A new Nozomi Networks report has found that 94 per cent of Wi-Fi networks lack proper protection against deauthentication attacks, leaving them vulnerable to disruption and infiltration.

The analysis of 500,000+ wireless networks revealed that only 6 per cent had enabled Management Frame Protection (MFP), a key security feature preventing attackers from forcing devices offline using spoofed deauthentication frames. These denial-of-service (DoS) attacks can disrupt connectivity and serve as a gateway for data theft and system intrusions.

Deauthentication attacks exploit weaknesses in Wi-Fi protocols, allowing hackers to disconnect devices, intercept data, and launch man-in-the-middle attacks. Nozomi warns that state-linked hacking groups, such as Volt Typhoon, have used these tactics to target critical infrastructure, healthcare, and industrial networks.

To mitigate risk, businesses should enable 802.11w (MFP), upgrade to WPA3 encryption, and monitor networks for suspicious activity. Regular wireless security audits and strong segmentation are also essential to prevent attackers from exploiting these vulnerabilities.

A new report from the Rhodium Group claims that advanced geothermal energy could power nearly all new data centres by 2030.

A Stable, Renewable Solution

With the exponential rise in artificial intelligence (AI) and cloud computing driving unprecedented demand for electricity, the energy consumption of data centres is a growing concern. However, the report suggests that tapping into the Earth’s heat could provide a stable, renewable solution to this looming energy crisis.

The Data Centre Energy Problem

Data centres are essentially the backbone of the digital economy, hosting everything from cloud storage to AI model training. However, their hunger for power (and water) is becoming a pressing issue. For example, according to the Rhodium Group, electricity demand from data centres in the US has surged from 2 per cent of total consumption in 2020 to around 4.5 per cent in 2024. Projections indicate this could rise to as much as 12 per cent by 2028.

Much of this surge comes from the rapid expansion of AI, with models such as ChatGPT, Google Gemini, and Microsoft Copilot requiring massive computational power. The grid is struggling to keep pace, with utilities and regulators facing growing challenges in ensuring reliable, low-carbon electricity supply.

What Is Geothermal Energy?

Geothermal energy harnesses heat stored beneath the Earth’s surface, converting it into electricity or direct heating. Traditionally, geothermal power plants were limited to areas where hot water or steam naturally rises close to the surface, such as Iceland or parts of the western US.

However, advancements in enhanced geothermal systems (EGS), which use deep drilling and hydraulic fracturing techniques to unlock heat from otherwise inaccessible rock formations, are now changing the game. For example, according to the US Department of Energy, EGS could unlock up to 90 gigawatts (GW) of geothermal capacity in the US alone, providing a vast, untapped source of clean energy.

Why Geothermal Could Meet Data Centre Demand

The Rhodium Group’s report estimates that under current trends, geothermal could provide up to 64 per cent of new data centre electricity demand by 2030. If data centre developers strategically site their facilities in areas with the best geothermal resources, this figure could rise to 100 per cent!

In practical terms, this means geothermal could quadruple its current installed capacity in the US, from 4GW today to approximately 16GW by the end of the decade. Crucially, the cost of geothermal energy is expected to be competitive with existing power sources, ranging from $50 to $75 per megawatt-hour (MWh) (on par with current grid electricity prices for data centres).

Real-World Examples of Geothermal in Action

A number of innovative startups are already proving the feasibility of geothermal-powered data centres. These include:

– Fervo Energy, founded by former oil and gas engineers, has been pioneering horizontal drilling techniques to boost geothermal output. The company secured over $200 million in investment in 2024 and has significantly reduced drilling costs.

– Bedrock Energy is focusing on space-constrained urban environments. Their deep-drilling approach enables office buildings and data centres to tap into geothermal heat with a small footprint.

– Quaise Energy has developed a breakthrough technology that uses high-powered microwaves to vaporise rock, allowing them to drill as deep as 12.4 miles (20km). At these depths, temperatures exceed 1,000°F, providing an almost limitless source of heat.

– Sage Geosystems is taking a different approach, using geothermal wells to store energy. Water is injected under pressure and later released to generate electricity, similar to an underground hydroelectric dam.

