MIT scientists finally reveal the hidden structure of a mysterious high-tech material

For decades, relaxor ferroelectrics have powered everything from medical ultrasounds to sonar systems, yet their inner atomic structure remained a mystery—until now. Researchers have finally mapped their three-dimensional structure in unprecedented detail, uncovering hidden patterns in how electric charges are arranged at the nanoscale. The breakthrough not only challenges long-standing assumptions about how these materials behave but also allows scientists to refine the models used to design them.

Pipelock: Open-source AI agent firewall

AI coding agents run with shell access, environment variables containing API keys, and unrestricted internet connectivity, creating a single point of failure where one compromised tool call can leak credentials to an attacker-controlled domain. Pipelock, an open-source security harness developed by Joshua Waldrep under the PipeLab project, addresses this exposure by inserting an enforcement layer between agents and the network. Version 2.3.0 shipped with class-preserving request redaction and generic SSE streaming response scanning. Architecture and … More → The post Pipelock: Open-source AI agent firewall appeared first on Help Net Security.

Spotting third-party cyber risk before attackers do

In this Help Net Security video, Jeffrey Wheatman, SVP and Cyber Strategist at Black Kite, discusses how organizations can identify and manage third-party cyber exposures before attackers exploit them. He argues that businesses should move beyond a data-loss mindset toward one centered on resilience, meaning keeping operations running when vendors or partners get hit. Wheatman walks through practical steps: engaging business stakeholders early, scoping which third parties are business critical, retiring outdated questionnaire-based assessments, and … More → The post Spotting third-party cyber risk before attackers do appeared first on Help Net Security.
