Detection Engineering: Build Robust Programs & Best

Your SOC probably already has detections. The problem is that many of them don't behave like a managed security capability. They behave like a pile of alerts. Analysts close noisy rules because they have to protect their queue. Engineers keep adding logic because coverage gaps are real. Leaders ask whether the program is improving, and the usual answers are weak. Alert counts go up. Tuning tickets pile up.

Episode 18 - Live Fire Defense at Locked Shields

In this episode, host Richard Bejtlich sits down with Corelight Senior Sales Engineers Adam Donadeo and Nico Roosenboom to unpack their firsthand experiences at Locked Shields, the world’s largest international live-fire cyber defense exercise. The conversation dives deep into the chaotic, real-world friction of defending a massive virtualized network alongside 4,000 global experts against aggressive red team waves.

Vect and TeamPCP partner for ransomware campaigns

Counter Threat Unit (CTU) researchers investigated two interconnected threat groups known as Vect and TeamPCP. The two groups announced a formal operational partnership in late March 2026 to combine TeamPCP’s credential harvesting and data theft capabilities with Vect’s ransomware deployment infrastructure in a widespread campaign involving supply chain attacks and the extortion of multiple organizations.

What is CEN/TS 18099? A guide to the injection attack detection standard

For years, the dominant threat against remote identity verification was the presentation attack: someone holding a printed photo up to a camera, wearing a mask, or playing a pre-recorded video on a phone screen. The industry responded with increasingly sophisticated anti-spoofing technology and vision-based detection models, and the standards to test their effectiveness followed. But many of today’s most sophisticated fraudsters don’t bother with the camera at all.

What the Black Hat NOC taught me about MCP & agentic SOCs (Chapter 1 of 4)

The first time an MCP (Model Context Protocol) server felt real to me, it wasn't because of a clean demo. It was because of the noise. TL;DR: The harness matters more than the protocol, and the evidence matters more than both. MCP earns its keep when it shortens the path from a good security question to trustworthy evidence, and almost everything interesting about making that work happens in the harness wrapped around the model. In this series, I will cover how to build an MCP for an AI SOC.

A double-edged bleeding edge: Classifying AI threats

Sophos X-Ops presents a working taxonomy for attacks using, and targeting, AI Conversations about ‘AI threats’ typically collapse into one of two extremes. On the one hand, hype: unverified claims that don’t hold up to scrutiny and invite significant criticism. On the other, dismissal: it’s just old tradecraft with new branding.

AI Powered Threat Detection: CISO's Guide

The market is giving CISOs a blunt signal. AI-powered threat detection and response was valued at USD 5.59 billion in 2024 and is projected to reach USD 23.52 billion by 2032, at a 20.00% CAGR according to Kings Research on the AI-powered threat detection and response market. That kind of growth doesn't happen because security teams like new tooling. It happens because modern environments generate more telemetry than analysts can realistically review, and attackers move faster than rule updates.

Strengthening modern detection with Open NDR and integrated threat intelligence

Adversaries are evolving faster than defenders can respond, and they're weaponizing AI to accelerate their attacks. We’ve seen “living-off-the-land”, lateral movement, and the abuse of legitimate administrator tools enable hackers to hide in plain sight, diluting the effectiveness of traditional detection methods. Meanwhile, defenders are nervously trying to keep up with the accelerating pace of AI-empowered threats hitting them at machine speed.

The Cybersecurity Poverty Line: Why it exists and why Sophos exists to erase it

The Cybersecurity Poverty Line: Why it exists and why Sophos exists to erase it Erase is an ambitious word. We chose it because the agentic era of AI creates a genuine opportunity to change the equation. There are roughly 359 million businesses in the world. Fewer than 35,000 of them employ a CISO. Every framework, product taxonomy, analyst report, compliance regime, and piece of cybersecurity marketing in circulation assumes a senior security leader on the other end.

Episode 17 - Home Labs and Tinted Windows: Why Network Visibility Starts at Your Front Door

In this episode, host Richard Bejtlich and guest Ricky Lin explore the practical—and often personal—side of network defense: monitoring the home network. Ricky shares how he uses Corelight and Zeek to track everything from his children's YouTube habits to the constant chatter of IoT devices like Tesla vehicles and smart appliances. They delve into the "tinted windows" analogy to explain why visibility into encrypted traffic is still possible through network metadata, even when the contents are hidden.
