Cybercriminals shift tactics to pressure more victims into paying ransoms

Ransomware didn’t just grow in the US in 2023, it evolved, with the frequency of ransomware claims jumping 64% year-over-year, according to At-Bay. This was primarily driven by an explosion in “indirect” ransomware incidents which increased by more than 415% in 2023 than in 2022. Standing out among the biggest loss drivers were remote access tools, which accounted for 58% of ransomware attacks. Double leverage attacks – those using both data encryption and exfiltration – … More → The post Cybercriminals shift tactics to pressure more victims into paying ransoms appeared first on Help Net Security.

Consumers continue to overestimate their ability to spot deepfakes

The Jumio 2024 Online Identity Study reveals significant consumer concerns about the risks posed by generative AI and deepfakes, including the potential for increased cybercrime and identity fraud. The study examined the views of more than 8,000 adult consumers, split evenly across the United Kingdom, United States, Singapore and Mexico. The results suggest nearly 72% worry on a day-to-day basis about being fooled by a deepfake into handing over sensitive information or money. Only 15% … More → The post Consumers continue to overestimate their ability to spot deepfakes appeared first on Help Net Security.

Tech can’t replace human coaches in obesity treatment

Technology alone can’t replace the human touch to produce meaningful weight loss in obesity treatment, reports a new study. Giving people technology alone for the initial phase of obesity treatment produces unacceptably worse weight loss than giving them treatment that combines technology with a human coach. The need for low cost but effective obesity treatments delivered by technology has become urgent as the ongoing obesity epidemic exacerbates burgeoning health care costs. Researchers are studying why how to make tech approximate human coaches.

Scientists create an ‘optical conveyor belt’ for quasiparticles

Using interference between two lasers, a research group has created an ‘optical conveyor belt’ that can move polaritons — a type of light-matter hybrid particle — in semiconductor-based microcavities. This work could lead to the development of new devices with applications in areas such as quantum metrology and quantum information.

Learning the imperfections: New approach to using neural networks for low-power digital pre-distortion (DPD) in mmWave systems

Engineers have demonstrated a simple computational approach for improving the linearization of power amplifiers (PA), such as those used in mmWave systems and other telecommunication systems. The proposed technique involves training small neural networks to directly estimate the coefficients of a polynomial for digital pre-distortion (DPD) based on their frequency response during calibration sweeps.
