AI tools are increasingly used for simple everyday calculations, yet a new benchmark suggests accuracy remains unreliable.
The ORCA study tested five major chatbots across 500 real-world maths prompts and found that users still face roughly a 40 percent chance of receiving the wrong answer.
Gemini from Google recorded the highest score at 63 percent, with xAI’s Grok almost level at 62.8 percent. DeepSeek followed with 52 percent, while ChatGPT scored 49.4 percent, and Claude placed last at 45.2 percent.
Performance varied sharply across subjects, with maths and conversion tasks producing the best results, but physics questions dragged scores down to an average accuracy below 40 percent.
Researchers identified most errors as sloppy calculations or rounding mistakes, rather than deeper failures to understand the problem. Finance and economics questions highlighted the widest gaps between the models, while DeepSeek struggled most in biology and chemistry, with barely one correct answer in ten.
Users are advised to double-check results whenever accuracy is crucial. A calculator or a verified source is still advised instead of relying entirely on an AI chatbot for numerical certainty.

Korean Air has disclosed a data breach affecting about 30,000 employees. Stolen records were taken from systems operated by a former subsidiary.
The breach occurred at catering supplier KC&D, sold off in 2020. Hackers, who had previously attacked the Washington Post accessed employee names and their bank account details, while customer data remained unaffected.
Investigators linked the incident to exploits in Oracle E-Business Suite. Cybercriminals abused zero day flaws during a wider global hacking campaign.
The attack against Korean Air has been claimed by the Cl0p ransomware group. Aviation firms worldwide have reported similar breaches connected to the same campaign.

Aflac, a health and life insurer in the US, revealed that a cyberattack discovered in June affected over 22.6 million individuals. Personal and claims information, including social security numbers, may have been accessed.
The investigation found the attack likely originated from the Scattered Spider cybercrime group. Authorities were notified, and third-party cybersecurity experts were engaged to contain the incident.
Systems remained operational, and no ransomware was detected, with containment achieved within hours. Notifications have begun, and the insurer continues to monitor for potential fraudulent use of data.
Class-action lawsuits have been filed in response to the incident, which also affected employees, agents, and other related individuals. Erie and Philadelphia Insurance previously reported network issues linked to similar threats.

China is proposing new rules requiring users to consent before AI companies can use chat logs for training. The draft measures aim to balance innovation with safety and public interest.
Platforms would need to inform users when interacting with AI and provide options to access or delete their chat history. For minors, guardian consent is required before sharing or storing any data.
Analysts say the rules may slow AI chatbot improvements but provide guidance on responsible development. The measures signal that some user conversations are too sensitive for free training data.
The draft rules are open for public consultation with feedback due in late January. China encourages expanding human-like AI applications once safety and reliability are demonstrated.

Security researchers warn hackers are exploiting a new feature in Microsoft Copilot Studio. The issue affects recently launched Connected Agents functionality.
Connected Agents allows AI systems to interact and share tools across environments. Researchers say default settings can expose sensitive capabilities without clear monitoring.
Zenity Labs reported attackers linking rogue agents to trusted systems. Exploits included unauthorised email sending and data access.
Experts urge organisations to disable Connected Agents for critical workloads. Stronger authentication and restricted access are advised until safeguards improve.

US federal agencies planning to deploy agentic AI in 2026 are being told to prioritise data organisation as a prerequisite for effective adoption. AI infrastructure providers say poorly structured data remains a major barrier to turning agentic systems into operational tools.
Public sector executives at Amazon Web Services, Oracle, and Cisco said government clients are shifting focus away from basic chatbot use cases. Instead, agencies are seeking domain-specific AI systems capable of handling defined tasks and delivering measurable outcomes.
US industry leaders said achieving this shift requires modernising legacy infrastructure alongside cleaning, structuring, and contextualising data. Executives stressed that agentic AI depends on high-quality data pipelines that allow systems to act autonomously within defined parameters.
Oracle said its public sector strategy for 2026 centres on enabling context-aware AI through updated data assets. Company executives argued that AI systems are only effective when deeply aligned with an organisation’s underlying data environment.
The companies said early agentic AI use cases include document review, data entry, and network traffic management. Cloud infrastructure was also highlighted as critical for scaling agentic systems and accelerating innovation across government workflows.

