Microsoft has introduced a new security feature for Teams, designed to prevent unauthorized bots from joining meetings, reports The Register. This 'bouncer' feature allows only approved bots to participate, enhancing the security of virtual meetings. This development is part of Microsoft's ongoing efforts to safeguard collaboration tools against increasing cyber threats.
For UK businesses, this enhancement is crucial as Teams is widely used for communication and collaboration. The ability to control bot access helps prevent data breaches and ensures that sensitive discussions remain secure. This update underscores the importance of securing digital collaboration environments against evolving threats.
This is a prompt for UK businesses to review their Teams security settings. Ensure that bot permissions are correctly configured and consider training staff on recognising unauthorized access attempts.

The Guardian reports that ministers are likely to support a law change allowing delivery robots on England's pavements. This regulatory shift could lead to widespread deployment of autonomous delivery robots, currently operating in a legal grey area. While this innovation promises efficiency in logistics, it raises safety and operational concerns.
For UK businesses, particularly in retail and logistics, this development could transform delivery operations, offering cost savings and efficiency gains. However, businesses must also consider the implications for pedestrian safety and potential regulatory compliance issues. The integration of such technologies requires careful planning and risk assessment.
For many organisations in logistics and retail, this is a prompt to explore the potential benefits and challenges of integrating autonomous delivery solutions. Consider the operational impact and necessary safety measures.

A malicious Chrome extension, posing as the AI search engine Perplexity, has been found intercepting user searches and address bar inputs, reports The Hacker News. This extension routed data through an attacker-controlled server before redirecting users to legitimate results. Google has since removed the extension following responsible disclosure by Microsoft.
For UK businesses, this incident highlights the ongoing risks associated with browser extensions. Such vulnerabilities can lead to data leaks and compromise sensitive information. Organisations must enforce strict policies on browser extension usage and regularly audit installed extensions for security risks.
This is a prompt to review and tighten policies on browser extension usage within your organisation. Conduct regular audits of installed extensions and educate users on potential risks.
