Weekly Cyber News Rollup, November 28th, 2025

This is your weekly cyber news roll-up for the week ending November 27th, 2025. This week revolves around quiet dependencies turning into loud problems, from abandoned calendar links that can be hijacked to analytics and customer platforms leaking sensitive context. You will hear about a breach at an OpenAI analytics vendor that exposes who is building on artificial intelligence, A I, projects and a ransomware hit on Asahi and Iberia that mixes large data leaks with operational disruption and reputational damage. Developers face a heavy supply chain week as poisoned npm packages, GitHub workflows, and a self spreading JavaScript worm target build systems and secrets. At the same time, flaws in logging agents, emergency alert platforms, and Ray powered A I clusters show how core infrastructure can be hijacked for stealth access, cryptomining, or simply going dark when people need it most. Across the full set of stories, the focus is on how attackers exploit trusted tools and identity layers that many teams treat as background plumbing. You will hear how spyware vendors are turning secure messaging users into targets, how years of pasting code into online tools has quietly exposed live credentials, and how flaws in Oracle identity, Azure Bastion, and Grafana can hand over powerful access with a few crafted requests. Website and endpoint risks also feature, from W three Total Cache and FortiWeb to seven zip, reminding teams that small utilities and plugins can still open big doors. The episode is designed for executives, security teams, builders, and students who need a fast weekly sweep of the real attack surface, stitched across cloud, identity, and software factories, available at DailyCyber.news. By the end, you will have a clear sense of where your own quiet dependencies might be hiding.
