Cybersecurity

As a DevSecOps Team Leader, my job is to secure customers using modern technologies. Sounds straightforward, right? The reality is far more complex. Every day, I face the challenge of enabling innovation while maintaining security. The rapid adoption of AI has introduced a new dimension to this challenge: agentic AI assistants that do not just chat, they act. This challenge connects directly to something I wrote about recently. In my article on spec-driven development with GitHub Spec-Kit, I discussed how structure and governance matter when using AI for coding. The same principle applies here: when AI agents can execute code, access secrets, and operate with user privileges, we need structure and governance more than ever. ...

The recent Notepad++ supply chain compromise shows how even widely trusted, open-source tools become vectors for state-sponsored espionage when their distribution infrastructure falls into the wrong hands. This was a surgical, six-month operation that bypassed traditional code security controls by exploiting the update mechanism. What Happened and Where the SDLC Failed In 2025, Notepad++, a widely used open-source text editor, suffered a sophisticated supply chain attack. Chinese state-sponsored threat actors compromised the shared hosting provider in June, gaining control of the update distribution system. Even after losing direct server access in September following a kernel update, attackers maintained persistence through stolen credentials until December 2. The fixed version 8.8.9 with hardened update verification was released on December 9. ...

What is ClawdBot/MoltBot/OpenClaw? For those unfamiliar with the project, OpenClaw (formerly MoltBot, previously ClawdBot) is a personal AI assistant platform that integrates with multiple messaging channels including WhatsApp, Telegram, Discord, Slack, Signal, iMessage, and many others. The project is available at github.com/openclaw/openclaw and maintains a website at openclaw.ai. The tool is designed to be a “local-first, single-user assistant” with capabilities that include shell command execution, filesystem operations, browser automation, and integration with various cloud services. It’s essentially a bridge between AI models and your entire digital ecosystem. However, OpenClaw does not provide model access itself; users must configure it with their own API keys from providers like Anthropic, OpenAI, or others. ...

MITRE released the 2025 CWE Top 25 on December 11, 2025, identifying the most dangerous software weaknesses based on 39,080 CVE Records published between June 2024 and June 2025. The list ranks weaknesses by their frequency as root causes in CVE data and their CVSS severity scores, highlighting persistent threats like XSS and SQL Injection alongside emerging issues such as authorization flaws and memory bugs—key priorities for DevSecOps teams securing modern cloud‑native applications. Explore how the 2025 rankings differ from 2024, the top ten shifts, and what CWE root causes reveal beyond CVE trends. ...

Like your favorite music streaming service’s 2025 Wrapped®, here’s my recap of Kubernetes security highlights from 2025, plus predictions for features likely graduating to stable in early 2026. As a DevSecOps Team Leader, I bridge development speed with security rigor daily. Kubernetes and cloud-native security are my passion, especially hardening workloads for production. With Kubernetes v1.35 releasing December 17, now’s the perfect time to review 2025’s security wins and plan for 2026. ...

In today’s fast-paced tech landscape, it’s common to find incredibly talented engineers mastering complex orchestrators like Kubernetes or crafting intricate Infrastructure as Code solutions. We’re living in an era of high-level abstractions, which is fantastic for productivity. However, this focus on the ’new and shiny’ can sometimes lead us to overlook the foundational bedrock upon which everything is built. It might seem a bit old-school to write a blog post about hardening SSH in 2025. Yet, these ‘basic’ skills are more critical than ever. In a world of ephemeral infrastructure and complex supply chains, securing the front door to our systems remains a non-negotiable first step. ...

In the rapidly evolving landscape of AI and large language models (LLMs), the ability to connect these models to external tools and data sources is crucial for building powerful, automated applications. The Model Context Protocol (MCP) has emerged as a standard for this purpose, but its use also introduces new security challenges. This article explores how to work securely with third-party MCP servers, drawing insights from the recently released OWASP GenAI security cheatsheet. ...

On November 5th, 2025, a set of high-severity vulnerabilities in runc were publicly disclosed, allowing for full container breakouts. Runc is the cornerstone of containerization on Linux, serving as the default low-level container runtime for industry-standard tools like Docker, Podman, and Kubernetes. Its ubiquity means that a vulnerability in runc has far-reaching implications for the entire cloud-native ecosystem. This post summarizes the vulnerabilities, the affected versions, and the recommended actions to mitigate them. ...

As Halloween approaches and the days grow shorter, it’s the perfect time for a spooky story… or, in my case, a recap of what’s been brewing in my professional life! With the end of the year lurking around the corner, it’s time to take stock of the exciting changes, challenging projects, and community efforts that have made 2025 a year to remember. So, grab your pumpkin-spiced latte, and let’s dive into the cauldron of the last few months. ...

Today, my manager forwarded me this article about several zero-day CVEs discovered in CyberArk and HashiCorp products. After some time spent researching online, I confirmed that both brands have fixed these CVEs by releasing updated versions!! I’m not surprised that these two big corporations acted quickly and fixed the vulnerabilities; both are well-known and reliable! This event gave me an excuse to write this article and respond to one of the most common questions I get from my customers whenever I share news about a new release of a secrets manager: ...
