Hostile SIMs, Private AI Tools and Earlier Storm Warnings
This briefing examines hostile SIM commands affecting connected devices, a private AI workbench linked to North Korean hackers, a US dispute over research-grant oversight, early findings from blood-filtering treatment, improved solar-storm tracking, and an AI model offering more useful cyclone forecast lead time.

Hostile SIMs Exposed Commands on Connected Devices
Security researchers tested phones and cellular Internet of Things modules with a hostile SIM and found that some accepted modem-control commands. Demonstrated effects ranged from losing connectivity to code execution, depending on the device. The attack requires control of a physical SIM, eSIM, or related management channel, so an ordinary website cannot launch it. Several affected vendors have already issued updates or hardened configurations.

North Korea-Linked Hackers Built a Private AI Workbench
Investigators found local language models, document-search software, agent-development tools, and AI-assisted coding software on infrastructure linked to the Kimsuky hacking group. Running models privately could help operators analyse stolen files and refine phishing while keeping sensitive data away from cloud providers. However, the evidence comes primarily from one security company and does not demonstrate an autonomous cyberattack or measure whether AI improved the group’s success.

US Senate Moves to Delay a Contested Federal Grants Rule
The US Senate approved a short-term funding bill containing language that would pause a proposed federal grants rule through December 11, 2026. The rule would give senior political appointees more authority over grant awards and terminations, including funding that supports scientific research. The Senate vote does not make the pause law: the House passed different legislation, and both chambers must agree before a final measure can reach the president.

A Cholesterol Treatment Also Removed Some Forever Chemicals
Doctors in Germany found that a blood-filtering treatment used for severe cholesterol disorders also lowered several PFAS forever chemicals, with those substances detected in filtered material. Researchers also measured plastic particles in patients’ blood, though those results were inconsistent and sometimes rose after treatment. This was a small exploratory study without a control group, and it does not show that the procedure removes pollution stored in organs or improves health.

NASA Mission Narrows One Solar Storm Arrival Estimate
NASA’s PUNCH mission continuously tracked a coronal mass ejection from the Sun toward Earth and produced an arrival estimate that was accurate to within half an hour. Continuous imaging could eventually give power-grid and satellite operators more useful preparation time than forecasts based mainly on a storm’s early journey. The result covers one retrospective case presented at a scientific meeting, remains under peer review, and is not yet an operational forecasting system.

AI Cyclone Model Gains Useful Forecasting Time
WeatherNext Cyclones predicted tropical-storm tracks, intensity, and wind extent in one ensemble system, with its three-day forecasts matching the accuracy leading systems reached at two days on average. The Nature study evaluated storms from 2023 through 2025 and included live operation during the 2025 Atlantic hurricane season. The advantage varies across storms and does not replace observations, local hazard models, physics-based forecasts, or expert meteorologists.
