Security experts have been talking about Kerberoasting for over a decade, yet this attack continues to evade typical defense methods. Why? It's because existing detections rely on brittle heuristics and static rules, which don't hold up for detecting potential attack patterns in highly variable Kerberos traffic. They frequently generate false positives or miss "low-and-slow" attacks altogether.  Is there a better and more accurate way for modern organizations to detect subtle anomalies within irregular Kerberos traffic? The BeyondTrust research team sought to answer this question by combining security research insights with advanced statistics. This article offers a high-level look into the driving forces behind our research and our process of developing and testing a new statistical framework for improving Kerberos anomaly detection accuracy and reducing false positives. An Introduction to Kerberoasting Attacks  Kerberoasting attacks take advantage of the Kerberos netwo...

By 2025, Zero Trust has evolved from a conceptual framework into an essential pillar of modern security. No longer merely theoretical, it's now a requirement that organizations must adopt. A robust, defensible architecture built on Zero Trust principles does more than satisfy baseline regulatory mandates. It underpins cyber resilience, secures third-party partnerships, and ensures uninterrupted business operations. In turn, more than 80% of organizations plan to implement Zero Trust strategies by 2026, according to a recent Zscaler report .  In the context of Zero Trust, artificial intelligence (AI) can assist greatly as a tool for implementing automation around adaptive trust and continuous risk evaluation. In a Zero Trust architecture, access decisions must adapt continuously to changing factors such as device posture, user behavior, location, workload sensitivity, and more. This constant evaluation generates massive volumes of data, far beyond what human teams can process alo...

The modern-day threat landscape requires enterprise security teams to think and act beyond traditional cybersecurity measures that are purely passive and reactive, and in most cases, ineffective against emerging threats and sophisticated threat actors. Prioritizing cybersecurity means implementing more proactive, adaptive, and actionable measures that can work together to effectively address the threats that most affect your business. Ideally, these measures should include the implementation of a Continuous Threat Exposure Management (CTEM) program, Vulnerability Management, and Attack Surface Management (ASM), which are all very different from one another, yet overlap. With CTEM , vulnerability management, and ASM, it's not a question of which one is "better" or "more effective", as they complement each other uniquely. By adopting all three, security teams get the continuous visibility and context they need to proactively boost defenses, giving them a le...

AI agents promise to automate everything from financial reconciliations to incident response. Yet every time an AI agent spins up a workflow, it has to authenticate somewhere; often with a high-privilege API key, OAuth token, or service account that defenders can't easily see. These "invisible" non-human identities (NHIs) now outnumber human accounts in most cloud environments, and they have become one of the ripest targets for attackers. Astrix's Field CTO Jonathan Sander put it bluntly in a recent Hacker News webinar : "One dangerous habit we've had for a long time is trusting application logic to act as the guardrails. That doesn't work when your AI agent is powered by LLMs that don't stop and think when they're about to do something wrong. They just do it." Why AI Agents Redefine Identity Risk Autonomy changes everything: An AI agent can chain multiple API calls and modify data without a human in the loop. If the underlying credential is exposed or overprivileged, each addit...

With nearly 80% of cyber threats now mimicking legitimate user behavior, how are top SOCs determining what's legitimate traffic and what is potentially dangerous? Where do you turn when firewalls and endpoint detection and response (EDR) fall short at detecting the most important threats to your organization? Breaches at edge devices and VPN gateways have risen from 3% to 22%, according to Verizon's latest Data Breach Investigations report. EDR solutions are struggling to catch zero-day exploits, living-off-the-land techniques, and malware-free attacks. Nearly 80% of detected threats use malware-free techniques that mimic normal user behavior, as highlighted in CrowdStrike's 2025 Global Threat Report. The stark reality is that conventional detection methods are no longer sufficient as threat actors adapt their strategies, using clever techniques like credential theft or DLL hijacking to avoid discovery.  In response, security operations centers (SOCs) are turning to a multi-lay...

Despite years of investment in Zero Trust, SSE, and endpoint protection, many enterprises are still leaving one critical layer exposed: the browser. It's where 85% of modern work now happens. It's also where copy/paste actions, unsanctioned GenAI usage, rogue extensions, and personal devices create a risk surface that most security stacks weren't designed to handle. For security leaders who know this blind spot exists but lack a roadmap to fix it, a new framework may help. The Secure Enterprise Browser Maturity Guide: Safeguarding the Last Mile of Enterprise Risk , authored by cybersecurity researcher Francis Odum, offers a pragmatic model to help CISOs and security teams assess, prioritize, and operationalize browser-layer security. It introduces a clear progression from basic visibility to real-time enforcement and ecosystem integration, built around real-world threats, organizational realities, and evolving user behavior. Why the Browser Has Become the Security Blind Spot Over ...

