News

For years, our industry has treated "blocking" as the gold standard. If the email didn't land, if the malware didn't execute, if the alert fired in the SIEM, we called it a win. That mindset made sense in a world where most attacks came through a handful of familiar doors. But AI has changed the game. We're not dealing with hobbyists sending out clumsy phishing attacks anymore. Modern adversaries are running multi‑channel, AI‑assisted businesses at machine speed. And if all you're doing is blocking at the edge, you're not really defending. You're just delaying. Generative AI has made it trivial to spin up highly personalized, multi‑step social engineering campaigns that operate simultaneously across email, collaboration apps, mobile, social media, and paid media. The result is a social engineering attack chain : a sequence of stages designed to manufacture trust, erode judgment, and bypass brittle controls. You don't beat that by tuning another filter. You have to disrupt the at...

Launching a ransomware attack used to take real effort. Now, thanks to AI, almost anyone can launch a sophisticated attack, which changes the game for everyone responsible for protecting businesses. Reconnaissance that once took hours now takes minutes. Phishing emails that used to require careful crafting can now be generated at scale and sent to hundreds of targets simultaneously. IBM's 2025 Cost of a Data Breach Report found that AI reduced the time required to create phishing emails from 16 hours to just 5 minutes. For MSPs managing dozens or hundreds of clients, and for internal IT teams holding the line across an entire organization, understanding how AI is changing ransomware is key to staying ahead of the threat and minimizing disruption when attacks occur. The attack that starts in the inbox Before attackers can encrypt files or demand a ransom, they first need a way into the organization. One of the easiest ways to get that access is by tricking someone into cli...

BEC accounted for over $3 billion in reported losses last year alone. Most organizations don't realize they're exposed until it's too late. Here's how to tell if your defenses have gaps. Business email compromise doesn't announce itself. There's no ransomware splash screen, no locked files, no dramatic system outage. Instead, a finance team member processes what looks like a routine vendor payment update. A controller wires funds based on what appears to be a CFO's direct request. By the time anyone notices, the money is gone. The FBI IC3's 2024 Internet Crime Report documented $55 billion in cumulative BEC losses over the past decade, with $3 billion in 2024 alone — making it the most financially destructive enterprise-targeted cyber threat in the country. The challenge with BEC is that it exploits trust, not technology. These attacks carry no malicious payload for a gateway to catch — just carefully crafted messages designed to manipulate human judgment. That makes traditional de...

Phishing emails have reached a point where they can fool both people and the tools designed to stop them. For anyone working through a packed inbox, it's easy to trust what looks familiar and click without a second thought. What's worrying is that phishing is rarely the end goal. It's usually the entry point for something much bigger: a ransomware attack. Once attackers gain access, they don't act immediately. They move through systems, map connections, and prepare the environment. By the time ransomware is deployed, it's the final step — not the first. To stay ahead, you need protection at two critical points. An advanced email security solution that catches even the most stealthy phishing attempts, and a strong BCDR strategy that lets you restore data quickly and avoid paying a ransom if something slips through. Why phishing remains so effective Phishing works because it plays on human behavior. Email may seem like a simple communication tool, but it functions as a decision-mak...

For security leaders, the inbox remains the front door for attackers. Here's why the smartest teams are adding adaptive, AI-driven protection to their cloud email security, not replacing them. Email is still the number-one attack vector for enterprises, and it is not even close. The FBI's Internet Crime Complaint Center reported that business email compromise alone generated $3 billion in losses in 2024 , with AI-enabled attacks accelerating the trend ( FBI IC3 Report ). The attacks that succeed today don't carry obvious malicious payloads. They rely on trust, tone, and timing; a spoofed vendor sending a "routine" invoice update, or a convincing impersonation of a CEO with an urgent request. No malware. No suspicious links. Just words, carefully chosen. Microsoft 365 is the backbone of productivity for most organizations, and Microsoft Defender and Exchange Online Protection do solid work catching known spam, malware, and co...

The conversation around AI in the SOC has mostly centered on efficiency: closing alerts faster, reducing queue backlog, and automating repetitive work that burns out L1 analysts. That framing is directionally right, and it matters because analyst fatigue is real. For teams dealing with high alert volume, analysts are often asked to make good decisions under a fragmented context and time pressure. But that framing is still incomplete. The bigger shift is not just workflow automation or orchestration of predefined playbooks. It is AI's ability to perform contextual, hypothesis-driven investigation across multiple telemetry sources, work that has traditionally depended on experienced L2 or L3 analysts and limited human time. When that capability can be applied consistently across every alert, it changes the operating model, not just the speed of the existing one. Two recent investigations at Prophet Security make that real. In both cases, the attacks were not obvious from signature-bas...

Here's what keeps me up at night. Not zero-days. Not sophisticated nation-state attacks. What worries me is the backlog. Every MSP has one. The list of security configurations that need fixing. The policies have been sitting in "report only" mode since last year. The E5 features that clients are paying for but nobody's turned on because it might break something. The app registrations with excessive permissions from three years ago that nobody's audited. The conditional access policies that need updating but keep getting pushed to next quarter. We all know this backlog exists. We tell ourselves we'll get to it. But quarters turn into years, and that backlog just grows. Meanwhile, AI attackers don't have a backlog. They have automation. Most breaches in Microsoft 365 won't start with a zero-day. They'll start with a setting that's been in "report only" for two years. Example tenant: critical Conditional Access policies exist but a...

The cybersecurity community has been buzzing about JPMorgan Chase CISO Pat Opet's open letter to third-party suppliers since its release right before RSA. This candid assessment from the security leader of one of the world's largest financial institutions has struck a chord, particularly his observations about SaaS security. Opet didn't mince words: " SaaS models are fundamentally reshaping how companies integrate services and data—a subtle yet profound shift eroding decades of carefully architected security boundaries ." This statement encapsulates a reality that security professionals have been grappling with—the traditional security perimeter has dissolved, replaced by a complex web of interconnected SaaS applications, each with their own configurations, access controls, and data sharing capabilities. Let's break down the key issues highlighted in Opet's letter and explore practical solutions. The New SaaS Security Challenges OAuth Vulnerabiliti...
