MPs press outsourcer TCS over Jaguar cyber attack | Computer Weekly


The UK government has reached out to Indian IT outsourcer Tata Consultancy Services (TCS) seeking answers from CEO Krithi Krithivasan over its alleged involvement in the ongoing cyber attack at Jaguar Land Rover (JLR), which has brought production at the firm to a standstill.

TCS was briefly linked to the Scattered Spider attack on Marks and Spencer (M&S) earlier this year and did conduct its own investigation into whether or not its systems were the initial source of the incident.

However, in June 2025, the IT giant told shareholders that it had found no TCS systems or users were compromised, and no other customers impacted. A representative for the company said the “purview of the investigation does not include TCS”.

Nevertheless, unconfirmed public speculation has continued to link TCS to other intrusions and attacks conducted by Scattered Spider and associated hacking groups, including incidents at Qantas – a TCS customer – and other airlines.

In the letter, Liam Byrne MP, in his capacity as chair of the cross-bench Business and Trade Committee, said he was trying to find out more information about both the JLR cyber attack and the incidents at M&S and Co-op Group. JLR is coincidentally backed by the wider Tata organisation.

Byrne said the Committee was looking to establish more details on TCS’ role as a service provider to all three affected firms – including the scope of services provided to date; whether TCS is conducting or will conduct an internal investigation into the JLR incident; and whether it has conducted or concluded an investigation into the M&S and Co-op incidents and what it found.

Byrne also asked for details of how many UK organisations work with TCS, with a particular emphasis on those working in the 13 sectors that Westminster currently defines as critical national infrastructure (CNI), and the total value of services contracts it holds in the UK.

On Monday 29 September, JLR said it was “taking further steps” in a “controlled, phased restart” of its manufacturing operations, after receiving a £1.5bn loan guarantee from the government.

“We are informing colleagues, retailers and suppliers that some sections of our manufacturing operations will resume in the coming days,” the firm said. “We continue to work around the clock alongside cyber security specialists, the UK government’s NCSC [National Cyber Security Centre] and law enforcement to ensure our restart is done in a safe and secure manner.”

The crisis has led to production shutdowns across JLR – including at its plants in Brazil, India and Slovakia – and caused a series of cascading effects that are being keenly felt across the UK automotive industry.

As Britain’s largest extant carmaker, JLR is a major force in the wider supply chain, and many smaller companies have had to make cuts of their own in response. According to the Business and Trade Committee, at least one JLR supplier had been forced to sell machinery and other assets. Others have been cutting back on staff hours, leaving thousands of workers out of pocket.

TCS had not responded to a request for comment from Computer Weekly at the time of publication.

Media professor says AI’s superior ability to formulate thoughts for us weakens our ability to think critically

Media professor says AI’s superior ability to formulate thoughts for us weakens our ability to think critically

AI’s superior ability to formulate thoughts and statements for us weakens our judgment and ability to think critically, says media professor Petter Bae Brandtzæg.

No one knew about Chat GPT just three years ago. Today, 800 million people use the technology. The speed at which AI is rolling out breaks all records and has become the new normal.

Many AI researchers, like Brandtzæg, are skeptical. AI is a technology that interferes with our ability to think, read, and write. “We can largely avoid , but not AI. It is integrated into social media, Word, online newspapers, email programs, and the like. We all become partners with AI—whether we want to or not,” says Brandtzæg.

The professor of media innovations at the University of Oslo has examined how AI affects us in the recently completed project “An AI-Powered Society.”

The freedom of expression commission overlooked AI

The project has been conducted in collaboration with the research institute SINTEF. It is the first of its kind in Norway to research generative AI, that is, AI that creates content, and how it affects both users and the public.

The background was that Brandtzæg reacted to the fact that the report from the Norwegian Commission for Freedom of Expression, which was presented in 2022, did not sufficiently address the impact of AI on society—at least not generative AI.

“There are studies that show that AI can weaken . It affects our language, how we think, understand the world, and our moral judgment,” says Brandtzæg.

A few months after the Commission for Freedom of Expression report, ChatGPT was launched, making his research even more relevant.

“We wanted to understand how such generative AI affects society, and especially how AI changes social structures and relationships.”

AI-Individualism

The social implications of generative AI is a relatively new field that still lacks theory and concepts, and the researchers have therefore launched the concept of “AI-individualism.” It builds on “network individualism,” a framework which was launched in the early 2000s.

Back then, the need was to express how smartphones, the Internet, and social media enabled people to create and tailor their social networks beyond family, friends, and neighbors.

Networked individualism showed how technology weakened the old limits of time and place, enabling flexible, personalized networks. With AI, something new happens: the line between people and systems also starts to blur, as AI begins to take on roles that used to belong to humans.

