More than 46 million signals of potential cyber attacks are spotted by cyber security experts every day around the world, according to new data from BT. The telecoms giant said more than 530 signals of potential attack were logged per second. It said hackers were relentlessly scanning devices connected to the internet looking for weaknesses by using automation and machine learning to identify vulnerabilities in cyber defences. The BT data showed that over the last 12 months the IT, defence, banking and insurance sectors were the most targeted by cyber criminals, followed by the retail, hospitality and education industries. According to the figures, around 785,000 cyber attacks also targeted charities over the last year. The company warned that these trends should be of greater concern when over half of businesses (61%) told a BT survey in May that they find keeping up with cyber security measures increasingly difficult. BT has published the figures to mark Cyber Security Awareness Month, and has also launched a new podcast series called True Cybercrime Stories by BT, which details the true stories behind some of the world’s most notable cyber attacks. Tris Morgan, manager director for security at BT, said: “The volume of cyber threats in the UK is rising at an alarming rate, so it’s really concerning that so many businesses and public services are leaving themselves open to attack. “The fabric of the modern business has changed, and there’s now more connected tech for hackers to exploit, more valuable data to target and a bigger prize at stake if they make it through. “With more than a million business customers, BT is the first line of cyber defence for organisations across the world – and we’re proud of our long heritage of protecting people, businesses and critical national infrastructure. That’s why we’re launching the True Cybercrime Stories podcast: to shine a light on the shocking impact this crime epidemic can have, raise awareness of the risks and encourage everyone to think about what they could be doing to protect our businesses and essential services.” Read More AI being used to create child abuse imagery, watchdog warns ChatGPT and other chatbots ‘can be tricked into making code for cyber attacks’ Tinder adds Matchmaker feature to let friends recommend potential dates

Scientists have finally found a “demon” subatomic particle that was predicted to exist nearly seven decades ago and speculated to play an important role in the behaviours of a range of metals and alloys, including superconductors. Physcist David Pines in 1956 theorised that electrons, which normally have a mass and negative electric charge, can under some conditions combine to form a composite “demon” particle that is massless, neutral and does not interact with light. These theorised interesting properties, however, made these particles elude detection – until now. After a nearly 70-year search for these subatomic entities, researchers, including those from the University of Illinois Urbana-Champaign, have finally found signatures of Dr Pines’ “demon” particles in the metal strontium ruthenate. “Demons have been theoretically conjectured for a long time, but experimentalists never studied them. In fact, we weren’t even looking for it. But it turned out we were doing exactly the right thing, and we found it,” study co-author Peter Abbamonte said. Electrons – which are distributed in different energy bands within atoms – are known to lose their individuality in solids with electric interactions making the particles combine to form collective units. With some threshold energy, studies have also shown electrons can form composite particles called plasmons with a new charge and mass. However, the mass is so large that these plasmon particles cannot form with the kind of energies available at room temperature. Revelations on room-temperature semiconductors are considered to be one of the “holy grails” of physics. But Dr Pines theorised that if a solid has electrons in more than one energy band, as many metals do, their respective plasmons may combine in an out-of-phase pattern to form a new plasmon that is massless and neutral – a demon. Since these special particles are massless, he argued they can form with any energy and may exist at all temperatures – leading to speculation that the demons have important effects on the behaviour of some metals with multiple energy bands. “The vast majority of experiments are done with light and measure optical properties, but being electrically neutral means that demons don’t interact with light,” Dr Abbamonte explained. So a completely new experiment was needed to detect them. In the research, scientists were studying the compound strontium ruthenate as it is similar to high-temperature superconductors – a special kind of material where electrical resistance vanishes. For a survey of the metal’s electronic properties, they synthesised high-quality samples of the metal. They then applied a technique to study the metal that uses energy from electrons shot into the metal to directly observe the metal’s features, including plasmons that form. During their observation of the electron interactions, scientists found something unusual – an electronic mode with no mass. “At first, we had no idea what it was. Demons are not in the mainstream. The possibility came up early on, and we basically laughed it off. But, as we started ruling things out, we started to suspect that we had really found the demon,” Ali Husain, another author of the study, said. Researchers then sought to calculate how electrons are distributed across bands inside strontium ruthenate. Predictions by Dr Pines indicate there are specific conditions when “demons” are likely to form, and it remained unknown whether strontium ruthenate would have the particle. “We had to perform a microscopic calculation to clarify what was going on. When we did this, we found a particle consisting of two electron bands oscillating out-of-phase with nearly equal magnitude, just like Pines described,” found Edwin Huang, another author of the study. “Our study confirms a 67-year-old prediction and indicates that demons may be a pervasive feature of multiband metals,” scientists wrote in the study.
