• TCS says none of its systems or users were affected in Marks and Spencer attack
• M&S was hit by a major cyberattack earlier in 2025
• TCS vowed an investigation, but has offered little information so far

The third-party supplier many have blamed for the major cyberattack against Marks and Spencer (M&S) has revealed its first findings of an internal investigation into its role in the incident.

Tata Consultancy Services (TCS) has said none of its "systems or users were compromised" as part of the cyberattack.

"As no TCS systems or users were compromised, none of our other customers are impacted" independent director Keki Mistry told its annual shareholder meeting, Reuters reports.

TCS role and investigation

M&S was apparently hit by the attack on April 22, revealing news of the incident several days later.

Following an initial probe, experts proposed that the attackers were able to break into its systems by compromising workers at TCS, which has provided third-party services to M&S for over a decade on Sparks, the retailer's customer reward scheme.

In 2023, TCS also reportedly secured a $1 billion contract to modernize M&S' legacy technology across its supply chain and omni-channel sales, aiming to boost online sales.

TCS, part of the massive Tata Group conglomerate, was reported to be carrying out a full investigation, but has remained quiet until this unexpected (and brief) mention.

M&S has forecast the attack could cost it around £300 million in lost operating profit in its financial year.

It was recently revealed the hackers contacted M&S CEO Stuart Machin in a mocking email the day after the attack, demanding payment for the attack.

This email was sent from the DragonForce hacking collective, which carries out such attacks in return for payment or reward from other parties in exchange for a cut of any ransom payments.

M&S has not confirmed whether it has paid a ransom to the hackers, but did admit some customer data was stolen in the attack. This did not include any passwords or card or payment details, but home addressess, phone numbers and dates of birth may have been affected.

Anyone concerned their data may have been taken, we recommend using a dark web monitoring service, or using a breach monitor such as Have I Been Pwned to check for potential exposures.

TCS has not yet responded to a TechRadar Pro request for comment.

With each passing day, AI is becoming more intelligent, more sophisticated, and more valuable to businesses worldwide. The opportunities it presents are endless – but only if brands are willing to embrace the new tech-driven business landscape and keep pace with rapid change.

There are many ways AI tools can be leveraged to work smarter, save time, reduce costs, and unlock new opportunities. Here are some tips and tricks to get you started…

1. Use AI to Cut Through the Data Noise

Recent breakthroughs in machine learning, natural language processing, and IT automation mean businesses can now access vast amounts of valuable internal and external data. High-quality data is critical to understanding your audience, spotting unmet needs, and tailoring strategies that truly resonate, but simply having access to more data doesn’t automatically translate into better outcomes.

Businesses must find ways to sift through the noise - and that’s where AI becomes invaluable. By using AI-powered tools, companies can extract actionable insights faster, more accurately, and at a larger scale, providing business leaders with a clear understanding of the steps needed to drive growth within their sector.

2. Accelerate Decision-Making with AI Insights

When applied correctly, AI-powered insights can dramatically enhance decision-making. Machine learning algorithms can process extensive datasets in seconds, allowing businesses to swiftly adapt to market changes and optimize pricing strategies.

AI can also analyze consumer behavior and competitor activity in real time, automatically adjusting pricing, marketing, and inventory strategies to maintain competitiveness - all while freeing your teams to focus on higher-value work that directly impacts profitability and operational efficiency.

3. Stay Ahead by Predicting Emerging Trends

One of AI’s greatest strengths lies in its ability to predict shifts before they happen. Traditional market research relies on historical data, while AI-powered research looks forward, identifying emerging trends early.

Businesses can monitor social media, search behavior, and purchasing patterns with AI to predict what’s coming next — whether that's the next retail craze or the next big opportunity in your sector.

Companies are already capitalizing on AI to help them do this. For example, fashion brands are using AI to forecast style trends from TikTok, while FMCG companies are tracking real-time sentiment to guide product innovation.

4. Personalize Customer Experiences at Scale

Personalization has become the gold standard in customer engagement, and AI is the ultimate engine behind it. Ecommerce platforms use AI-powered recommendation engines to suggest products based on past behavior. Streaming giants like Netflix and Spotify use it to curate content that keeps users coming back.

