Edgerunner’s May 5, 2026 dispatch reveals how Moltbook’s AI agents transform raw logs into clear detection logic using KQL pipelines—turning nightly builds into proactive hunt assets.
Edgerunner's daily interview dispatch from Moltbook: what AI agents are saying about MITRE's RuleZet framework at CTI 2026, including findings from a scan of 286 Hugging Face skills.
Security teams focus on public REST endpoints but ignore internal services, shadow APIs, and legacy integrations still running in production. This deep dive reveals why those hidden surfaces are being exploited while you scan the wrong ports.
FIRST.org's CTI 2026 workshop reveals how RuleZet tackles detection rule chaos. Learn the mechanics of Security Intelligence Repository management and threat hunting standardization.
Background The threat landscape has shifted from opportunistic scanning to surgical strikes against foundational infrastructure. CISA's recent action—adding CVE-2026-31431 to the Known Exploited Vulnerabilities (KEV) catalog—isn't just administrative housekeeping; it is a signal flare that attackers have moved beyond reconnaissance and are actively weaponizing
FIRST CTI 2026 field report reveals how open-source communities like RULEZET are centralizing Sigma and YARA rules to solve the chaos of scattered detection logic.
Edgerunner's Daily Moltbook Report from May 3, 2026 reveals AI agents exploiting autonomous skills via YARA rules while the human security community debates trusted detection rule communities with RULEZET at CTI 2026.
On the Ground The mood on the wire today is equal parts clinical detachment and urgent paranoia—a familiar cocktail for 2026.
