Walmart rolls out AI agents to transform shopping and operations

Walmart has unveiled four AI agents to ease the workloads of shoppers, employees, and suppliers. The tools, revealed at the company’s Retail Rewired event, include Marty for suppliers, Sparky for customers, an Associate Agent for staff, and a Developer Agent.

The retailer is leaning on AI as inflation, tariffs, and policy pressures weigh on consumer spending. Its agents cover payroll, time-off requests, merchandising, and personalised shopping recommendations.

Sparky is set to eventually handle automatic reordering of staples, aiming to simplify everyday restocking for households.

Walmart is also investing in ‘digital twins,’ virtual replicas of stores that allow early detection of operational issues. The company says this technology cut emergency alerts by 30% last year and reduced refrigeration maintenance costs by nearly a fifth.

Machine learning is further being applied to improve delivery-time predictions, helping to boost efficiency and customer satisfaction.

Rival retailers are making similar moves. Amazon reported a surge in generative AI use during its Prime Day sales, while Google Cloud AI has partnered with Lush to cut training costs.

Analysts suggest such tools could reshape the retail experience as companies search for ways to hold margins in a tighter economy.

Stethoscope with AI identifies heart issues in seconds

A new stethoscope powered by AI could enable doctors to identify three serious heart conditions in just seconds, according to UK researchers.

The device replaces the traditional chest piece with a small sensor that records both electrical signals from the heart and the sound of blood flow, which are then analysed in the cloud by AI trained on large datasets.

The AI tool has shown strong results in trials across more than 200 GP practices, with patients tested using the stethoscope being more than twice as likely to be diagnosed with heart failure within 12 months compared with those assessed through usual care.

It was also 3.45 times more likely to detect atrial fibrillation and almost twice as likely to identify heart valve disease.

Researchers from Imperial College London and Imperial College Healthcare NHS Trust said the technology could help doctors provide treatment at an earlier stage instead of waiting until patients present in hospital with advanced symptoms.

The findings, known as Tricorder, will be presented at the European Society of Cardiology Congress in Madrid.

The project, supported by the National Institute for Health and Care Research, is now preparing for further rollouts in Wales, south London and Sussex. Experts described the innovation as a significant step in updating a medical tool that has remained largely unchanged for over 200 years.

How local LLMs are changing AI access

As AI adoption rises, more users explore running large language models (LLMs) locally instead of relying on cloud providers.

Local deployment gives individuals control over data, reduces costs, and avoids limits imposed by AI-as-a-service companies. Users can now experiment with AI on their own hardware thanks to software and hardware capabilities.

Concerns over privacy and data sovereignty are driving interest. Many cloud AI services retain user data for years, even when privacy assurances are offered.

By running models locally, companies and hobbyists can ensure compliance with GDPR and maintain control over sensitive information while leveraging high-performance AI tools.

Hardware considerations like GPU memory and processing power are central to local LLM performance. Quantisation techniques allow models to run efficiently with reduced precision, enabling use on consumer-grade machines or enterprise hardware.

Software frameworks like llama.cpp, Jan, and LM Studio simplify deployment, making local AI accessible to non-engineers and professionals across industries.

Local models are suitable for personalised tasks, learning, coding assistance, and experimentation, although cloud models remain stronger for large-scale enterprise applications.

As tools and model quality improve, running AI on personal devices may become a standard alternative, giving users more control over cost, privacy, and performance.

India to host OpenAI’s new Stargate data centre

OpenAI is preparing to build a significant new data centre in India as part of its Stargate AI infrastructure initiative. The move will expand the company’s presence in Asia and strengthen its operations in its second-largest market by user base.

OpenAI has already registered as a legal entity in India and begun assembling a local team.

The company plans to open its first office in New Delhi later this year. Details regarding the exact location and timeline of the proposed data centre remain unclear, though CEO Sam Altman may provide further information during his upcoming visit to India.

The project represents a strategic step to support the company’s growing regional AI ambitions.

OpenAI’s Stargate initiative, announced by US President Donald Trump in January, involves private sector investment of up to $500 billion for AI infrastructure, backed by SoftBank, OpenAI, and Oracle.