The Benefits of Geothermal for Data Centres

Geothermal energy offers a host of advantages for data centre operators, most notably:

– 24/7 reliability. Unlike wind or solar, geothermal provides continuous, baseload power with 90 per cent+ capacity factors.

– A low carbon footprint. Geothermal plants emit little to no greenhouse gases, aligning with tech companies’ aggressive net-zero targets.

– Grid independence. By using behind-the-metre geothermal installations, data centres can bypass lengthy grid connection delays, reducing wait times for power.

– Cost stability. Unlike natural gas, which is subject to price volatility, geothermal energy provides long-term price certainty.

The Challenges of Scaling Geothermal

However, while the potential is pretty clear, there are some significant hurdles to overcome before geothermal can power the next wave of data centres. These include:

– High upfront costs. Deep drilling and well stimulation require significant capital investment. However, costs are falling as technology advances.

– Permitting delays. In the US, for example, securing permits for geothermal projects can take up to 10 years! Streamlining regulatory approvals is crucial to accelerating deployment.

– Geographic constraints. While EGS expands geothermal’s reach, the best sites are still concentrated in the western US, meaning some data centres may have to relocate or use hybrid energy strategies.

– Infrastructure readiness. Drilling rigs, turbines, and skilled labour all need to scale rapidly to meet growing demand. Leveraging expertise from the oil and gas sector could help bridge this gap.

What Does This Mean For Your Organisation?

Geothermal energy could be a real and practical way to address the growing electricity demands of data centres while aligning with sustainability goals. The technology is proven, its reliability is unmatched among renewables, and its potential is vast. However, realising this potential requires significant investment, regulatory reform, and strategic siting of new facilities.

For data centre operators, integrating geothermal could reduce dependence on fossil fuels and offer long-term cost stability. For policymakers, streamlining permitting processes and incentivising geothermal development will be key to unlocking its full potential. Meanwhile, investors and energy companies have a chance to shape a growing market by developing innovative drilling and power generation techniques.

For UK businesses, the need for cleaner, more stable energy sources is just as pressing in this country, where data centre energy demand is rising rapidly. While the UK lacks the geothermal resources of the US, investment in energy innovation, including geothermal heating and advanced drilling techniques, could provide valuable lessons and opportunities. Also, British companies specialising in energy technology, infrastructure, and financing may find growing international demand for their expertise.

The question, therefore, is no longer whether geothermal can support the data centre boom, but how quickly the industry can scale to meet demand. With the right mix of investment, policy support, and technological innovation, the heat beneath our feet could soon be powering the digital world in ways previously unimaginable.

UK banking customers who have faced repeated IT failures are set to receive millions in compensation, following a damning Treasury Committee investigation into the scale and impact of these outages.

Nine Banks

The inquiry revealed that in the past two years alone, nine major banks and building societies have suffered more than a month’s worth of system failures, leaving millions unable to access their money when they needed it most.

How Big Is The Problem?

The inquiry revealed that between January 2023 and February 2025, major high street banks (including Barclays, HSBC, Lloyds, Nationwide, Santander, and NatWest) collectively experienced at least 803 hours of IT outages. That’s more than 33 days of service disruptions, affecting customers’ ability to make payments, transfer funds, and in some cases, even access their own accounts.

To make matters worse, some of the most disruptive outages occurred on key dates, including payday, adding to the distress caused. For many, these incidents resulted in late bill payments, missed wages, and even the inability to complete major transactions – a situation that has been described as ‘deeply unsettling’ by campaigners.

Many Living Pay Cheque to Pay Cheque

Commenting on the findings of the report, Dame Meg Hillier, Chair of the Treasury Committee, did not hold back in her criticism of the situation, stating: “For families and individuals living pay cheque to pay cheque, losing access to banking services on payday can be a terrifying experience. The fact there has been enough outages to fill a whole month within the last two years shows customers’ frustrations are completely valid.”

Which Banks Are Paying Out and How Much?

As scrutiny on the sector intensifies, it seems that some banks have now set aside millions to compensate affected customers. Here’s what each bank is paying and why:

– Barclays… The worst-hit bank in the report, Barclays is expected to pay between £5 million and £7.5 million for inconvenience and distress caused by various outages, with the total amounting to £12.5 million over the past two years.

