British computer scientist denies he is bitcoin developer Satoshi Nakamoto

A British computer scientist has insisted he is not the elusive developer of bitcoin, after a report claimed to unmask him as its creator.A story in the New York Times details a years-long effort to unmask Satoshi Nakamoto, the mysterious author of the bitcoin white paper which laid the theoretical foundations for modern digital currencies.It names Adam Back, a London-born computer scientist and entrepreneur. In a thread on X, Back promptly denied being the mysterious – and presumably ultra-wealthy – technologist.“I also don’t know who satoshi is, and i think it is good for bitcoin that this is the case, as it helps bitcoin be viewed [as] a new asset class, the mathematically scarce digital commodity,” he wrote

Britons warned about Russian hackers targeting internet routers for espionage

Russian hackers are exploiting commonly sold internet routers to harvest information for espionage purposes, the UK’s cybersecurity agency has said.The hack could allow attackers to obtain users’ credentials, redirect them to fake sites, and potentially access other devices on their home network such as phones and PCs, said Alan Woodward, a professor at the University of Surrey.The National Cyber Security Centre said on Tuesday the operations were “believed to be opportunistic in nature, with the actor targeting a wide pool of victims and then likely filtering down for users of potential intelligence value at each stage of the exploitation chain”.It follows a common pattern of cyber-actors targeting edge devices – hardware such as internet routers or internet-connected security cameras – that act as a bridge between users and the cloud.Woodward said: “It’s not the first time that warnings have come out about routers

The life-changing magic of wearing smartglasses | Letters

I read with sympathy the concerns of Elle Hunt in relation to privacy issues around Meta smartglasses (I wore Meta’s smartglasses for a month – and it left me feeling like a creep, 1 April). Clearly there needs to be ongoing development of technology and protocols that protect the public from ill-intentioned users. As the chief executive of a charity supporting people with a visual impairment, however, I would like to emphasise the point touched upon in your article: how transformative this technology is already proving for blind people.We are seeing significant numbers of our visually impaired staff and clients using Meta glasses in conjunction with their mobile phones to improve their ability to perform ordinary functions that most of us take for granted. A visual impairment can be disempowering and isolating

An AI company with an arsenal of spacecraft: what exactly is SpaceX?

Hello, and welcome to TechScape. I’m your host, Blake Montgomery, US tech editor at the Guardian, writing to you as I listen to George Handel’s Messiah for Easter.SpaceX filed confidentially for an initial public offering on the US stock market last week at a reportedly astronomical valuation. My colleague Nick Robins-Early reports:Elon Musk’s company, which has become a dominant power in both space travel and satellite communications, could seek a valuation upwards of $1.75tn

Porn, dog poo and social media snaps: the ‘taskers’ scraping the internet for AI firm part-owned by Meta

Tens of thousands of people have been paid by a company part-owned by Meta to train AI by combing Instagram accounts, harvesting copyrighted work and transcribing pornographic soundtracks, the Guardian can reveal.Scale AI, 49%-controlled by Mark Zuckerberg’s social media empire, has recruited experts across fields such as medicine, physics and economics – putatively to refine top-level artificial intelligence systems through a platform called Outlier. “Become the expert that AI learns from,” it says on its site, advertising flexible work for people with strong credentials.However, workers for the platform said they have become involved in scraping an array of other people’s personal data – in what they described as a morally uncomfortable exercise that diverged significantly from refining high-level systems.Outlier is managed by Scale AI, which has contracts with the Pentagon and US defense companies