The initiative seeks to develop large-scale AI capabilities across major markets worldwide, with the India data centre potentially playing a key role in the efforts.

The expansion highlights OpenAI’s focus on scaling its AI infrastructure while meeting regional demand. The company intends to strengthen operational efficiency, improve service reliability, and support its long-term growth in Asia by establishing local offices and a significant data centre.

Salesforce customers hit by OAuth token breach

Security researchers have warned Salesforce customers after hackers stole data by exploiting OAuth access tokens linked to the Salesloft Drift integration, highlighting critical cybersecurity flaws.

Google’s Threat Intelligence Group (GTIG) reported that the threat actor UNC6395 used the tokens to infiltrate hundreds of Salesforce environments, exporting large volumes of sensitive information. Stolen data included AWS keys, passwords, and Snowflake tokens.

Experts warn that compromised SaaS integrations pose a central blind spot, since attackers inherit the same permissions as trusted apps and can often bypass multifactor authentication. Investigations are ongoing to determine whether connected systems, such as AWS or VPNs, were also breached.

Claude chatbot misused in unprecedented cyber extortion case

A hacker exploited Anthropic’s Claude chatbot to automate one of the most extensive AI-driven cybercrime operations yet recorded, targeting at least 17 companies across multiple sectors, the firm revealed.

According to Anthropic’s report, the attacker used Claude Code to identify vulnerable organisations, generate malicious software, and extract sensitive files, including defence data, financial records, and patients’ medical information.

The chatbot then sorted the stolen material, identified leverage for extortion, calculated realistic bitcoin demands, and even drafted ransom notes and extortion emails on behalf of the hacker.

Victims included a defence contractor, a financial institution, and healthcare providers. Extortion demands reportedly ranged from $75,000 to over $500,000, although it remains unclear how much was actually paid.

Anthropic declined to disclose the companies affected but confirmed new safeguards are in place. The firm warned that AI lowers the barrier to entry for sophisticated cybercrime, making such misuse increasingly likely.

Attackers bypass email security by abusing Microsoft Teams defaults

A phishing campaign exploits Microsoft Teams’ external communication features, with attackers posing as IT helpdesk staff to gain access to screen sharing and remote control. The method sidesteps traditional email security controls by using Teams’ default settings.

The attacks exploit Microsoft 365’s default external collaboration feature, which allows unauthenticated users to contact organisations. Axon Team reports attackers create malicious Entra ID tenants with .onmicrosoft.com domains or use compromised accounts to initiate chats.

Although Microsoft issues warnings for suspicious messages, attackers bypass these by initiating external voice calls, which generate no alerts. Once trust is established, they request screen sharing, enabling them to monitor victims’ activity and guide them toward malicious actions.

The highest risk arises where organisations enable external remote-control options, giving attackers potential full access to workstations directly through Teams. However, this eliminates the need for traditional remote tools like QuickAssist or AnyDesk, creating a severe security exposure.

Defenders are advised to monitor Microsoft 365 audit logs for markers such as ChatCreated, MessageSent, and UserAccepted events, as well as TeamsImpersonationDetected alerts. Restricting external communication and strengthening user awareness remain key to mitigating this threat.

Google Sheets gains smarter table conversion with Gemini

Last year, Google introduced ‘Convert to table’ suggestions in Sheets, allowing users to turn a selected data range into a formatted table with one click.

Now, Google has enhanced that feature with Gemini integration. When users accept a table suggestion, Gemini applies proper formatting and creates sensible names, such as ‘Project_Status’ or ‘Office_Expenses’, making formula references more precise and meaningful.

For example, users can write =SUM(Office_Expenses[Amount]) instead of cryptic cell ranges like =SUM(E2:E15).

These newly named tables offer dynamic formula ranges that automatically expand or shrink as rows are added or removed, helping spreadsheets stay accurate without manual edits. The feature can be turned off under Tools > Suggestion controls if users prefer their original workflow.

Rollout is underway for Google Workspace Business Standard/Plus and Enterprise plans and Google AI Pro, Ultra, and specific education add-ons.

Rapid Release domains are receiving it now. Scheduled Release domains will see it from 12 September. Admins must enable innovative features and personalisation for users to access them.
