Today, the National Institute of Standards and Technology (NIST) announced the first standardization of three cryptography schemes that are immune against the threat of quantum computers, known as post-quantum cryptography (PQC) schemes. With these standards, NIST is encouraging computer system administrators to transition as soon as possible.

In the final section of my series on creating a comprehensive security program around Docker [https://nullsweep.com/building-a-docker-security-program], I'll be looking at some ideas and best practices around patching running containers.

In the previous articles, I talked about running static analysis on containers [https://nullsweep.com/docker-static-analysis-with-clair] and rolling

Hmmm ... I'm not sure about this. It's interesting, but I'm not yet convinced about it's place.

Observability 2.0 centers around “wide events,” breaking down the silos between metrics, logs, and traces. This article outlines the core ideas and technical challenges of this new paradigm, and introduces how GreptimeDB, a native open-source database for wide events, provides a unified and efficient foundation for next-gen observability platforms.

While preparing for my Black Hat and DEF CON talks in July of this year, I found the most impactful Entra ID vulnerability that I will probably ever find. One that could have allowed me to compromise every Entra ID tenant in the world (except probably those in national cloud deployments). If you are an Entra ID admin reading this, yes that means complete access to your tenant. The vulnerability consisted of two components: undocumented impersonation tokens that Microsoft uses in their backend for service-to-service (S2S) communication, called “Actor tokens”, and a critical vulnerability in the (legacy) Azure AD Graph API that did not properly validate the originating tenant, allowing these tokens to be used for cross-tenant access.
