Exploring the Hugging Face Breach: mapping AI agent tactics to Elastic Defend
Every stage of the Hugging Face breach maps to Elastic Defend and SIEM rules already shipping, from worker RCE and credential harvest to self-migrating C2 and GenAI detection.

Detecting Tycoon 2FA AiTM attacks across Entra ID and Google Workspace
Tycoon 2FA bypasses MFA on Entra ID and Google Workspace. We map telemetry fingerprints across both platforms, ship detection rules for both tiers, and contain incidents in under 10 seconds with Elastic Workflows.

CI/CD pipeline abuse: the problem no one is watching
How we built an open-source, drop-in CI template that uses signal extraction and LLM reasoning to catch CI/CD abuse in GitHub Actions, GitLab CI, and Azure DevOps pipelines.

Beyond Behaviors: AI-Augmented Detection Engineering with ES|QL COMPLETION
Learn how Elastic's ES|QL COMPLETION command brings LLM reasoning directly into detection rules, enabling detection engineers to build intelligent alert triage without external orchestration.

Misbehaving Modalities: Detecting Tools, Not Techniques
We explore the concept of Execution Modality and how modality-focused detections can complement behaviour-focused ones.

AWS SNS Abuse: Data Exfiltration and Phishing
During a recent internal collaboration, we dug into publicly known SNS abuse attempts and our knowledge of the data source to develop detection capabilities.

Linux Detection Engineering - The Grand Finale on Linux Persistence
By the end of this series, you'll have a robust knowledge of both common and rare Linux persistence techniques; and you'll understand how to effectively engineer detections for common and advanced adversary capabilities.

Emulating AWS S3 SSE-C Ransom for Threat Detection
In this article, we’ll explore how threat actors leverage Amazon S3’s Server-Side Encryption with Customer-Provided Keys (SSE-C) for ransom/extortion operations.

Linux Detection Engineering - Approaching the Summit on Persistence Mechanisms
Building on foundational concepts and techniques explored in the previous publications, this post discusses some creative and/or complex persistence mechanisms.

Announcing the Elastic Bounty Program for Behavior Rule Protections
Elastic is launching an expansion of its security bounty program, inviting researchers to test its SIEM and EDR rules for evasion and bypass techniques, starting with Windows endpoints. This initiative strengthens collaboration with the security community, ensuring Elastic’s defenses remain robust against evolving threats.

Linux Detection Engineering - A Continuation on Persistence Mechanisms
This document continues the exploration of Linux detection engineering, emphasizing advancements in monitoring persistence mechanisms. By building on past practices and insights, it provides a roadmap for improving detection strategies in complex environments.
