GuardDuty is the default-on threat-detection service in AWS — and sophisticated adversaries actively engineer their operations to avoid triggering its findings. This article catalogues nine specific evasion techniques observed in cloud incident response, and ships the hunt patterns that surface the silence itself.
Adversaries are increasingly weaponising AWS KMS for ransomware — encrypting victim data with attacker-controlled keys, modifying key policies to lock out the legitimate owner, and using grant tokens for stealth access. This hunt playbook covers the techniques, the detection logic, and the response actions for KMS-mediated ransomware.
CloudTrail is the cornerstone of AWS threat detection — but it has structural blind spots adversaries deliberately exploit. This guide maps 12 places CloudTrail does not log by default, the techniques that abuse each gap, and the compensating hunt patterns that fill the visibility hole.
A 15-month career roadmap for SOC analysts transitioning to threat hunters — five phases of three months each (Mindset, Telemetry, Tradecraft, Hunts, Portfolio), with weekly cadences, success metrics, common pitfalls, and FAQ for working analysts.
