Researchers built a continuous authentication system called AccLock that identifies a wearer by the tiny vibrations a heartbeat makes inside the ear canal. The signal comes from an accelerometer of the kind already sitting inside many wireless earbuds,…
Household refrigerators are built to last more than a decade. The software, cloud services, and mobile apps that control them are not. A new analysis from Erik Buchmann at Leipzig University maps what happens when those two timelines collide, and the f…
A new rowhammer attack gives complete control of NVIDIA CPUs.
On Thursday, two research teams, working independently of each other, demonstrated attacks against two cards from Nvidia’s Ampere generation that take GPU rowhammering into new—and potentially much more consequential—territory: GDDR bitflips that give adversaries full control of CPU memory, resulting in full system compromise of the host machine. For the attack to work, IOMMU memory management must be disabled, as is the default in BIOS settings.
“Our work shows that Rowhammer, which is well-studied on CPUs, is a serious threat on GPUs as well,” said Andrew Kwong, co-author of one of the papers. “…
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 …
Global spending on IT is expected to reach $6.31 trillion in 2026, according to the latest quarterly forecast from Gartner, marking a 13.5% increase from the previous year. The forecast shows that growth is spread across all major segments, though not …
Racks of phones and 4G modems, connected to carrier networks and rented out as commercial mobile proxy services, are operating across at least 94 locations in 17 countries. An investigation by infrastructure intelligence firm Infrawatch traced a large …

This is for new routers; you don’t have to throw away your existing ones:
The Executive Branch determination noted that foreign-produced routers (1) introduce “a supply chain vulnerability that could disrupt the U.S. economy, critical infrastructure, and national defense” and (2) pose “a severe cybersecurity risk that could be leveraged to immediately and severely disrupt U.S. critical infrastructure and directly harm U.S. persons.”

Any new router made outside the US will now need to be approved by the FCC before it can be imported, marketed, or sold in the country…
Drone detection in cities is expensive. Dedicated radar installations are cost-prohibitive at scale, cameras have limited range and stop working well at night, and LiDAR systems have the same cost problem as radar. A group of researchers at the Univers…
Intel engineers have published a centralized repository of data center performance knowledge on GitHub, giving practitioners direct access to tuning guides, configuration recommendations, and optimization recipes that previously required hunting across…
