Hands-on Labs & Case Studies

When the pod is already dead and the node was recycled, the evidence is not where you are looking for it. This operational guide explains how to reconstruct the incident with mandatory logs, snapshots under quarantine, and memory capture in Kubernetes before the container disappears.

Buying a CSPM does not reduce risk by itself: it can turn it into noise. When everything “is medium” and everything “is urgent”, public S3 alerts stop protecting and start anesthetizing. This operational guide covers why it happens, how to do triage without self-deception, and how to turn alerts into decisions and measurable remediation.

Command injection in enterprise assistants like Copilot and Gemini is not “just prompt injection”: it appears when the model ends up controlling tools, rendering content, or executing flows with privileges. This article grounds the vectors (including JavaScript escape sequences in evaluators), operational signals, and network-level input sanitization with measures applicable in the enterprise.

Operational guide to automate identity isolation in AWS IAM and Azure Entra ID using a centralized webhook (n8n) after detecting an anomalous sign-in: architecture, least privileges, concrete actions, and audit validation.

Technical postmortem of the Storm-2949 case in Azure: how an identity-based chain and abuse of App Services enabled exfiltration of Key Vault secrets and SQL Database data without deploying malware, and which signals and controls failed in corporate environments.

Dirty Frag (CVE-2026-43284) allows, under specific conditions, escalating to root on the AWS EKS node from a compromised container. This article describes the attack surface, operational signals, and how to apply seccomp profiles and validate them in EKS to break the exploitation chain.

Session cookie theft via Adversary-in-the-Middle (AitM) allows an attacker to reuse an already authenticated session in the cloud console, even when the administrator has MFA. This article breaks down operational signals, real business impact, and practical mitigations based on conditional access, network validation, and reducing session surface area.

The supply chain in container registries fails when we treat public base images as “trusted” and when we use mutable tags like :latest. This article grounds the abuse scenario, why a corporate registry is not synonymous with security, and how to operate ECR/ACR/GCR with immutability, push-time scanning, and signature policies (Cosign/Notation) that actually block unsafe deployments.

An attacker with read permissions can avoid a massive SELECT and exfiltrate complete databases by sharing snapshots with an external account or making them temporarily public. This operational guide explains how RDS/EBS and equivalents are abused, which events to look for in logs, and how to block it with guardrails (SCP/Azure Policy) and real-time alerts.

“We encrypt it with KMS” is not a security measure if the default key does not enforce additional controls. Provider-managed encryption often allows implicit decryption for anyone with permissions on the resource. This article debunks the myth and explains how to restrict key usage (CMK) with policies and conditions such as kms:ViaService, and what changes between AWS, Azure, and GCP.
