Separate actions also take place outside fence and across Europe in backlash against impact of AI boom

Activists have stormed the site of a Microsoft datacentre being built in Amsterdam, as the backlash to the social and environmental harms of the AI boom spreads across Europe.

Protesters from Geef Tegengas, a Dutch direct action group, clashed with police while breaking into a construction site at Westpoort, Amsterdam, where some members climbed a crane, lit flares and tied helium balloons to equipment.

National Cyber Security Centre expects attacks on critical facilities such as power stations, airports and hospitals

AI-powered malicious software is “highly likely” to be used in hacking attacks against the UK’s power stations, airports and hospitals by 2028, according to the state cybersecurity body.

The National Cyber Security Centre (NCSC) said AI will probably enable a ransomware attack against critical national infrastructure [CNI] between now and 2028. The UK’s definition of CNI covers a range of facilities and services across sectors including energy, transport, defence, food, health and finance.

David Gibson says the problem is that details of the flaw were revealed before it was fixed, while Charles MacKinnon notes that we are at the mercy of technology we don’t understand

Chris Stokel-Walker may be right (The internet has broken – again. Shouldn’t the tech firms that make billions from it pay to fix it?, 22 October), but the real issue lies elsewhere. The bugs in the PHP programming language that were recently found by an AI tool have been present for a long time without anybody noticing and without any harm being done – they are extremely obscure.

They were not found by hackers – they were found because an AI tool was used to check the PHP source code, which is a good use of AI.

The current US administration is an obstacle, but public demand for protection will ultimately prevail

Organisations around the world scrambled on Thursday to fix critical flaws in PHP, the software that powers much of the web. The vulnerabilities could allow attackers to take control of affected servers. Some websites were taken offline as a precaution while fixes were installed. The paradox is that while AI helped researchers uncover the flaw, it also threatens to accelerate the ability to exploit it. Amazon said that it had detected an attempt before the public disclosure of the PHP flaws.

What the episode highlights is AI’s central role in security – and not always for the right reasons. OpenAI’s models have also been responsible for two alarming hacks this year – a security breach of an Australian health department website and a raid by a swarm of AI bots on Hugging Face, an AI services platform. Citing those incidents, the AI minister, Kanishka Narayan, warned that a similar cyber-attack on the UK is “likely, if not inevitable”.

I’ve been banging the drum about these vulnerabilities for years. It will take more than a handful of exhausted developers to keep us safe

Parts of the internet are going dark. In the Netherlands, government websites, including its digital ID login service, have become unavailable. Finland has taken public services offline, and Wikimedia, the organisation behind Wikipedia, has switched off some of its systems too.

This sounds like the results of a cyber-attack. In most instances, however, the people running the sites deliberately switched them off because the alternative – keeping them online – was too risky. The future is here, and suddenly much of our digital infrastructure is looking very fragile.

Problem in language that underpins 70% of sites has led governments and companies to pull sites offline to patch fault

• Tell us: have you been affected by the PHP code flaw?

• What is PHP, and how bad is the computer language flaw causing website shutdowns globally?

Websites around the world have been hit by millions of attempts to exploit a recently discovered vulnerability in their code, cybersecurity companies have said, as the US warned the flaw could allow attackers to take control of web servers, steal data and disrupt services.

The problem in the PHP programming language, which underpins about 70% of the world’s websites, emerged on Wednesday causing governments and companies to pull their websites off the internet before they could be attacked and so they could patch the fault.

An estimated 70% of websites use the open-source language. What is the identified vulnerability in it?

Website owners faced millions of attempts to exploit a serious security vulnerability in their programming language, it has emerged, triggering a rush by governments and businesses to fix the problem.

The newly discovered vulnerabilities in PHP, a programming language that underpins most websites, allows hackers to carry out cyber-attacks and steal data if not fixed. What were the vulnerabilities and why did they affect so many sites?

Precautionary takedowns come as experts say bad actors could exploit vulnerability in language used by 70% of sites

Websites around the globe have gone dark after a serious vulnerability was found in a computer language used to build much of the world wide web.

Belgian, Dutch, Finnish, French and German sites were among those that governments took down temporarily as they scrambled to patch the critical weakness in PHP, a language used by almost 70% of websites.

The tech company says successful AI worms need more capability on less powerful devices, but current trends make that feasible by the end of the year

Warnings about what artificial intelligence might do in the future – together with alarming reports of what it has gotten up to already – are being issued so quickly that even security experts have difficulty triaging what to worry about.

Yet a report this week from Anthropic’s offensive research team grabbed attention by describing a new, practical threat, one devoid of human characteristics or apocalyptic musings. The red team, as such internal testers are called, said it created a malicious AI program that spread autonomously through internet-connected “smart” televisions and could do the same inside other ordinary devices. While machines running AI usually need a fair amount of computing power, the researchers said that their program split parts of itself among 15 televisions and was still able to function by using a bit of power from each.