– Bank of Ireland… The second-largest compensation payout, with £350,000 being distributed to impacted customers.

– NatWest… Has recorded 13 major incidents and will be compensating customers £348,000.

– HSBC… With 32 separate IT failures, HSBC has set aside £232,697 in compensation payments.

– Lloyds… Customers will receive £160,000 following 12 incidents of service disruption.

– Nationwide… The building society has paid out £77,452 due to system failures.

– Santander… Despite 24 incidents, its compensation stands at just £17,000.

– AIB… Paying out a nominal £590 in compensation.

The scale of Barclays’ payout alone shows the gravity of the problem, particularly given that its most recent failure in January left 56 per cent of online payments failing on payday, with some customers unable to complete house moves and others left stranded without funds.

What It Could Mean for Customers

For banking customers, these payouts are likely to come as both a relief and a frustration. For example, while the compensation acknowledges the distress caused, it’s likely to do little to restore confidence in the reliability of banking services. Many customers have already expressed concerns that IT failures are becoming more frequent, rather than less, despite advances in technology.

Although the payouts may be welcomed, customers will still be aware that unless something is done about the failing IT systems from underlying legacy banking infrastructure that keeps crashing, they’re still at risk of it happening again.

Unclear How to Claim Compensation

While Barclays and others have vowed that no customer will be left out of pocket, the process of claiming compensation still remains unclear for many. Some have already lodged formal complaints, while others may need to wait for banks to proactively contact them about payments.

The Wider Impact on the Banking Industry

This wave of IT failures, and the subsequent compensation payouts, has put the UK banking industry under renewed pressure to modernise its digital infrastructure. Thankfully, the Treasury Committee has made it clear that more needs to be done to reduce the frequency of these failures, and banks are now being urged to make urgent investments in:

– IT resilience – ensuring systems are robust enough to handle peak usage periods.

– Third-party oversight – many failures stem from external suppliers, raising questions about regulation.

– Customer communication – better transparency when outages occur and clearer processes for compensation.

The government has already hinted that further regulation may be on the horizon, with a Treasury spokesperson stating: “We are working with the financial authorities to regulate third-party suppliers, as well as considering whether the banks are doing all they can to provide the level of service customers expect.”

What Does This Mean for Your Business?

The banks now find themselves at a crossroads. While the compensation payments acknowledge the impact on customers, they do not solve the deeper issue of unreliable IT infrastructure. For customers, the payouts may soften the blow, but they will do little to restore long-term confidence unless meaningful action is taken to prevent future disruptions.

For businesses, the implications of these failures are always far-reaching. For example, many companies rely on seamless banking operations to pay staff, manage cash flow, and complete critical transactions. Therefore, when banking systems go down, the knock-on effects can be severe, potentially leading to delayed wages, operational disruptions, and financial uncertainty. Small businesses, in particular, can struggle to absorb these setbacks, making banking reliability an essential component of economic stability.

The industry’s response to this crisis will shape the future of banking in the UK. If banks commit to modernising their IT systems and prioritising customer service, they may yet rebuild trust. However, continued failures could prompt stricter regulatory intervention, higher penalties, and increased competition from digital-only banks that have so far proven more resilient. With technology at the heart of modern finance, institutions that fail to adapt may find themselves losing not just customers, but also their position in the market.

As pressure mounts, it seems that banking in the UK is at a kind of turning point, and the coming months will determine whether these institutions can step up to meet the expectations of the businesses and individuals who depend on them every day.

In this Tech Insight, we look at the latest AI developments, including AI agents creating their own language, Opera’s new AI-powered browsing assistant, and a growing debate over the risks of an international race to artificial general intelligence.

AI Agents Are Speaking Their Own Language

A new experiment called ‘GibberLink’ has just demonstrated an intriguing concept, i.e. AI voice agents that can recognise when they are speaking to another AI and then switch to a more efficient communication method (which is incomprehensible to humans). Developed at a hackathon in London by Meta engineers Boris Starkov and Anton Pidkuiko, GibberLink replaces human-like speech with GGWave, a sound-based protocol that allows AI systems to exchange information faster and with less computing power.