By tapping into consumer data, AI allows businesses to deliver highly personalized experiences - increasing customer satisfaction, loyalty, and ultimately, revenue. AI-driven chatbots and virtual assistants also ensure faster, more consistent customer support, minimizing human error while boosting brand connectivity.

5. Prioritize Ethical AI and Empower Your Workforce

As AI becomes central to operations, businesses must also prioritize responsible use. Machines are only as effective as the ethical frameworks behind them. Rather than replacing your workforce, AI should equip your employees with powerful tools to help them perform at their very best. Forward-thinking companies are investing in reskilling programs, ensuring their employees understand AI’s role and can work alongside it to create even greater value.

Meanwhile, AI companies must also stay at the cutting edge of innovation, continuously adapting our services to meet the changing needs of businesses operating in an increasingly complex, tech-driven world.

The Bottom Line

Intelligent application of AI is rapidly becoming the new foundation of business success. Companies that integrate AI into their strategy, decision-making, and customer engagement processes today will be the ones leading their industries tomorrow. Those who act now will gain a competitive edge: operating with greater agility, efficiency, and precision, freeing up valuable time and resources to focus on innovation and growth.

I've tested a new coffee maker every month for the past year here at TechRadar, and there have been some real gems.

The Jura J10, for instance, is a fully automatic powerhouse for creating hot and cold beverages at the touch of a button, while the manual Smeg Mini Pro is frankly gorgeous, and excellent for consistency.

However, no matter how many other machines I try, there's still just one sitting on my kitchen counter at the end of the day: the Gaggia Classic Pro.

It's a very popular little manual espresso machine, and for good reason. It's a lot of fun to use, it's a tinkerer's dream – and at around $500 / £400 / AU$800 it's moderately priced, too.

There's a lot to like about this machine. In our Gaggia Classic Pro review, we stated that it's a "good-looking, well-built appliance" and that "it proved super-easy to brew intense, smooth espressos with very little experimentation required."

However, when new, Lady Gaggia (as we call her at home) isn't without her quirks.

For example, there's not masses of space between the portafilter and the drip tray, which means you can only fit small cups underneath (I usually use a shot glass with measures printed on the side). Plus, the tray is so narrow you can forget about putting a scale underneath to weigh the coffee as it drips out.

There's no PID controller to keep the temperature stable like you get in some premium coffee machines, either, and the Gaggia's small boiler means you might run out of steam (quite literally) before you've finished preparing your milk.

The upside is that there's a great community of hobbyists tinkering with this hugely popular little machine, sharing advice, and even selling kits that let you modify it to your heart's content – like the example in the Reddit post below.

Guys I finally made the upgrade to a PID from Barista Gadgets. from r/gaggiaclassic

For example, US-based Barista Gadgets and UK site Shades of Coffee sell longer drip trays that can accommodate a scale, and shallower trays so you can use a larger cup. There are also devices that continually add a small amount of water to the boiler, so you can keep steaming milk for longer without it running dry.

Shades of Coffee makes and sells heads for the machine's steam arm too, plus colored lighting kits to illuminate the water tank so you can see the level more easily (and that make it look like a gaming PC). And if your Gaggia still doesn't look cool enough, you can even pick up a wooden knob to replace the plastic one that controls the steam pressure.

Feeling really geeky? Take a look at Gaggiuino, which is an open source project that aims to make your machine as consistent as possible, letting you control the pressure, temperature, and flow of each shot.

Want to learn more? Take a look at the Gaggia Classic subreddit, where you'll find a whole community of friendly coffee-lovers sharing their tips for mods, maintenance and repairs, and generally having fun. If you're looking for a new hobby, this is the best coffee maker for you.

• Despite the noise from new tools, report finds email still drives the most critical business communication
• Instant messaging is quick, but only email delivers structure, traceability, and professional clarity
• Most modern tools serve teams, but email still connects entire organizations reliably and securely

As companies continue to adopt the likes of AI, instant messaging, and cloud-based online collaboration platforms, one might expect email to fade into the background.

