Orbia CISO Miranda Ritchie on building security into sustainable infrastructure

In this interview with Help Net Security, industrial cybersecurity, CISO at Orbia, talks about protecting industrial systems where software runs water, chemical and manufacturing processes. She explains why a cyber incident in these settings can harm people, equipment and the environment, and how spread-out sites and aging control hardware widen the risk. Ritchie describes tying security to safety culture, embedding cyber teams early in new projects, and treating nothing as trusted just because it sits … More → The post Orbia CISO Miranda Ritchie on building security into sustainable infrastructure appeared first on Help Net Security.

20 open-source cybersecurity tools to keep your team ready for anything

AI is changing how security teams find vulnerabilities, analyze code, test applications, and protect infrastructure. Developers are building tools to secure AI systems themselves, from coding agents and memory protection to model exposure discovery. This roundup covers recent open-source releases for vulnerability research, application security testing, container security, endpoint protection, AI security, and penetration testing. AIMap: Open-source tool finds and tests exposed AI endpoints Public-facing Ollama servers, MCP endpoints, and inference proxies have multiplied across … More → The post 20 open-source cybersecurity tools to keep your team ready for anything appeared first on Help Net Security.

macOS is becoming a proving ground for AI agents

Somewhere right now, a Mac Mini is sitting on a shelf doing someone’s chores. Nobody’s watching it. It reads a version number out of Terminal, hops over to Safari, digs up a release year, then quietly files a reminder, the kind of dull three-app errand a human would grumble through in ninety seconds. The machine just works, hour after hour, an AI agent with hands on the keyboard and no one in the room. That … More → The post macOS is becoming a proving ground for AI agents appeared first on Help Net Security.

How to implement a continuous offensive security testing program

The hard part was never finding the exposure. It was deciding what to do about it: whether to patch, mitigate, monitor, or accept, and banking that that decision would still hold tomorrow. A penetration test answers this question for the day it runs, then quietly expires. The environment shifts, a control drifts, a new technique lands, and the report now describes a network that no longer exists. That gap, between finding an exposure and trusting … More → The post How to implement a continuous offensive security testing program appeared first on Help Net Security.

OpenAI and Anthropic are pulling in different directions

Companies are handing routine operational decisions to AI agents that plan, remember, and act on their behalf. These agents run on statistical models, and their behavior can drift across weeks and months. That drift opens a security gap outside the reach of standard monitoring tools. A study of about 1,080 open job postings at OpenAI and Anthropic maps where the two largest AI labs are taking this technology. Each role reflects a budget decision, so … More → The post OpenAI and Anthropic are pulling in different directions appeared first on Help Net Security.

Incredible new material makes heat programmable

A newly developed material can control and “program” heat, allowing it to direct thermal radiation, switch modes, and remember its settings without continuous power. The innovation could lead to smarter infrared sensors, better energy technologies, and memory devices that use light and heat instead of electrical charges.
