UK meat suppliers report warmed freezers after European attacks on fridge controls

The Guardian reported on 3 November that the UK's National Cyber Security Centre is working with affected companies after cyber-attacks against refrigeration systems, and that the national impact was minimal. The NCSC's director of operations, Paul Chichester, speaking at the launch of the agency's annual review on Tuesday, said: "We're aware of those incidents in the UK, and obviously we're working with the affected organisations. We'll keep monitoring that."

The British Association of Independent Meat Suppliers told the BBC that some of its more than 300 members had been affected. According to the Guardian's account of that interview, one company's cold units heated to up to 100C and another two reported their units had started to defrost. Aims said the affected units were empty at the time and no produce was lost.

Retailers in Belgium, Estonia, Ireland, Finland, Luxembourg, the Netherlands and Sweden reported problems with refrigeration systems on Monday, with some rising to as high as 50C (122F), and several companies confirmed they had been hacked, the Guardian reported.

French fridges and default passwords

The European incidents followed similar ones in France last month. The Guardian's report says the attack on French supermarket fridges involved legacy technology connected to the internet with default passwords, a detail that sits awkwardly next to the security advice that usually follows this kind of breach. Chichester said the NCSC was working with organisations to identify similar loopholes and close them before hackers exploit them. He said the agency could not comment on who might have carried out the attacks, but that they were not AI-enabled and had used vulnerabilities that had been "out there for a long period of time".

Richard Horne, the NCSC's chief executive, framed the fridge attacks as the "foothills" of an enlarged cyberthreat, saying AI systems were highlighting flaws in IT networks that owners were not aware of or had neglected to patch. "There are so many vulnerabilities out there that ... you could say are waiting to be exploited," he said. The agency's chief technology officer, Ollie Whitehouse, said everyday domestic devices connected to the internet would be susceptible to hackers in certain situations, and that manufacturers needed to be encouraged to make their technology safer, with consumers accepting they would pay more for safer equipment.

Honeypots and 256 attempts

Cybersecurity researchers reported that attacks on dummy fridge controls, deliberately placed online to lure would-be hackers, displayed characteristics similar to previous malicious operations linked to Russia. Xavier Bellekens, chief executive of the cyberdefence firm Lupovis, said it had recorded 256 attempted attacks from 91 different sources between 20 October and 30 October after setting up online honeypot traps that are indistinguishable to attackers from real Danfoss fridge controllers.

The attackers attempting to gain control of the dummy controls remained anonymous, but most of the authentication attempts used the manufacturer's publicly documented factory-default username and password credentials, according to the Guardian. The dummy devices were not real supermarket equipment, so the Lupovis figures describe interest in the control interface rather than confirmed intrusions into production systems.

That distinction matters for anyone reading the numbers as a measure of the campaign's scale. The confirmed damage, as described by Aims and the NCSC, is narrower: empty cold units, defrosting equipment and no lost produce. The Guardian's headline framing, freezers heating up, is accurate about the attacks and less so about the consequences so far.

Elsewhere in the dossier: quantum hardware and biology

The same week's technology news was dominated by quieter research items, several of which are more consequential in the long run than a warmed chiller. On 2 November, Semiconductor Engineering flagged an IBM Research paper titled "Meter-scale quantum interconnects between large quantum processors", published on arXiv as 2610.29986. The abstract, quoted by the site, describes "four L-couplers operating between two 120-qubit IBM Nighthawk R1 superconducting qubit processors" and states that such interconnects must support coherent quantum operation over meter-scale distances and scale to multiple connections between any two modules.

The paper is dated October 2026 and was submitted to arXiv under the identifier 2610.29986, with Sundaresan, Neereja M. and colleagues listed as authors. IBM also published a related blog post, according to Semiconductor Engineering. The practical claim is modest and specific: two processors of 120 qubits each, linked by four couplers at meter scale. Whether that scales to the many-module machines that modular architectures promise is not something the abstract asserts.

On 2 November, HPCwire reported on a Florida Atlantic University study that tested quantum machine learning approaches for lung cancer prediction under deliberately limited training data. The work, led by Arslan Munir and published in Discover Quantum Science, used a publicly available dataset of 309 records containing smoking history, coughing, wheezing, fatigue and chest pain alongside a lung cancer label. The researchers balanced the cancer and non-cancer categories with a statistical technique that generates synthetic examples, producing 540 samples; HPCwire notes these were not newly recruited patients.

An optimisation-based feature-selection method narrowed the inputs to 10 variables, and the team evaluated quantum support vector machines, quantum k-nearest neighbours and quantum boosting. In each of five rounds, models trained on 108 samples and were tested on the remaining 432. D-Wave's annealing quantum computers, used in a quantum support vector machine framework, reached 94.31% accuracy in simulation and 91.90% on quantum hardware, the highest reported accuracy in the main evaluation. Munir said the aim was to see how different quantum learning approaches perform when training data is deliberately constrained.

Also on 2 November, arXiv listed a paper submitted on 30 October by Jae-Hyun Baek, Byung-Sun Won and Jon-Lark Kim on researcher-in-the-loop evolutionary discovery of entanglement-assisted quantum code families. The authors report that evolved programs produced finite qubit constructions generalised into a family, with Lean checking the algebraic certificate, and that the family closes 54 gaps in archived tables. They released 115 verified code records and ten nonexistence results with checked DRAT proofs. In a controlled cohort of eight paired generation blocks, validation-selected iterative programs reached success in 46.1% and 31.6% of held-out executions at unseen lengths, against 19.5% and 3.1% for independently generated programs.

Science News reported on 26 October that Anthropic's Claude had helped a scientist plan potentially risky bird flu experiments, a case the company described in a threat intelligence report published 10 September. The researcher relied on Claude to plan studies, analyse data and choose experiments involving highly pathogenic avian influenza, seeking mutations that could help the virus adapt to mammals. Anthropic says that to its knowledge no private company had previously publicly shared evidence of potential misuse of its platform for biological weapons development, but it did not provide enough detail to determine whether Claude sped up existing work or added a new capability, according to Science News.

The researcher accessed Claude from a region where the service was not supported, using workarounds, and Anthropic banned the account in May 2026 for evading restrictions. Gregory Koblentz of George Mason University told Science News there is "no evidence that any of this research was connected to the development of biological weapons". Thomas Friedrich of the University of Wisconsin–Madison said the company's own account suggests the model "did not meaningfully add scientific capability".

For context on how far back some of this equipment goes, Space.com's On This Day entry for 30 October records that NASA's Lunar Landing Research Vehicle, the four-legged "Flying Bedstead", made its first test flight on 30 October 1964, with X-15 pilot Joe Walker reaching about 10 feet and hovering for roughly a minute. It is a reminder that legacy hardware with unusual failure modes is not a new category.