“AI can also meet personal, social, and emotional needs,” says Brandtzæg.

With a background in psychology, he has for a long time studied human-AI relationships with chatbots like Replika. ChatGPT and similar social AIs can provide immediate, personal support for any number of things.

“It strengthens individualism by enabling more autonomous behavior and reducing our dependence on people around us. While it can enhance personal autonomy, it may also weaken community ties. A shift toward AI-individualism could therefore reshape core social structures.”

He argues that the concept of “AI-individualism” offers a new perspective for understanding and explaining how relationships change in society with AI. “We use it as a relational partner, a collaborative partner at work, to make decisions,” says Brandtzæg.

Students choose chatbot

The project is based on several investigations, including a questionnaire with open-ended answers to 166 on how they use AI.

“They (ChatGPT and MyAI) go straight to the point regarding what we ask, so we don’t have to search endlessly in the books or online,” said one high school student about the benefits of AI.

“ChatGPT helps me with problems, I can open up and talk about difficult things, get comfort and good advice,” responded a student.

In another study, using an online experiment with a blind test, it turned out that many preferred answers from a chatbot over a professional when they had questions about mental health. More than half preferred answers from a chatbot, less than 20% said a professional, while 30% responded both.

“This shows how powerful this technology is, and that we sometimes prefer AI-generated content over human-generated,” says Brandtzæg.

‘Model power’

The theory of “model power” is another concept they’ve launched. It builds on a power relationship theory developed by sociologist Stein Bråten 50 years ago.

Model power is the influence one has by being in possession of a model of reality that has impact, and which others must accept in the absence of equivalent models of power of their own, according to the article “Modellmakt og styring” (online newspaper Panorama—in Norwegian).

In the 1970s, it was about how media, science, and various groups with authority could influence people, and had model power. Now it’s AI.

Brandtzæg’s point is that AI-generated content no longer operates in a vacuum. It spreads everywhere, in public reports, new media, in research, and in encyclopedias. When we perform Google searches, we first get an AI-generated summary.

“A kind of AI layer is covering everything. We suggest that the model power of social AI can lead to model monopolies, significantly affecting human beliefs and behavior.”

Because AI models, like ChatGPT, are based on dialog, they call them social AI. But how genuine is a dialog with a machine fed with enormous amounts of text?

“Social AI can promote an illusion of real conversation and independence—a pseudo-autonomy through pseudo-dialog,” says Brandtzæg.

Critical but still following AI advice

According to a survey from The Norwegian Communications Authority (Nkom) from August 2025, 91% of Norwegians are concerned about the spread of false information from AI services like Copilot, ChatGPT, and Gemini.

AI can hallucinate. A known example is a report the municipality of Tromsø used as a basis for a proposal to close eight schools, was based on sources that AI had fabricated. Thus, AI may contribute to misinformation, and may undermine user trust in both AI, service providers and public institutions.

Brandtzæg asks how many other smaller municipalities and public institutions have done the same and he is worried about the spread of this unintentional spread of misinformation.

He and his researcher colleagues have reviewed various studies indicating that although we like to say we are critical, we nevertheless follow AI’s advice, which highlights the model power in such AI systems.

“It’s perhaps not surprising that we follow the advice that we get. It’s the first time in history that we’re talking to a kind of almighty entity that has read so much. But it gives a model power that is scary. We believe we are in a dialog, that it’s cooperation, but it’s one-way communication.”

American monoculture

Another aspect of this model power is that the AI companies are based in the U.S. and built on vast amounts of American data.

“We estimate that as little as 0.1% is Norwegian in AI models like ChatGPT. This means that it is American information we relate to, which can affect our values, norms and decisions.”

What does this mean for diversity? The principle is that “the winner takes it all.” AI does not consider minority interests. Brandtzæg points out that the world has never before faced such an intrusive technology, which necessitates regulation and balancing against real human needs and values.

“We must not forget that AI is not a public, democratic project. It’s commercial, and behind it are a few American companies and billionaires,” says Brandtzæg.

How do ‘AI detection’ tools actually work? And are they effective?

How do ‘AI detection’ tools actually work? And are they effective?


Credit: JUSTIN JOSEPH from Pexels

As nearly half of all Australians say they have recently used artificial intelligence (AI) tools, knowing when and how they’re being used is becoming more important.

Consultancy firm Deloitte recently partially refunded the Australian government after a report they published had AI-generated errors in it.

A lawyer also recently faced after false AI-generated citations were discovered in a formal court document. And many universities are concerned about how their students use AI.

Amid these examples, a range of “AI detection” tools have emerged to try to address people’s need for identifying accurate, trustworthy and verified content.

But how do these tools actually work? And are they effective at spotting AI-generated material?

How do AI detectors work?

Several approaches exist, and their effectiveness can depend on which types of content are involved.

