Meta AI agent’s instruction causes large sensitive data leak to employees

about 16 hours ago

An AI agent instructed an engineer to take actions that exposed a large amount of Meta’s sensitive data to some of its employees, in the latest example of AI causing upheaval in a large tech company.The leak, which Meta confirmed, happened when an employee asked for guidance on an engineering problem on an internal forum.An AI agent responded with a solution, which the employee implemented – causing a large amount of sensitive user and company data to be exposed to its engineers for two hours.“No user data was mishandled,” a Meta spokesperson said, and they emphasised that a human could also give erroneous advice.The incident, first reported by The Information, triggered a major internal security alert inside Meta, which the company has said is an indication of how seriously it takes data protection.

This breach is one of several recent high-profile incidents caused by the increasing use of AI agents within US tech companies,Last month, a report from the Financial Times said Amazon experienced at least two outages related to the deployment of its internal AI tools,More than half a dozen Amazon employees later spoke to the Guardian about the company’s haphazard push to integrate AI into all elements of their work, leading, they said, to glaring errors, sloppy code and reduced productivity,The technology that underlies all these incidents, agentic AI, has evolved rapidly over the past months,In December, developments in Anthropic’s AI coding tool, Claude Code, triggered widespread hubbub over its ability to autonomously book theatre tickets, manage personal finance, and even grow plants.

Soon after was the advent of OpenClaw, a viral AI personal assistant that ran on top of agents such as ClaudeCode but could operate entirely autonomously – trading away millions of dollars in cryptocurrency, for example, or mass-deleting users emails – leading to heady talk about the advent of AGI, or artificial general intelligence, a catch-all term for AI that is capable of replacing humans for a wide number of tasks.In the weeks that followed, stock markets have wobbled over fears that AI agents will gut software businesses, reshape the economy and replace human workers.Tarek Nseir, a co-founder of a consulting company focused on how businesses use AI, said these incidents showed that Meta and Amazon were in “experimental phases” of deploying agentic AI.“They’re not really kind of standing back from these things and actually really taking an appropriate risk assessment.If you put a junior intern on this stuff, you would never give that junior intern access to all of your critical severity one HR data,” he said.

“The vulnerability would have been very, very obvious to Meta in retrospect, if not in the moment,And what I can say and will say is this is Meta experimenting at scale,It’s Meta being bold,”Jamieson O’Reilly, a security specialist who focuses on building offensive AI, said AI agents introduced a certain kind of error that humans did not – and this may explain the incident at Meta,A human knows the “context” of a task – the implicit knowledge that one should not, for example, set the sofa on fire in order to heat the room, or delete a little-used but crucial file, or take an action that would expose user data downstream.

For AI agents, this is more complicated.They have “context windows” – a sort of working memory – in which they carry instructions, but these lapse, leading to error.“A human engineer who has worked somewhere for two years walks around with an accumulated sense of what matters, what breaks at 2am, what the cost of downtime is, which systems touch customers.That context lives in them, in their long-term memory, even if it’s not front of mind,” O’Reilly said.“The agent, on the other hand, has none of that unless you explicitly put it in the prompt, and even then it starts to fade unless it is in the training data.

”Nseir said: “Inevitably there will be more mistakes.”

House of Lords has ‘signed its own death warrant’ by stalling assisted dying bill, says MP

The House of Lords “signed its own death warrant” over its stalling of the UK assisted dying bill, the MP Kim Leadbeater said as she joined more than a dozen terminally ill and bereaved people in protest outside parliament.Marking the second anniversary of the death at Dignitas of the prominent assisted dying campaigner Paola Marra, Leadbeater, whose private member’s bill for England and Wales looks set to run out of time, said many MPs, who had already voted by a majority to pass the bill, were “angry and upset” by the addition of about 1,200 amendments in the Lords, which will probably result in the bill falling without a vote.The protest, organised by the campaign group Dignity in Dying, came as the number of UK residents who had an assisted death at Dignitas rose to its second-highest level in two decades. Forty-three people travelled to Switzerland in 2025, up from 37 the previous year, and second only to 47 people in 2016, figures show.Leadbeater said of the teminally ill adults (end of life) bill: “MPs took this decision having entered into this debate in a really serious, considered manner

The Kent meningitis outbreak: what is happening and why?

The deadly outbreak of meningitis in Kent has fuelled concerns about how far the disease will spread and seen the return of people wearing masks and queueing for vaccines. The scenes are reminiscent of the Covid crisis, but meningitis is very different. Here we look at how the outbreak has unfolded.Meningitis is a potentially lethal but uncommon disease caused by viruses and bacteria that trigger inflammation of the meninges, the protective linings that cover the brain. The Kent outbreak is driven by meningococcal bacteria which are found in the nose and throat of about 10% of the population

Tessa Richards obituary

My friend Tessa Richards, who has died of cancer aged 75, was a doctor and medical editor who campaigned indomitably for patients to be partners equal with doctors in healthcare. In addition, she transformed the relationship that the BMJ (formerly the British Medical Journal), where she worked for 40 years, had with patients.When Tessa graduated in medicine from Guy’s hospital medical school in London in 1973, doctors dominated patients, and did what they thought best for them. There was no culture of patients being equal partners, and doctors discussing options with them. As Tessa wrote in 1990: “Even the briefest spell on the other side of the desk or in a hospital bed gives blinding insight into patients’ vulnerability and of their need to be listened to, treated with respect, and given full, unhurried, jargon-free explanations

George Nicholson obituary

Borough Market in London is today a thriving market and popular place to eat – George Nicholson, who has died aged 79, was chair of its board of trustees for 10 years until 2006, and, as such, contributed much to that success. He loved the place; he and I ate there together, as friends, on his last birthday.George was proud of being a Londoner and his sense of civic pride and commitment to London continued all his life. In 1981 he was elected as the Labour member for Bermondsey of the Greater London council. He became chair of the GLC planning committee, advocating for Thames beaches, social housing, the best of urbanism and celebration of the possible