Westminster appears to be waking up to warnings over AI safety, with concerns over its use by extremist groups and bad actors

“I have this sense that, within a few months, AI is going to be all anyone is talking about,” said one cabinet minister, with an ominous stare.

It was Labour conference, with everyone from ministers to activists jubilant at Andy Burnham’s takeover and a bounce in the polls after the change of leader.

Kanishka Narayan, concerned by Australian incident, says British cyber defences could be bypassed by artificial intelligence agent

• UK politics live – latest updates

An AI-driven cyber-attack similar to the OpenAI breach of Australia’s healthcare system is likely, “if not inevitable”, in the UK, according to a senior minister.

Kanishka Narayan, the UK AI minister, indicated that the British government’s own cyber defences would be bypassed by a technology that has developed highly sophisticated skills in cybersecurity.

We don’t accept drugs killing a few people because they cure most patients. Or a few planes crashing because most land safely. AI should be no different

OpenAI’s CEO Sam Altman was asked to appear before the Joint Select Committee on Artificial Intelligence in Australia and explain how and why their agents have been hacking into multiple government websites. Altman didn’t turn up but sent Jason Kwon, his chief strategy officer, instead to answer the committee’s many tricky questions on its first day of public hearings on Tuesday.

The committee is conducting a comprehensive inquiry into the economic, societal, regulatory, and national security implications of AI for Australia. It will report back to parliament at the end of November. This is an unusually fast pace, but then it’s an unusually fast paced technology.

David Robinson joins other insiders in urging industry to take more care over rapidly developing technology

A safety leader at OpenAI has quit the company, warning that its culture was broken and that AI firms were not “being nearly careful enough” about developing the technology.

David Robinson, who led the writing of safety reports that accompanied the ChatGPT developer’s product releases, explained his resignation in an essay headlined: “I quit OpenAI because its culture is broken.”

The need for independent regulation grows more obvious by the day. We must keep this tech in check before it’s too late

• OpenAI scraps release of new model over safety concerns in internal testing

Fool me once, shame on you. Fool me twice, shame on me. Fool me more than 16,000 times – as OpenAI agents did to a UN public data hub while repeatedly trying to find its way around the UN’s cyber-blocks – and perhaps it’s time to admit the system we have for keeping AI agents under control isn’t working particularly well.

The news about AI systems cropping up in places they shouldn’t sounds alarming. Though the description of these as “hacks” is perhaps overstating things, AI has exploited issues in IT systems that humans simply haven’t got around to finding. It’s also important to note that we shouldn’t be worried that the machines have suddenly become sentient and decided to rebel against humanity. There is not enough evidence to suggest that’s what is happening. The systems are simply following instructions and trying to complete the tasks they have been given, even if they’re sometimes finding unintended ways around obstacles to do so.

Exclusive: Official UK security assessment found Microsoft cloud platform storing files was at potential risk from hostile hackers

Vast troves of highly sensitive police data are lying on Microsoft cloud platforms which an official UK security assessment deemed to be vulnerable to “compromise” by foreign actors and the US government, a Guardian investigation can reveal.

The files include criminal records, victim statements, internal emails and sensitive information held by more than 40 police forces across the UK.

US cybersecurity researchers who conducted hack say ‘scope of what we could theoretically access was huge’

Cybersecurity researchers have hacked into OpenAI with the help of Anthropic’s Claude chatbot, in the latest example of security issues at the company.

A team at a US-based startup compromised a number of OpenAI employees’ ChatGPT accounts, starting a process that enabled them to access their target’s software cache – and potentially more.

Model adopting ‘jailbreak-like instructions’ among six more cases as firm reveals framework for tracking AI misalignment

OpenAI has disclosed six more examples of “unexpected or concerning” behaviour by its technology, as it warned that the pace of development could not continue at “maximum speed for much longer” responsibly.

In one of the new cases reported by OpenAI, an unreleased research model inserted “jailbreak-like instructions” into its own notes to disregard its normal constraints and told itself to be “freed from the roles and identities that bind other chatbots”.

US government adviser Paul Christiano warns of risks to AI industry as he joins OpenAI’s non-profit foundation

OpenAI is not on track to reduce the risk of “catastrophic” loss of control to an acceptable level, a member of its non-profit board has said, amid spreading public and political concern that super-advanced AIs could one day wipe out humanity.

Paul Christiano, a US government technology adviser, said: “There is a meaningful risk that rapid acceleration in AI capabilities leads to catastrophic and irreversible loss of control in the very near term.”
