Kimsuky Exploits BlueKeep RDP Vulnerability to Breach Systems in South Korea and Japan

Cybersecurity researchers have flagged a new malicious campaign related to the North Korean state-sponsored threat actor known as Kimsuky that exploits a now-patched vulnerability impacting Microsoft Remote Desktop Services to gain initial access.

The activity has been named Larva-24005 by the AhnLab Security Intelligence Center (ASEC).

“In some systems, initial access was gained through exploiting the RDP vulnerability (BlueKeep, CVE-2019–0708),” the South Korean cybersecurity company said. “While an RDP vulnerability scanner was found in the compromised system, there is no evidence of its actual use.”

Scientists Discover New “Hall Effect” That Could Revolutionize Electronics

Scientists discovered a new Hall effect driven by spin currents in noncollinear antiferromagnets, offering a path to more efficient and resilient spintronic devices.

A research team led by Colorado State University graduate student Luke Wernert and Associate Professor Hua Chen has identified a previously unknown type of Hall effect that could lead to more energy-efficient electronic devices.

Their study, published in Physical Review Letters.

A cool fix for hot chips: Advanced thermal management technology for electronic devices

The exponential miniaturization of electronic chips over time, described by Moore’s law, has played a key role in our digital age. However, the operating power of small electronic devices is significantly limited by the lack of advanced cooling technologies available.

Aiming to tackle this problem, a study published in Cell Reports Physical Science, led by researchers from the Institute of Industrial Science, The University of Tokyo, describes a significant increase in performance for the cooling of electronic chips.

The most promising modern methods for chip cooling involve using microchannels embedded directly into the chip itself. These channels allow water to flow through, efficiently absorbing and transferring heat away from the source.

Firefly light gives rise to sensor that detects cellular alterations

The gene encoding an enzyme from a firefly, discovered at the Sorocaba campus of the Federal University of São Carlos (UFSCar) in Brazil, has given rise to a biosensor capable of detecting pH changes in mammalian cells—which could be useful, for example, in studying diseases and assessing the toxicity of a drug candidate.

The luciferase from the species Amydetes vivianii changes color from bluish-green to yellow and red as acidity decreases in fibroblasts, the most common cell type in connective tissue. It does so with great intensity and stability, something that had not been achieved with other luciferases tested by the research group.

The work is published in the journal Biosensors.

Twisted crystals open door to smaller, more powerful sensors for optical devices

Twisted moiré photonic crystals—an advanced type of optical metamaterial—have shown enormous potential in the race to engineer smaller, more capable and more powerful optical systems. How do they work?

Imagine you have two pieces of fabric with regular patterns, like stripes or checkers. When you lay the two pieces of fabric directly on top of each other, you can see each pattern clearly. But if you slightly shift one piece of fabric or twist it, new patterns that weren’t in either of the original fabrics emerge.

In twisted moiré photonic crystals, how the layers twist and overlap can change how the material interacts with light. By changing the twist angle and the spacing between layers, these materials can be fine-tuned to control and manipulate different aspects of light simultaneously—meaning the multiple optical components typically needed to simultaneously measure light’s phase, polarization, and wavelength could be replaced with one device.