To human ears, the communication sounds like a series of beeps and boops, reminiscent of dial-up internet modems from the 1980s. While it may seem like a niche experiment, the technology could actually have real-world applications. For example, as companies increasingly deploy AI-powered customer service agents, there may be a need for them to communicate directly. By using this machine-native ‘language,’ AI agents could cut computing costs significantly, making AI-driven voice interactions cheaper and more efficient.

The apparent viral success of GibberLink has sparked both fascination and concern. For example, some fear that AI developing its own incomprehensible communication methods could reduce transparency and accountability. However, Starkov and Pidkuiko insist their project is simply an experiment, and they have open-sourced the code rather than commercialising it (at least for now).

Opera’s AI Assistant Could Change How We Browse

It seems that Opera, the long-standing web browser, is aiming to redefine internet browsing with its AI-powered feature called ‘Browser Operator’. Unlike traditional AI assistants that simply summarise search results, Browser Operator actively completes tasks for users. For example, if you need to book a flight, it’s just a case of providing a few details, and the AI will search, compare prices, and add the best option for you.

What sets Opera’s AI apart from competitors like OpenAI’s Operator and Anthropic’s Claude is that it operates locally within the browser. This ensures not only faster performance but also better privacy, as user data never leaves the device. Unlike cloud-based AI tools, which require remote servers to function, Browser Operator processes requests directly on the user’s machine.

The potential benefits are clear, i.e. more efficient browsing, time saved on repetitive online tasks, and a more seamless digital experience. However, as with any AI-driven automation, questions remain about how much control users will ultimately have over decisions made on their behalf. Opera has included safeguards, allowing users to pause or cancel tasks at any time, ensuring that humans remain in the loop.

Eric Schmidt Warns Against an AI Arms Race

Amidst the rapid AI advancements, former Google CEO Eric Schmidt and two co-authors, Alexandr Wang and Dan Hendrycks, have just published a policy paper warning against a US-led push for artificial general intelligence (AGI). It seems they’re concerned that an aggressive AI race could provoke international retaliation, particularly from China, and potentially destabilise global relations.

Schmidt and his colleagues argue that the pursuit of AGI (a hypothetical AI system with intelligence surpassing human capabilities) should not be treated like the Manhattan Project, the US government’s programme to develop nuclear weapons in the 1940s. Instead, they propose a more cautious strategy, advocating for ‘Mutual Assured AI Malfunction’ (MAIM), which suggests that governments should focus on defensive measures to deter AI-driven threats rather than escalating an AI arms race.

The paper challenges the notion that the US must ‘win’ the AGI race, arguing that such thinking could lead to dangerous consequences, including pre-emptive cyberattacks from adversaries. Instead, they suggest limiting access to powerful AI chips, strengthening cybersecurity, and ensuring AI remains under human control.

What Does This Mean for Your Business?

These developments show just how rapidly AI is reshaping industries, and why businesses need to stay ahead of the curve. The rise of AI agents like GibberLink suggests a future where automated systems could interact more efficiently without human intervention. While this might reduce costs, businesses relying on AI-driven communication must consider transparency and ethical oversight to maintain customer trust and regulatory compliance.

Meanwhile, Opera’s Browser Operator signals a shift in how AI can automate everyday digital tasks. For businesses, this could mean exploring ways to integrate AI-powered automation into their workflows to improve efficiency. Whether it’s customer service, e-commerce, or operations, AI-driven task completion could actually free up human employees for more strategic work. However, as with any AI system, companies will need to carefully manage data privacy concerns and ensure these tools remain user-controlled rather than fully autonomous.

Also, the debate over AGI development highlights broader implications for businesses investing in AI research. If governments take a more defensive stance, regulations around AI chips and open-source models could tighten, limiting access to cutting-edge AI innovations. For businesses in cybersecurity, cloud computing, and AI ethics, this could create new opportunities (but also new risks). Understanding the shifting regulatory landscape will be critical for companies looking to leverage AI without falling foul of future legal constraints.

The main message here is, therefore, that as AI continues to evolve, businesses that can embrace its efficiencies while maintaining ethical and regulatory oversight are likely to be best positioned for long-term success. Whether integrating AI assistants, automating customer interactions, or staying informed on global AI policy, companies that adapt strategically will stay competitive in an increasingly AI-driven world.
