Broadcom challenges Nvidia with Tomahawk Ultra AI networking chip

Broadcom has introduced a new networking chip designed to boost AI data centre performance, positioning itself against Nvidia in the AI hardware race.

Called Tomahawk Ultra, the chip helps link hundreds of processors within close range, ensuring fast communication vital for large AI models.

Instead of using Nvidia’s proprietary NVLink system, Broadcom’s Tomahawk Ultra operates on an accelerated version of Ethernet and connects up to four times more chips within a server rack.

The chip acts as a traffic controller, enabling what the industry refers to as ‘scale-up’ computing — where AI models tap into combined computing power from tightly grouped chips.

According to Broadcom senior vice president Ram Velaga, it took engineers around three years to design the Tomahawk Ultra, which was originally aimed at high-performance computing but adapted for AI workloads as demand surged.

Taiwan Semiconductor Manufacturing Company (TSMC) is producing the processors using its five-nanometre process, and the chips are already shipping to customers.

Rather than requiring major hardware overhauls, the Tomahawk Ultra offers a scalable, Ethernet-based alternative for AI firms looking to build faster, more flexible data centres.

Europe’s quantum ambitions meet US private power and China’s state drive

Quantum computing could fundamentally reshape technology, using quantum bits (qubits) instead of classical bits. Qubits allow complex calculations beyond classical computing, transforming sectors from pharmaceuticals to defence.

Europe is investing billions in quantum technology, emphasising technological sovereignty. Yet, it competes fiercely with the United States, which enjoys substantial private investment, and China, powered by significant state-backed funding.

The UK began quantum initiatives early, launching the National Quantum Programme 2014. It recently pledged £2.5 billion more, supporting start-ups like Orca Computing and Universal Quantum, alongside nations like Canada, Israel, and Japan.

Europe accounted for eight of the nineteen quantum start-ups established globally in 2024, including IQM Quantum Computers and Pasqal. Despite Europe’s scientific strengths, it only captured 5% of global quantum investments, versus 50% for the US.

The European Commission aims to strengthen quantum capabilities by funding six chip factories and a continent-wide Quantum Skills Academy. However, attracting sufficient private investment remains a significant challenge.

The US quantum industry thrives, driven by giants such as IBM, Google, Microsoft, IonQ, Rigetti, and D-Wave Quantum. Recent breakthroughs include Microsoft’s topological qubit and Google’s Willow quantum chip.

D-Wave Quantum has demonstrated real-world quantum advantages, solving complex optimisation problems in minutes. Its technology is now used commercially in logistics, traffic management, and supply chains.

China, meanwhile, leads in state-driven quantum funding, investing $15 billion directly and managing a $138 billion tech venture fund. By contrast, US federal investment totals about $6 billion, underscoring China’s aggressive approach.

Global investment in quantum start-ups reached $1.25 billion in Q1 2025 alone, reflecting a shift towards practical applications. By 2040, the quantum market is projected to reach $173 billion, influencing global economics and geopolitics.

Quantum computing raises geopolitical concerns, prompting democratic nations to coordinate through bodies like the OECD and G7. Interoperability, trust, and secure infrastructure have become essential strategic considerations.

Europe’s quantum ambitions require sustained investment, standard-setting leadership, and robust supply chains. Its long-term technological independence hinges on moving swiftly beyond initial funding towards genuine strategic autonomy.

AI Appreciation Day highlights progress and growing concerns

AI is marking another milestone as experts worldwide reflect on its rapid rise during AI Appreciation Day. From reshaping business workflows to transforming customer experiences, AI’s presence is expanding — but so are concerns over its long-term implications.

Industry leaders point to AI’s growing role across sectors. Patrick Harrington from MetaRouter highlights how control over first-party data is now seen as key instead of just processing large datasets.

Vall Herard of Saifr adds that successful AI implementations depend on combining curated data with human oversight rather than relying purely on machine-driven systems.

Meanwhile, Paula Felstead from HBX Group believes AI could significantly enhance travel experiences, though scaling it across entire organisations remains a challenge.

Voice AI is changing industries that depend on customer interaction, according to Natalie Rutgers from Deepgram. Instead of complex interfaces, voice technology is improving communication in restaurants, hospitals, and banks.

At the same time, experts like Ivan Novikov from Wallarm stress the importance of securing AI systems and the APIs connecting them, as these form the backbone of modern AI services.

While some celebrate AI’s advances, others raise caution. SentinelOne’s Ezzeldin Hussein envisions AI becoming a trusted partner through responsible development rather than unchecked growth.

Naomi Buckwalter from Contrast Security warns that AI-generated code could open security gaps instead of fully replacing human engineering, while Geoff Burke from Object First notes that AI-powered cyberattacks are becoming inevitable for businesses unable to keep pace with evolving threats.

Air Serbia suffers deep network compromise in July cyberattack

Air Serbia delayed issuing June payslips after a cyberattack disrupted internal systems, according to internal memos obtained by The Register. A 10 July note told staff: ‘Given the ongoing cyberattacks, for security reasons, we will postpone the distribution of June 2025 payslips.’

The IT department is reportedly working to restore operations, and payslips will be emailed once systems are secure again. Although salaries were paid, staff could not access their payslip PDFs due to the disruption.

HR warned employees not to open suspicious emails, particularly those appearing to contain payslips or that seemed self-addressed. ‘We kindly ask that you act responsibly given the current situation,’ said one memo.

Air Serbia first informed staff about the cyberattack on 4 July, with IT teams warning of possible disruptions to operations. Managers were instructed to activate business continuity plans and adapt workflows accordingly.

By 7 July, all service accounts had been shut down, and staff were subjected to company-wide password resets. Security-scanning software was installed on endpoints, and internet access was restricted to selected airserbia.com pages.

A new VPN client was deployed due to security vulnerabilities, and data centres were shifted to a demilitarised zone. On 11 July, staff were told to leave their PCs locked but running over the weekend for further IT intervention.

An insider told The Register that the attack resulted in a deep compromise of Air Serbia’s Active Directory environment. The source claims the attackers may have gained access in early July, although exact dates remain unclear due to missing logs.

Staff reportedly fear that the breach could have involved personal data, and that the airline may not disclose the incident publicly. According to the insider, attackers had been probing Air Serbia’s exposed endpoints since early 2024.

The airline also faced several DDoS attacks earlier this year, although the latest intrusion appears far more severe. Malware, possibly an infostealer, is suspected in the breach, but no ransom demands had been made as of 15 July.

Infostealers are often used in precursor attacks before ransomware is deployed, security experts warn. Neither Air Serbia nor the government of Serbia responded to media queries by the time of publication.

Air Serbia had a record-breaking year in 2024, carrying 4.4 million passengers — a 6 percent increase over the previous year. Cybersecurity experts recently warned of broader attacks on the aviation industry, with groups such as Scattered Spider under scrutiny.