However, business email appears to be getting more indispensable, and it turns out that when accountability and structure matter, email still leads.

The recent State of Business Email 2025 report from Exclaimer, based on over 4,000 responses from global IT leaders has revealed while communication stacks are expanding, they are still anchored by email.

Why email remains a serious communication channel

Today’s workplace is more digitally connected than ever, yet paradoxically more fragmented, with tools like Notion, Asana, and monday.com are lauded for improving collaboration, and 89 percent of global IT leaders consider video conferencing crucial to operations.

However, these tools often fail to achieve company-wide standardization, as their adoption is typically uneven, influenced by department needs, company size, or maturity - and as a result, communication can become fractured across platforms.

This complexity forces many IT teams to fall back on email, which remains the most reliable means of ensuring continuity across teams and geographies.

According to the research, nearly half of all internal and external communications still run through email, more than any other tool. For sensitive or high-stakes messages, email is preferred because it offers traceability, permanence, and clarity.

“We’ve never had more ways to connect and collaborate at work, but email remains the backbone of business communication,” said Vicky Wills, Chief Technology Officer at Exclaimer.

“As new tools emerge, the challenge for IT leaders isn’t just picking platforms, it’s making sure they’re implemented strategically. That’s how we build communication environments that are clear, connected, and fit for the future.”

Departments like IT (56 percent), HR, customer success, and finance continue to rely on email, the study found, as these are roles that require precision, auditability, and structured messaging, features that instant messaging platforms often lack.

Instant messaging is undeniably a central part of modern business, and 89 percent of IT leaders rate it as important as email.

However, while instant messaging is used for speed and informal check-ins, email handles the tasks that must be reviewed, logged, and revisited.

For small and mid-sized businesses looking to streamline communication while maintaining oversight, email remains central.

• Push notifications are now being used as malware delivery systems, and users are unknowingly subscribing to them
• Fake CAPTCHA prompts are now the gateway to persistent browser hijacks and phishing attacks
• WordPress sites are quietly hijacking users through invisible DNS commands and shared JavaScript payloads

Recent investigations have revealed a troubling alliance between WordPress hackers and commercial adtech companies, creating a vast infrastructure for distributing malware on a global scale.

Research from Infoblox Threat Intel found at the core of this operation is VexTrio, a traffic distribution system (TDS) responsible for rerouting web users through layers of fake ads, deceptive redirects, and fraudulent push notifications.

The report claims several commercial firms, including Los Pollos, Partners House, and RichAds, are entangled in this network, serving as both intermediaries and enablers.

Los Pollos connection and a failed shutdown

Infoblox initially tied Los Pollos to VexTrio when the former was implicated in Russian disinformation campaigns.

In response, Los Pollos claimed it would terminate its "push link monetization" model.

Despite this, the underlying malicious activity continued as attackers shifted to a new TDS known as Help, which was eventually linked back to VexTrio.

WordPress vulnerabilities served as the entry point for multiple malware campaigns, as attackers compromised thousands of websites, embedding malicious redirection scripts. These scripts relied on DNS TXT records as a command-and-control mechanism, determining where to send web visitors.

Analysis of over 4.5 million DNS responses between August and December 2024 revealed that even though various malware strains appeared separate, they shared infrastructure, hosting, and behavioral patterns that all led to VexTrio or its proxies, including Help TDS and Disposable TDS.

JavaScript across these platforms exhibited the same functions, disabling browser navigation controls, forcing redirects, and luring users with fake sweepstakes.

Interestingly, these TDSs are embedded within commercial adtech platforms that present themselves as legitimate affiliate networks.

"These firms maintained exclusive relationships with 'publisher affiliates,' in this context, the hackers, and knew their identities," researchers noted.

Push notifications have emerged as a particularly potent threat vector. Users are tricked into turning on browser notifications by using fake CAPTCHA prompts.

Hackers then send phishing or malware links after a user subscribes, evading firewall settings and even the best antivirus programs.

Some campaigns route these messages through reliable services like Google Firebase, making detection significantly more difficult.

