FBI: Reported cryptocurrency losses reached $5.6 billion in 2023

Posted by in categories: cryptocurrencies, government, internet

The FBI says that 2023 was a record year for cryptocurrency fraud, with total losses exceeding $5.6 billion, based on nearly 70,000 reports received through the Internet Crime Complaint Center (IC3).

This marks a 45% increase in losses compared to the previous year, driven primarily by investment fraud, which accounted for 71% of the total cryptocurrency losses. Other types of fraud contributing to the statistics include tech support scams, call center fraud, and government impersonation.

The vast majority of the reported losses ($4.8 billion) were incurred by U.S. citizens, followed by Cayman Islands ($196M), Mexico ($127M), Canada ($72M), the UK ($59M), India ($44M), and Australia ($25M).

New PIXHELL acoustic attack leaks secrets from LCD screen noise

Posted by in categories: cybercrime/malcode, mobile phones

A novel acoustic attack named ‘PIXHELL’ can leak secrets from air-gapped and audio-gapped systems, and without requiring speakers, through the LCD monitors they connect to.

In a PIXHELL attack, malware modulates the pixel patterns on LCD screens to induce noise in the frequency range of 0–22 kHz, carrying encoded signals within those acoustic waves that can be captured by nearby devices such as smartphones.

The researchers’ tests showed that data exfiltration is possible at a maximum distance of 2 meters (6.5 ft), achieving a data rate of 20 bits per second (bps).

A Completely New Structure of Light Has Been Created: The Chiral Vortex

Posted by in category: space

“Traditional measures of chirality have struggled to identify the concentration of right-and left-handed molecules in samples containing almost equal amounts of both,” says physicist Nicola Mayer, from the Max Born Institute.

“With our new method, a tiny excess in the concentration of either mirror twin can be detected, possibly enough to make a life-changing difference.”

We’re not sure how chirality first emerged, but it may have originated from deep space, before going on to play a profound role in so many different aspects of life on Earth. Having instruments that can better detect chiral molecules would be a major step forward.

OpenAI releases reasoning AI with eye on safety, accuracy

Posted by in categories: mathematics, robotics/AI

ChatGPT creator OpenAI on Thursday released a new series of artificial intelligence models designed to spend more time thinking—in hopes that generative AI chatbots provide more accurate and beneficial responses.

The new models, known as OpenAI o1-Preview, are designed to tackle and solve more challenging problems in science, coding and mathematics, something that earlier models have been criticized for failing to provide consistently.

Unlike their predecessors, these models have been trained to refine their thinking processes, try different methods and recognize mistakes, before they deploy a final answer.

Fluorescent nanomaterial could transform how we visualize fingerprints

Posted by in categories: chemistry, nanotechnology, particle physics

Latent fingerprints require physicochemical development techniques to enhance their visibility and make them interpretable for forensic purposes. Traditional methods for developing fingerprints include optical, physical, and chemical processes that involve interaction between the developing agent (often a colored or fluorescent reagent) and the fingerprint residue. These methods have limitations in recovering high-quality results in certain conditions.

Recently, new methods using , spectroscopy, electrochemistry, and nanoparticles have improved the development of latent fingerprints. These techniques offer better contrast, sensitivity, and selectivity, with low toxicity. The ability to adjust nanomaterial properties further enhances the detection of both fresh and aged fingerprints.

Mesoporous silica nanoparticles (MSNs) have attracted significant interest since the discovery of the M41S family of molecular sieves, which encompasses MCM-41, MCM-48, and SBA-15. These nanoparticles are characterized by their controlled particle size, porosity, high specific surface area, chemical stability, and ease of surface functionalization.