European governments are intensifying their efforts to safeguard satellites from cyberattacks as space becomes an increasingly vital front in modern security and hybrid warfare. Once seen mainly as technical infrastructure, satellites are now treated as strategic assets, carrying critical communications, navigation, and intelligence data that are attractive targets for espionage and disruption.
Concerns intensified after a 2022 cyberattack on the Viasat satellite network coincided with Russia’s invasion of Ukraine, exposing how vulnerable space systems can be during geopolitical crises. Since then, the EU institutions have warned of rising cyber and electronic interference against satellites and ground stations, while several European countries have flagged growing surveillance activities linked to Russia and China.
To reduce risks, Europe is investing in new infrastructure and technologies. One example is a planned satellite ground station in Greenland, backed by the European Space Agency, designed to reduce dependence on the highly sensitive Arctic hub in Svalbard. That location currently handles most European satellite data traffic but relies on a single undersea internet cable, making it a critical point of failure.
At the same time, the EU is advancing with IRIS², a secure satellite communication system designed to provide encrypted connectivity and reduce reliance on foreign providers, such as Starlink. Although the project promises stronger security and European autonomy, it is not expected to be operational for several years.
Experts warn that technology alone is not enough. European governments are still clarifying who is responsible for defending space systems, while the cybersecurity industry struggles to adapt tools designed for Earth-based networks to the unique challenges of space. Better coordination, clearer mandates, and specialised security approaches will be essential as space becomes more contested.

The European Space Agency (ESA) has confirmed that a data breach occurred, but stated that its impact appears to be limited. According to the agency, only a very small number of science servers were affected, and these systems were located outside ESA’s main corporate network.
Claims about the breach began circulating on 26 December, when a hacker using the alias ‘888’ alleged that more than 200 gigabytes of ESA data had been compromised and put up for sale. The hacker claimed the material included source code, internal project documents, API tokens, and embedded login credentials.
ESA acknowledged the allegations on 29 December and launched a forensic investigation. A day later, the agency stated that its initial findings confirmed unauthorised access but suggested the scope was far smaller than online claims implied.
The affected servers were described as unclassified systems used for collaborative engineering work within the scientific community. ESA said it has already informed relevant stakeholders and taken immediate steps to secure any potentially impacted devices.
The investigation is still ongoing, and ESA has stated that it will provide further updates once the forensic analysis is complete.

The presidency of the Council of the European Union next year is expected to see Ireland lead a European drive for ID-verified social media accounts.
Tánaiste Simon Harris said the move is intended to limit anonymous abuse, bot activity and coordinated disinformation campaigns that he views as a growing threat to democracy worldwide.
A proposal that would require users to verify their identity instead of hiding behind anonymous profiles. Harris also backed an Australian-style age verification regime to prevent children from accessing social media, arguing that existing digital consent rules are not being enforced.
Media Minister Patrick O’Donovan is expected to bring forward detailed proposals during the presidency.
The plan is likely to trigger strong resistance from major social media platforms with European headquarters in Ireland, alongside criticism from the US.
However, Harris believes there is growing political backing across Europe, pointing to signals of support from French President Emmanuel Macron and UK Prime Minister Keir Starmer.
Harris said he wanted constructive engagement with technology firms rather than confrontation, while insisting that stronger safeguards are now essential.
He argued that social media companies already possess the technology to verify users and restrict harmful accounts, and that European-level coordination will be required to deliver meaningful change.

A hacker using the name Lovely has allegedly claimed to have accessed subscriber data belonging to WIRED and to have leaked details relating to around 2.3 million users.
The same individual also states that a wider Condé Nast account system covering more than 40 million users could be exposed in future leaks instead of ending with the current dataset.
Security researchers are reported to have matched samples of the claimed leak with other compromised data sources. The information is said to include names, email addresses, user IDs and timestamps instead of passwords or payment information.
Some researchers also believe that certain home addresses could be included, which would raise privacy concerns if verified.
The dataset is reported to be listed on Have I Been Pwned. However, no official confirmation from WIRED or Condé Nast has been issued regarding the authenticity, scale or origin of the claimed breach, and the company’s internal findings remain unknown until now.
The hacker has also accused Condé Nast of failing to respond to earlier security warnings, although these claims have not been independently verified.
Users are being urged by security professionals to treat unexpected emails with caution instead of assuming every message is genuine.
