Evaluating AI systems at Corelight

AI system evaluation is the process of continuously assessing AI system capabilities, limitations, and performance through quantitative and qualitative measures. Across the system lifecycle, evals provide continuous assurance: Validating system behavior before deployment and detecting drift, bias, and reliability issues in production.

Hunting the Undead: Accelerating NetNTLMv1 Lookups Without GPUs

Outdated protocols, forgotten configurations, and legacy dependencies continue to create opportunities for attackers in modern environments. This research explores how NetNTLMv1 can still be leveraged today and how improvements in attack tooling are reducing the cost and complexity of exploiting it.

Episode 21 - Building AI Harnesses to Unify Detection and Response

Corelight Senior Security Engineer Jordan Hair joins Richard Bejtlich to break down how defense teams can leverage agentic AI harnesses to transform traditional security operations. By wrapping deterministic code around large language models, Hare created automated agents for alert triage, threat hunting, and detection engineering that shrink routine investigations from 45 minutes down to seconds.

Securing Black Hat's NOC: Lessons from James Pope of Corelight

Corelight’s James Pope joins Dark Reading’s Joan Goodchild at Black Hat USA to share lessons from more than a decade defending one of cybersecurity’s most unique network environments: the Black Hat Network Operations Center (NOC). As SOC lead for the Black Hat NOC since 2014, James helps oversee more than 100 analysts, threat hunters, and partners tasked with distinguishing legitimate security research from real attacks across a network built from scratch for the conference.

Sophos MDR: Define MDR Contacts in Sophos Central

A step-by-step tutorial showing you how to define your Sophos Managed Detection and Response (MDR) authorized contacts and threat response mode in Sophos Central. As a Sophos MDR customer, assigning authorized contacts lets you fully utilize the service. This instructs the Sophos MDR Operations team who to contact and how to take action during an active threat. You're prompted to take these steps in Sophos Central after activating a new Sophos MDR license, and you can modify this information at any time.

Threat Actor Dark Factory (The Future of Al Hacking?) | The X-Ops Brief

A criminal talked commercial AI models past their guardrails. Then stood up a "company" of AI agents that engineered, tested and refined malware. It began when Sophos analysts found a folder named "test" on an endpoint nobody recognised. Inside was the front end of a machine: Cobalt Strike profiles, a Telegram command channel, a hidden Sliver server behind Cloudflare and scripts written with the help of AI.

ClickFix campaign abuses Deno runtime for infostealer delivery

Counter Threat Unit (CTU) researchers investigated a June 2026 campaign in which threat actors used the Deno JavaScript runtime as a core execution mechanism within a ClickFix-driven intrusion chain. On June 3 and June 4, compromised WordPress sites served Cloudflare-themed ClickFix lures that prompted users to execute a clipboard-delivered PowerShell command. This command initiated an MSI-based staging process that installed Deno and enabled retrieval and execution of remote JavaScript.

Mythos: When Al becomes the attacker, the network becomes the first line of defense.

Cyber defense in the age of Mythos Advanced AI has fundamentally shifted the security landscape, shrinking the window for vulnerability exploitation from weeks to hours. When standard patching workflows can't keep pace, your network becomes your most critical line of defense. In this video, we explore how Corelight transforms network traffic into actionable security insights to power your SOC. The best data drives the best defense. Discover how to improve your SOC outcomes by up to 300% over legacy data.

Cybersecurity Threat Detection: A SOC Guide for 2026

You're probably living this already. Your SIEM is collecting more logs than anyone can read, your endpoint tool is firing alerts that look urgent until they aren't, and someone on the leadership team keeps asking whether the organization is “covered” without defining what covered means. That's the pressure behind cybersecurity threat detection in 2026. Teams don't need another disconnected console.