Detectors for text often try to infer AI involvement by looking for “signature” patterns in , , and the predictability of certain words or phrases being used. For example, the use of “delves” and “showcasing” has skyrocketed since AI writing tools became more available.

However the difference between AI and human patterns is getting smaller and smaller. This means signature-based tools can be highly unreliable.

Detectors for images sometimes work by analyzing embedded metadata which some AI tools add to the image file.

For example, the Content Credentials inspect tool allows people to view how a user has edited a piece of content, provided it was created and edited with compatible software. Like text, images can also be compared against verified datasets of AI-generated content (such as deepfakes).

Finally, some AI developers have started adding watermarks to the outputs of their AI systems. These are hidden patterns in any kind of content which are imperceptible to humans but can be detected by the AI developer. None of the large developers have shared their detection tools with the public yet, though.

Each of these methods has its drawbacks and limitations.

How effective are AI detectors?

The effectiveness of AI detectors can depend on several factors. These include which tools were used to make the content and whether the content was edited or modified after generation.

The tools’ training data can also affect results.

For example, key datasets used to detect AI-generated pictures do not have enough full-body pictures of people or images from people of certain cultures. This means successful detection is already limited in many ways.

Watermark-based detection can be quite good at detecting content made by AI tools from the same company. For example, if you use one of Google’s AI models such as Imagen, Google’s SynthID watermark tool claims to be able to spot the resulting outputs.

But SynthID is not publicly available yet. It also doesn’t work if, for example, you generate content using ChatGPT, which isn’t made by Google. Interoperability across AI developers is a major issue.

AI detectors can also be fooled when the output is edited. For example, if you use a voice cloning app and then add noise or reduce the quality (by making it smaller), this can trip up voice AI detectors. The same is true with AI image detectors.

Explainability is another major issue. Many AI detectors will give the user a “confidence estimate” of how certain it is that something is AI-generated. But they usually don’t explain their reasoning or why they think something is AI-generated.

It is important to realize that it is still early days for AI detection, especially when it comes to automatic detection.

A good example of this can be seen in recent attempts to detect deepfakes. The winner of Meta’s Deepfake Detection Challenge identified four out of five deepfakes. However, the model was trained on the same data it was tested on—a bit like having seen the answers before it took the quiz.

When tested against new content, the model’s success rate dropped. It only correctly identified three out of five deepfakes in the new dataset.

All this means AI detectors can and do get things wrong. They can result in false positives (claiming something is AI generated when it’s not) and false negatives (claiming something is human-generated when it’s not).

For the users involved, these mistakes can be devastating—such as a student whose essay is dismissed as AI-generated when they wrote it themselves, or someone who mistakenly believes an AI-written email came from a real human.

It’s an arms race as new technologies are developed or refined, and detectors are struggling to keep up.

Where to from here?

Relying on a single tool is problematic and risky. It’s generally safer and better to use a variety of methods to assess the authenticity of a piece of content.

You can do so by cross-referencing sources and double-checking facts in written content. Or for visual content, you might compare suspect images to other images purported to be taken during the same time or place. You might also ask for additional evidence or explanation if something looks or sounds dodgy.

But ultimately, trusted relationships with individuals and institutions will remain one of the most important factors when detection tools fall short or other options aren’t available.

The Best Organic Mattresses—All Certified, All Actually Tested


Organic bedding brand Coyuchi recently launched its own organic mattress, combining cotton, wool, and Dunlop latex atop individually wrapped coils. While Coyuchi’s linen sheets are excellent, I was a little nervous to try the company’s first mattress effort. Bedding is not a mattress, after all, and expertise does not always transfer across endeavors. In this case, though, it did. Coyuchi’s organic Natural REM Mattress is wonderfully firm without being too firm and perfect for those of us who lack a sleeping style and tend to sleep every which way—side, back, stomach. I was never uncomfortable.

The design starts with encased coils on a wool pad and then, like a Midwestern dip, layers in smaller coils, latex, and then wool, and tops it off with an organic cotton cover. There’s surprisingly good edge support considering the distance between the coils and the top, and the mattress provides good motion isolation as well. Coyuchi says the Natural REM can be used with or without a box spring. I tested it for a few months on a box spring and then spent a week with it just on the floor and did not notice a difference. At 11 inches deep, there’s room for a topper, though I did not feel the need.

The cotton and wool layers are GOTS-certified organic, while the Dunlop latex carries the GOLS certification. The material is undyed, which is great for anyone bothered by industrial dyes. As with most of these organic options, the Coyuchi is made without chemicals, foam, or glues. Coyuchi’s Natural REM organic mattress is made to order in the United States and comes with a 100-night trial, which means you can get a full refund if it doesn’t work for you. —Scott Gilbertson
