If you wanted to take down a power grid or a network of drones, which part of the system should you attack? Researchers at The University of New Mexico School of Engineering posed the question in hopes of developing better network security mechanisms.... Read more

Research in the International Journal of Critical Infrastructures describes a digital-twin system that could make safety monitoring on high-rise construction sites more effective. The system could allow accident risks to be identified as they appear rather than sites simply responding to hazards after the fact.... Read more

First-of-its-kind research from Finland's Aalto University School of Business reveals the modus operandi and operating model of the pro-Russian hacking group responsible for thousands of distributed denial-of-service (DDoS) attacks against NATO and European targets. DDoS attacks can shut down public services and disrupt critical infrastructure. However, technical disruptions are not... Read more

In computer vision and robotics, ensuring that AI systems remain reliable under real-world conditions is a growing challenge. Deep neural network (DNN)-based vision systems are increasingly used in safety-critical applications such as autonomous driving, where misinterpreting a traffic sign could lead to unsafe decisions. Everyday wear and tear can subtly... Read more

By combining two complementary clues—camera geometry and visual appearance—researchers at the Institute of Science Tokyo, Japan, developed a new approach for preserving identities across multiple cameras. The method uses epipolar geometry to identify spatially consistent candidate matches and appearance similarity to distinguish among possible identities. The approach can be integrated... Read more

U.S. law enforcement on Tuesday announced the seizure of internet domains allegedly used by Chinese hackers to target government agencies and critical infrastructure.... Read more

Shine a light, and the real can be distinguished from the fake. KAIST researchers have developed a security technology that uses unique artificial fingerprints created by the random assembly of nanoparticles. Although extremely difficult to replicate, these fingerprints can be conveniently authenticated using only a smartphone flashlight and a laser... Read more

Safety protections built into some of the world's most widely used artificial intelligence (AI) models can be stripped away with alarming ease, according to a new international study.... Read more

Consumer detectors sold to help people find hidden surveillance devices are often too difficult for typical users to interpret, potentially giving a false sense of security to those most at risk such as domestic abuse survivors, finds a new study led by UCL researchers.... Read more

Experts have shown that the most powerful security defenses in Windows 11 can be dismantled by an attacker who never touches the target computer.... Read more

"Pics or it didn't happen" was something people used to say online when they wanted to verify a claim. Technology has changed this.... Read more

The COVID-19 pandemic changed the way many people approached their work across the globe. For Carnegie Mellon University Africa's Jema Ndibwile, it changed the way he viewed a completely different type of virus: a computer virus.... Read more

College administrators read an adjunct professor's comments to students on personal essays. Managers told a pharmacist to spend less time with patients after tracking the number and length of her appointments. Scanners on a warehouse conveyor belt monitored the pace of workers to ensure they inspected hundreds of items per... Read more

Australia's national response to scams has strengthened in recent years through government-led anti-scam measures. Yet losses remain above $2 billion, and scams continue to have a significant and devastating impact on individuals, particularly those in vulnerable communities. In a new white paper, RMIT professor Mathews Nkhoma has identified the critical... Read more

Counterfeit and out-of-spec components are entering U.S. defense supply chains through thousands of small and midsized suppliers that make up the lower tiers of the industrial base. Researchers at the Georgia Tech Manufacturing Institute (GTMI) say the fix isn't just better parts, but better proof: verified digital records, secured against... Read more
