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.

Using a fake DOB or leaving the field blank when making an online account can offer protection from identity theft

You get a call from your bank saying there has been suspicious activity on your account. They read out your name, address and date of birth so you are happy it is a legitimate caller.

But you are talking to criminals who have used your date of birth as part of a web of verifying information to convince you they are someone else.

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.

Information released by Distributed Denial of Secrets is the third such government data disclosure in the last month

Data identifying more than 41,000 employees and contractors for the US Department of Homeland Security (DHS) was released on Wednesday in an unprecedented leak that reveals how the agency is organized. The records, which were made public by the transparency non-profit Distributed Denial of Secrets, reference operation names, surveillance programs and information on undercover initiatives.

The DHS did not immediately return a message seeking comment.

‘Session cookies’ are a primary target for hackers letting them hijack and use your accounts

You’ve had a busy morning of life admin, logging into various accounts to check balances and make payments. At the end of a productive few hours you close your laptop and move on to your next job.

What you don’t know is that fraudsters have hijacked your session with the bank and are now able to access your account. You are the victim of cookie theft, which belongs to a type of fraud known as “session hijacking”.

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”.

Websites around the world have been taken offline as governments and businesses scramble to fix a flaw in the computer language PHP. There are fears that hackers could exploit the vulnerability to steal data, take control of web servers and disrupt services. Millions of attempts have already been made to attack websites since the issue with the programming language was revealed, cybersecurity companies have said.

We’d like to hear from small businesses that have been affected by the PHP code flaw. Did you have to take you website offline? Did you manage to patch the fault?

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 National Security Agency 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.

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.

Apparent attempt to hack Rade Bajić’s iPhone comes amid efforts to undermine landmark criminal case

A Serbian prosecutor who investigated the authorities’ allegedly illegal scheme to help the Trumps build a tower in Belgrade has been targeted with advanced spyware, expert analysis indicates.

The finding suggests a disturbing new element in the authoritarian Serbian regime’s campaign to undermine what is believed to be the first criminal case related to global moneymaking drive of the US president’s family, which critics describe as a “pay to play” scheme trading the Trump administration’s favour for business opportunities.

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.

In the west the technology comes with at least some effort to provide security and a benign intent – not so from China

There is much to fear from artificial intelligence developed in China and handed to businesses and governments in the west almost free of charge.

Every month Chinese AI developers such as DeepSeek and Xiaomi dispatch the latest versions of their “open-weight” models that allow users to take the core software and use it without paying an expensive ongoing licence.

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.

Whether it was youngsters proving their skills or state sabotage, Europe’s most hacked country was left with a mountain of waste after food began cooking in freezers

Shortly before midnight last Sunday, the digital thermostats controlling hundreds of supermarket cold aisles across France began to flicker and rise.

In a “bizarre and unprecedented” cyber-attack, hackers had remotely overridden the temperature settings on thousands of freezers, fridges and chiller cabinets pushing them from as low as -27C (-16.6F) to well over 50C (122F).

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.
