Smart toasters may be used to spy on people
As tech firms ditch security updates for old devices that are connected to the web via Wi-Fi, it gives people the perfect opportunity to hack into the products.
It comes as cyber attackers launched a "zombie army" of internet-connected devices in 2016, which resulted in them shutting down large parts of the web.
Alan Woodward, a cybersecurity professor at the University of Surrey, added that non-protected devices act as a "stepping stone" for hackers.
He is quoted by The Times as saying: 'In some ways, it might not matter that your toaster doesn't get updated.
'But actually if it's on your network and somebody discovers a vulnerability, that vulnerability is never going to be fixed.
"If it remains connected and it's just kind of ignored, then it can be a stepping stone."
Andrew Laughlin, from consumer choice brand Which?, told the publication: "This is a pattern that we see time and again as companies drop support for their smart products, sometimes after as little as two years."

Fears Australia faces ‘missed opportunity'
Australia could miss out on its next great invention plus significant economic benefits, with one prominent business leader calling for an increase in research and development spending so we no longer lag behind other developed countries. Business Council of Australia chief executive Bran Black says the Albanese government should help boost public and private spending into research and development from 1.7 per cent of GDP to 3 per cent. As it stands, Australia is dragging behind the other OECD countries which on average invest 2.7 per cent of GDP into funding and developing innovating ideas. Australia was also significantly behind the United States and South Korea which invest 3.59 per cent and 5.21 per cent respectively. As a result, the country was missing out on the economic returns, with Mr Black pointing to analysis from the CSIRO which found that every dollar invested in R&D offered a $3 return to GDP. 'They're doing that because they see that the economic return, the dividend to their economy associated with these types of investment makes it worthwhile,' he said. More and better innovation also had the power to make 'life better' too, said Mr Black, pointing to world-leading Australian inventions such as the cochlear implant, Google Maps, pacemakers and even Wi-Fi. Business Council of Australia chief executive Bran Black is calling for more investment in R&D. NewsWire / Martin Ollman Credit: News Corp Australia 'If we talk about these types of inventions – being able to hear, being able to see your child, being able to navigate your way through cities and towns with confidence – that is genuinely a reflection of how our society has changed as a consequence of good old Australian R&D,' he said. 'R&D when done right changes the way we live, every single day.' While sectors such as agriculture, health, renewables and the resources sector were areas where Australia had 'existing advantages,' he said there was also 'scope for opportunity' in more left field areas like quantum computing. Figures released by the Department of Industry, Science and Resources tip Australia's technology sector is set to contribute $244bn a year to the economy by 2031, a rapid increase from the current $167bn. Increasing Australia's quantum capabilities is set to amplify the growth of the sector. 'Who would have thought that Australia would be at the absolute forefront of global research with respect to this cutting edge technology, and yet we are,' he said. Speaking to the importance of R&D, Mr Black said analysis from the CSIRO found Australia stood to receive a $3 boost to GDP for every dollar invested in R&D. NewsWire/ Nicholas Eagar Credit: NewsWire The push for a higher spend on R&D comes as Labor seeks to unite union and business leaders for a productivity roundtable which will be held at Parliament House in August. Mr Black said boosting Australian innovation was a key way to expose Australia to new market, create new jobs and develop emerging industries. In addition for a 5 per cent target on increased funding from the public and private sector, the BCA is also calling for a better tax incentives to encourage domestic and international to invest in Australian projects, plus a publicly accessible National Researcher Directory to help connect industry with research expertise. 'Ultimately what that means is that R&D is an excellent way of driving productivity (and) productivity is the main determinant for how we can deliver real wages growth across our economy,' he said. Labor is undertaking a strategic review into its R&D processes, with the government set to receive the recommendations by the end of the year. Former industry and science minister Ed Husic also acknowledged in October last year that R&D funding in Australia was at a 'sorry state,' and said the government was 'very focused on fixing up our languishing national R&D spend'.

This ring wants to help you live longer. I gave it a try
From smartwatches to connected scales and even Wi-Fi beds, it's a well-established idea that access to information about how our bodies are running can help us meet our wellness goals, get an early warning on potential issues and encourage healthy habits. And a new gadget has emerged recently that promises 24/7 tracking in the most subtle way possible; disguised as a ring. Smart rings from Samsung and Oura have shown what's possible, and the new Ultrahuman Ring Air is an even lighter and less conspicuous option. At $600 (and no subscription necessary), it's a plain and extremely light ring in black, gold, silver or grey titanium, with a comfy hypoallergenic epoxy on the inside that lets you peer in at the hardware for measuring heart rate, skin temperature, movement, blood oxygen and more. And, of course, it connects to its own app on your iPhone or Android. Physically, it's an undeniably masculine ring, but it does look like regular dumb jewellery at a glance. Mine has picked up a lot of scratches and marks on the coating over a few weeks of wear, so I'm not sure what it would look like in a year. It just feels like wearing a ring, and most of the time I forget it's there. The ring takes heart rate readings periodically, counts steps and detects workouts for finer tracking. When you sleep or nap, it calculates stages and monitors movement and timing. And all the data goes to the main platform to be crunched into insights about stress, recovery, alertness and more. Ultrahuman is a platform based in India that focuses on longevity through data tracking. In addition to the ring, it sells a biosensor for continuous glucose monitoring, so you can see the effect of food on your metabolism, and the software is big on keeping biomarkers within certain zones. While collecting data on our bodies can be good, it's also known that becoming too attached to the numbers can be decidedly unhealthy, and it's easy to be reminded of this when glancing at all the goals and dashboards in the Ultrahuman app. Whether the platform can ultimately help people live longer is a bit beyond the scope of this review. But based purely on my experience with this ring and its app, even if I could somehow be assured that following every one of the suggestions would net me a few extra days on Earth, I'm not certain it would be worth it. By default, Ultrahuman bombards me with reminders to stick to my 'caffeine permissible window', which apparently doesn't start until two hours after I wake up; and warnings to limit light exposure by 7pm. I get vague informational updates about sleep debt and stress rhythm, reminders to stretch my limbs and walk around, and prods about infinitesimal changes in my heart rate variability. If you dive into the data in the app, you can get lost in a sea of minima zones, phase advance goals (it's tracking my progress towards waking my body up earlier, but I already get up at 6.30?), sympathetic activation and hormone health.
