Legacy tokens and Global Admin impersonation in Entra ID: real surface, abuse, and operational control

Legacy tokens (including “actor” patterns in S2S flows) and the use of obsolete APIs such as Azure AD Graph have been a dangerous combination: they enable privileged operations without going through the same guardrails we now expect (MFA and Conditional Access). This article breaks down how Global Admin impersonation materializes in Entra ID, what signals to look for, and how to run it in practice to close the gap.

GCP Vertex AI and “Bucket Squatting” (CVE-2026-2473): when guessing a bucket is enough to compromise MLOps pipelines

“Bucket squatting” in GCP around Vertex AI (CVE-2026-2473) showed a dangerous pattern: if a pipeline trusts predictable Cloud Storage names and does not validate bucket ownership/identity, an attacker can create that bucket first and force malicious uploads/reads, leading to remote execution and model poisoning. This article breaks down the scenario, operational signals, and mitigations applicable in enterprises.

Identity theft in AWS: The main threat in 2026

In 2026, most initial intrusions in AWS do not start with an exploit, but with stolen credentials and sessions. This article explains why it happens (including the 83% identity-focused figure), what operational signals reveal it in AWS, and how to harden IAM/STS without breaking corporate operations.

Session cookie theft (AitM) in Cloud consoles: why MFA won’t save you and how to put real guardrails in place

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.

Secrets management in Kubernetes: the Base64 problem

Native Kubernetes Secrets do not “encrypt”: they encode in Base64. In corporate environments this translates into exposure via logs, overly broad RBAC, etcd without encryption, and pipelines that leak credentials. How to understand the real risk and operate External Secrets Operator with Azure Key Vault or AWS Secrets Manager without breaking deployment.

Denial of Wallet Attacks: when the goal is not to take down your service, but to ruin your bill (FinOps Security)

Denial of Wallet (DoW) exploits cloud elasticity to force consumption and drive up costs: cryptomining, massive scaling, artificial traffic, and abuse of managed services. This article breaks down real signals, containment, and operational guardrails (quotas, anomaly alerts, IAM) to reduce economic impact without breaking operations.
