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.

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.

Company ordered to stop work at two sites in country, which has found itself at forefront of tech firms’ latest push

Behind a wire fence lies a vast gaping wound of earth. Before Google’s arrival a few months ago, an estimated quarter of a million trees occupied the 330 hectares (815 acres) of forest near the town of Muhos in rural northern Finland. Now they are all gone.

After the tech company illegally stripped the entire area to build a datacentre – taking even the top soil with it – all that remains is a vast expanse of mud indented with the trail marks of machinery, puddles and mounds of earth, roots and branches. Residents say that brown water flowing off the site is going into a stream that feeds the Oulujoki River.

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

Websites across the world have been taken offline in the past day as governments and businesses work to patch newly discovered vulnerabilities in PHP, a programming language that underpins much of the internet. The exposed flaw would have allowed hackers to carry out cyber-attacks. What were the vulnerabilities and why did they affect so many sites?

The director has turned Kazuo Ishiguro’s acclaimed novel about an ailing adolescent and her glitchy robot friend into a thought-provoking film. What do the pair think this story says about tech, love and grief?

In the wings of the London film festival, a group of young influencers are discussing their personal highlights. Klara and the Sun, says one, and her colleagues agree. It’s not just that the film is still so fresh in their memory, or that they have gathered today to meet its creators and stars. Klara is funny and moving; it’s their festival favourite so far. I relay this exchange to Taika Waititi, the film’s director, who is sipping bottled water in a room down the hall. His gaze widens. He almost chokes. “Thank God!” he exclaims with just a bit too much heat.

Everybody has a perfect film, just as everybody has a perfect friend, and they vary because everybody is different. In the film, sick 14-year-old Josie loves her discontinued robot doll Klara, whereas most kids her age opt for brighter, shinier models. And the young influencers love Klara and the Sun – Waititi’s adaptation of Kazuo Ishiguro’s acclaimed novel – while most older critics vehemently, violently disagree. All of which shows that there’s no accounting for taste, that people are confounding, and that our hearts and our brains are not always in sync. That keeps life interesting. It’s partly what the film is about. “The emotions that we give very simple labels to are really complex,” says Ishiguro, who is seated alongside the director. “The thing we call love, for example, is incredibly noisy and multifaceted. Nobody knows what the hell love is.”

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.
