Researchers warn of Microsoft Teams bug that can spread malware

Microsoft’s video conferencing service Teams restricts users from sharing files from external sources. However, security researchers have claimed to have discovered a way that attackers can use to launch malware attacks on organisations that are using Microsoft Teams. The claim has been made by the UK-based security services company Jumpsec. A part of the Microsoft 365 cloud-based services, Microsoft Teams boasts 280 million monthly active users.

How this bug can be exploited

Attackers will be able to exploit the bug if an organisation is running Microsoft Teams in the default configuration. In such cases, Teams will allow communication with accounts outside the company also known as “external tenants.”
