ChatGPT advanced account security adds passkeys and hardware keys

Journalists, elected officials, researchers, and political dissidents have spent years adapting their accounts to phishing-resistant authentication on consumer platforms. ChatGPT now joins that list. OpenAI has introduced Advanced Account Security, an opt-in setting that strips password-based sign-in from ChatGPT and Codex accounts and replaces it with passkeys or physical security keys. What enrollment changes Enrolled accounts use passkeys or hardware security keys for sign-in, with password login disabled. Email and SMS account recovery are removed, … More → The post ChatGPT advanced account security adds passkeys and hardware keys appeared first on Help Net Security.

Scientists built a memory chip that breaks the rules of miniaturization

A new kind of memory device may finally solve the problem of overheating and battery drain in electronics. By shrinking components to an extreme scale and redesigning their structure, researchers found a way to reduce energy loss instead of increasing it. The result is a tiny memory unit that improves as it gets smaller—something once thought impossible. This could pave the way for ultra-efficient smartphones, wearables, and AI systems.

Powerful AI finds 100+ hidden planets in NASA data including rare and extreme worlds

Astronomers have unleashed a powerful new AI tool called RAVEN to comb through data from NASA’s TESS mission—and it’s paying off in a big way. By analyzing millions of stars, the system has confirmed over 100 exoplanets, including 31 brand-new worlds, and identified thousands more promising candidates. What makes this especially exciting is the discovery of rare and extreme planets, like those that whip around their stars in less than a day and others lurking in the mysterious “Neptunian desert,” where planets are thought to be scarce.

Open-source privacy proxy masks PII before prompts reach external AI services

Enterprise developers routinely send prompts to external large language models that contain customer emails, support transcripts, and other identifying information, often without a sanitization layer between the application and the API. Dataiku has released Kiji Privacy Proxy, an open-source local gateway that detects and masks personally identifiable information before requests leave the network. The tool sits between local applications and external AI APIs such as OpenAI and Anthropic. Inbound requests pass through a machine learning … More → The post Open-source privacy proxy masks PII before prompts reach external AI services appeared first on Help Net Security.

Shadow AI risks deepen as 31% of users get no employer training

Between one-fifth and one-third of workers use AI outside the influence and governance of the IT function, according to a global survey of 6,000 full-time employees at enterprise organizations. Researchers found a widening gap between employee AI adoption and the controls organizations have in place to manage it. The Lenovo Work Reborn Research Series 2026 report documents a workforce split into two groups: employees equipped with IT-managed tools, training, and oversight, and those operating independently … More → The post Shadow AI risks deepen as 31% of users get no employer training appeared first on Help Net Security.

Identity is the control plane for distributed infrastructure

Teleport CEO Ev Kontsevoy makes the case that distributed infrastructure, across cloud, Kubernetes, databases, and servers, can’t be secured by layering more tools on top of fragmented identity systems. He argues for fewer credentials, fewer entry points, and a single identity layer that gives security and engineering teams unified visibility and control.
