New light trap design supercharges atom-thin semiconductors

Scientists have found a clever way to supercharge ultra-thin semiconductors by reshaping the space beneath them rather than altering the material itself. By placing a single-atom-thick layer of tungsten disulfide over tiny air cavities carved into a crystal, they created miniature “light traps” that dramatically boost brightness and optical effects—up to 20 times stronger emission and 25 times stronger nonlinear signals. These hollow structures, called Mie voids, concentrate light exactly where the material sits, overcoming a major limitation of atomically thin devices.

Measuring security performance in real-time, not once a quarter

Most organizations have invested heavily in security products over the past decade. The assumption embedded in that spending is that more tools equal better protection. Tim Nan, CEO of digiDations, says that assumption is the most persistent misconception he encounters when working with security leaders across industries. “Adversaries don’t operate on averages,” Nan says. “They only need one path that works. The issue isn’t whether your defenses work most of the time. It’s whether they … More → The post Measuring security performance in real-time, not once a quarter appeared first on Help Net Security.

Attackers are handing off access in 22 seconds, Mandiant finds

Exploits remain the leading entry point for attackers for the sixth consecutive year, according to Mandiant’s M-Trends 2026 report, which draws on more than 500,000 hours of incident response work conducted in 2025. The data shows attackers speeding up their internal hand-offs, shifting away from email phishing, and targeting backup and virtualization infrastructure with greater precision. Initial infection vector 2025 (Source: Mandiant) Voice phishing surges as email phishing continues to decline Voice phishing climbed to … More → The post Attackers are handing off access in 22 seconds, Mandiant finds appeared first on Help Net Security.