Security operations centers (SOCs) are under pressure from both sides: threats are growing more complex and frequent, while security budgets are no longer keeping pace. Today's security leaders are expected to reduce risk and deliver results without relying on larger teams or increased spending. At the same time, SOC inefficiencies are draining resources. Studies show that up to half of all alerts are false positives, with some reports citing false positive rates as high as 99 percent . This means highly trained analysts spend a disproportionate amount of time chasing down harmless activity, wasting effort, increasing fatigue, and raising the chance of missing real threats. In this environment, the business imperative is clear: maximize the impact of every analyst and every dollar by making security operations faster, smarter, and more focused. Enter the Agentic AI SOC Analyst The agentic AI SOC Analyst is a force multiplier that enables organizations to do more with the team an...

New research has uncovered continued risk from a known security weakness in Microsoft's Entra ID , potentially enabling malicious actors to achieve account takeovers in susceptible software-as-a-service (SaaS) applications. Identity security company Semperis, in an analysis of 104 SaaS applications, found nine of them to be vulnerable to Entra ID cross-tenant nOAuth abuse. First disclosed by Descope in June 2023, nOAuth refers to a weakness in how SaaS applications implement OpenID Connect ( OIDC ), which refers to an authentication layer built atop OAuth to verify a user's identity. The authentication implementation flaw essentially allows a bad actor to change the mail attribute in the Entra ID account to that of a victim's and take advantage of the app's "Log in with Microsoft" feature to hijack that account. The attack is trivial, but it also works because Entra ID permits users to have an unverified email address, opening the door to user imperson...

Hackers never sleep, so why should enterprise defenses? Threat actors prefer to target businesses during off-hours. That's when they can count on fewer security personnel monitoring systems, delaying response and remediation. When retail giant Marks & Spencer experienced a security event over Easter weekend, they were forced to shut down their online operations, which account for approximately a third of the retailer's clothing and home sales. As most staff are away during off-hours and holidays, it takes time to assemble an incident response team and initiate countermeasures. This gives attackers more time to move laterally within the network and wreak havoc before the security team reacts. While not every organization may be ready to staff an in-house team around the clock, building a 24/7 SOC remains one of the most robust and proactive ways to protect against off-hours attacks. In the rest of this post, we'll explore why 24/7 vigilance is so important, the challenges ...

Introduction: Security at a Tipping Point Security Operations Centers (SOCs) were built for a different era, one defined by perimeter-based thinking, known threats, and manageable alert volumes. But today's threat landscape doesn't play by those rules. The sheer volume of telemetry, overlapping tools, and automated alerts has pushed traditional SOCs to the edge. Security teams are overwhelmed, chasing indicators that often lead nowhere, while real risks go unnoticed in the noise. We're not dealing with a visibility problem. We're dealing with a relevance problem. That's where Continuous Threat Exposure Management (CTEM) comes in. Unlike detection-centric operations that react to what's already happened, CTEM shifts the focus from what could happen to "why it matters." It's a move away from reacting to alerts and toward managing risk with targeted, evidence-based actions. The Problem with Alert-Centric Security At its core, the SOC is a monitoring engine. It digests input from f...

AI is changing everything — from how we code, to how we sell, to how we secure. But while most conversations focus on what AI can do, this one focuses on what AI can break — if you're not paying attention. Behind every AI agent, chatbot, or automation script lies a growing number of non-human identities — API keys, service accounts, OAuth tokens — silently operating in the background. And here's the problem: 🔐 They're invisible 🧠 They're powerful 🚨 They're unsecured In traditional identity security, we protect users. With AI, we've quietly handed over control to software that impersonates users — often with more access, fewer guardrails, and no oversight. This isn't theoretical. Attackers are already exploiting these identities to: Move laterally through cloud infrastructure Deploy malware via automation pipelines Exfiltrate data — without triggering a single alert Once compromised, these identities can silently unlock critical systems. You don't get a second cha...

In today's security landscape, budgets are tight, attack surfaces are sprawling, and new threats emerge daily. Maintaining a strong security posture under these circumstances without a large team or budget can be a real challenge. Yet lean security models are not only possible - they can be highly effective. River Island, one of the UK's leading fashion retailers, offers a powerful case study on how to do more with less. As River Island's InfoSec Officer, Sunil Patel and his small team of three are responsible for securing over 200 stores, an e-commerce platform, a major distribution center, and head offices. With no headcount growth on the horizon, Sunil had to rethink how security could scale effectively. By adopting a lean security model, powered by Intruder's exposure management platform , the team was able to improve visibility, respond faster to threats, and empower others across the business to fix what matters most. Here are five key lessons from thei...

The evolution of cyber threats has forced organizations across all industries to rethink their security strategies. As attackers become more sophisticated — leveraging encryption, living-off-the-land techniques, and lateral movement to evade traditional defenses — security teams are finding more threats wreaking havoc before they can be detected. Even after an attack has been identified, it can be hard for security teams to prove to auditors that they have fully mitigated the issues that allowed the attackers in. Security teams worldwide have prioritized endpoint detection and response (EDR), which has become so effective that threat actors have changed their tactics to avoid attack vectors protected by host-based defenses. These advanced threats are particularly vexing for critical infrastructure providers in financial services , energy and utilities , transportation , and government agencies that may have proprietary systems that cannot be protected by traditional endpoint securi...
