In one week, critical PHP flaws put web servers at risk, Node.js patched a bug that can lead to code execution, attackers exploited self-hosted apps, and a malicious LiteLLM release went out through official channels. Here’s how I keep track of my own AI tools, apps and repositories, and the daily prompt I use.
Impact of the eMudhra CA compromise: How one weak link can make fake websites and software look real. Why security updates and post-quantum preparation matter now
