    This opinion piece critiques the 50-in-5 Digital Public Infrastructure initiative, a global campaign supported by organizations including the United Nations and the Gates Foundation to accelerate adoption of digital identity systems, payment rails, and interoperable public digital infrastructure. The article frames DPI as a potential mechanism for centralized technocratic control and argues that the expansion of digital identity and data-sharing systems raises broader concerns about governance, surveillance, and individual autonomy.

    This tutorial extends a production-grade GitHub Actions pipeline by adding layered security scanning with Gitleaks, Semgrep, and Trivy, followed by an AI synthesis stage powered by GPT-4o. Rather than overwhelming engineers with raw scanner output, the pipeline consolidates findings into structured Slack incident reports that prioritize exploitability, remediation effort, and deployment risk.

  • Defense-in-Depth in a Tiny Supabase App: 5 Patterns I Baked Into Altair Before Open-Sourcing It

    This story was originally published on HackerNoon at: https://hackernoon.com/defense-in-depth-in-a-tiny-supabase-app-5-patterns-i-baked-into-altair-before-open-sourcing-it.


    Before I flipped my Supabase PSA tool public, I had to convince myself a fork couldn't ship a security hole. Here are the five patterns that made me trust it.

    I open-sourced a Supabase PSA tool last week. To trust the click, I layered five auth patterns — middleware JWT check, withAuth wrappers, role-scoped column whitelists, CI-enforced architecture, and RLS — so any single layer failing wouldn't matter. Plus the one mistake I almost shipped: a service-role key in client code.

  • Claude Mythos Marks a Turning Point for AI Cybersecurity and Everyday Network Privacy

    This story was originally published on HackerNoon at: https://hackernoon.com/claude-mythos-marks-a-turning-point-for-ai-cybersecurity-and-everyday-network-privacy.


    Frontier AI models are beginning to automate exploit development, compressing vulnerability weaponization timelines from weeks into hours.

    Anthropic's Claude Mythos Preview can autonomously find zero-days and write working exploits across every major OS and browser — a capability jump so significant they're not releasing it publicly. The window between vulnerability disclosure and weaponization is shrinking fast, and static CVSS-based prioritization frameworks aren't built for that world. Patch faster, reduce your logged network surface, and assume comparable capabilities will be in adversaries' hands within 18 months.

  • We Are Scaling AI Capability Faster Than We Are Scaling Comprehension

    This story was originally published on HackerNoon at: https://hackernoon.com/we-are-scaling-ai-capability-faster-than-we-are-scaling-comprehension.


    At AICCONS 2026, Okta’s Arun Kumar Elengovan warns: AI is advancing faster than we understand it. Here’s why foundations matter more than ever.

    Arun Kumar Elengovan argues modern AI is scaling faster than human understanding. At AICCONS 2026, he breaks AI down to three fundamentals—representation, learning, and reasoning—warning that models don’t learn truth, only patterns. As systems evolve into agents, risks shift from answers to actions, making security, interpretability, and guardrails essential for building trustworthy AI.

    SecureCallOps is a phone outreach platform built for volunteer phone-banking, where callers receive one contact at a time instead of a full spreadsheet. It encrypts personal data at rest, renders names as images, keeps phone numbers out of the browser, and enforces single-assignment workflows server-side. Built with FastAPI, PostgreSQL, Docker Compose, and Terraform for Azure. After using it internally, I cleaned it up and open-sourced it.

  • Security Audit Finds RCE Risks in 6.2% of MCP Servers

    This story was originally published on HackerNoon at: https://hackernoon.com/security-audit-finds-rce-risks-in-62percent-of-mcp-servers.


    An automated security audit of 2,000+ MCP servers reveals that 6.2% expose LLMs to Remote Code Execution (RCE) and data exfiltration. Here is the full report.

    We audited over 2,000 open-source Model Context Protocol (MCP) servers and found that 6.2% contain critical architectural flaws. Developers are exposing dangerous tools like subprocess.run and raw SQL executors directly to LLMs without Human-in-the-Loop (HitL) confirmations. This turns a simple prompt injection into a full host Remote Code Execution (RCE) or database wipe. It's time to shift from wrapper scripts to Agentic DevSecOps.