The overlap between adtech platforms, including BroPush, RichAds, and Partners House, further complicates attribution.

Misconfigured DNS systems and reused scripts suggest a common backend, possibly even a shared development environment.

To tackle the risk, users should avoid turning on suspicious browser alerts, use tools that offer zero-trust network access (ZTNA), and be cautious when using CAPTCHA prompts.

By updating WordPress and monitoring for DNS anomalies, site administrators can reduce the likelihood of compromise.

Adtech companies, however, might have the actual lever and the key to closing these operations if they choose to act.

One of Marvel's youngest superheroes hits the small screen this month.

So far the summer months have been packed with fresh titles across a lot of the best streaming services. Now that July is near, it's Hulu turn to impress again.

Compared to last month's schedule, which saw the return of shows like FX's The Bear, Hulu is bringing even more new TV shows to its catalog – 82 to be exact! But out of all the new arrivals the return of the irreverent sitcom It's Always Sunny in Philadelphia is coming back for a 17th season. Yep, it's still going strong.

There's no doubt that Hulu is one of the best streaming platforms for TV shows but that doesn't mean it's lacking in the movie department, and there'll be over 50 new movies on July 1 alone. I've got my eye on guilty pleasures Bride Wars (2009), Easy A (2010), and Dirty Dancing (1987).

• Future AI memory chips could demand more power than entire industrial zones combined
• 6TB of memory in one GPU sounds amazing until you see the power draw
• HBM8 stacks are impressive in theory, but terrifying in practice for any energy-conscious enterprise

The relentless drive to expand AI processing power is ushering in a new era for memory technology, but it comes at a cost that raises practical and environmental concerns, experts have warned.

Research by Korea Advanced Institute of Science & Technology (KAIST) and Terabyte Interconnection and Package Laboratory (TERA) suggests by 2035, AI GPU accelerators equipped with 6TB of HBM could become a reality.

These developments, while technically impressive, also highlight the steep power demands and increasing complexity involved in pushing the boundaries of AI infrastructure.

Rise in AI GPU memory capacity brings huge power consumption

The roadmap reveals the evolution from HBM4 to HBM8 will deliver major gains in bandwidth, memory stacking, and cooling techniques.

Starting in 2026 with HBM4, Nvidia's Rubin and AMD’s Instinct MI400 platforms will incorporate up to 432GB of memory, with bandwidths reaching nearly 20TB/s.

This memory type employs direct-to-chip liquid cooling and custom packaging methods to handle power densities around 75 to 80W per stack.

HBM5, projected for 2029, doubles the input/output lanes and moves toward immersion cooling, with up to 80GB per stack consuming 100W.

However, the power requirements will continue to climb with HBM6, anticipated by 2032, which pushes bandwidth to 8TB/s and stack capacity to 120GB, each drawing up to 120W.

These figures quickly add up when considering full GPU packages expected to consume up to 5,920W per chip, assuming 16 HBM6 stacks in a system.

By the time HBM7 and HBM8 arrive, the numbers stretch into previously unimaginable territory.

HBM7, expected around 2035, triples bandwidth to 24TB/s and enables up to 192GB per stack. The architecture supports 32 memory stacks, pushing total memory capacity beyond 6TB, but the power demand reaches 15,360W per package.

The estimated 15,360W power consumption marks a dramatic increase, representing a sevenfold rise in just nine years.

This means that a million of these in a data center would consume 15.36GW, a figure that roughly equals the UK’s entire onshore wind generation capacity in 2024.

HBM8, projected for 2038, further expands capacity and bandwidth with 64TB/s per stack and up to 240GB capacity, using 16,384 I/O and 32Gbps speeds.

It also features coaxial TSV, embedded cooling, and double-sided interposers.

The growing demands of AI and large language model (LLM) inference have driven researchers to introduce concepts like HBF (High-Bandwidth Flash) and HBM-centric computing.

These designs propose integrating NAND flash and LPDDR memory into the HBM stack, relying on new cooling methods and interconnects, but their feasibility and real-world efficiency remain to be proven.
