Description With the rapidly increasing variety of attack techniques and a simultaneous rise in the number of detection rules offered by EDRs Endpoint Detection and Response and custom-created ones, the need for constant functional testing of detection rules has become evident. However, manually...

CVE-2026-63451

A flaw was found in Suricata, a network Intrusion Detection System. A local user can craft a detection rule that combines frame inspection without content and a transformed match without content. Loading this specially crafted rule can trigger a heap buffer overflow, leading to a denial of servic...

How It's Made: Uncovering Detection Engineering Processes for Network Intrusion Detection Rules

Many Security Operations Centers rely on signature-based Network Intrusion Detection Systems like Suricata, yet detection rule engineering remains understudied. We investigate this process by introducing SuriCap, a platform for rule engineering exercises, and hosting CTF-style workshops where 60...

CTI-REALM: A new benchmark for end-to-end detection rule generation with AI agents

Excerpt: CTI-REALM is Microsoft’s open-source benchmark for evaluating AI agents on real-world detection engineering—turning cyber threat intelligence CTI into validated detections. Instead of measuring “CTI trivia,” CTI-REALM tests end-to-end workflows: reading threat reports, exploring telemetr...

CVE-2026-26939

A flaw was found in Kibana. An authenticated attacker with rule management privileges could exploit a missing authorization vulnerability in the server-side Detection Rule Management. This allows the attacker to configure unauthorized endpoint response actions, such as host isolation, process...
