Researchers Declare Microsoft Teams Unsafe

 Researchers Declare Microsoft Teams Unsafe



Microsoft's workplace-oriented messaging app, Teams, has faced a number of problems that you wouldn't expect other chat applications to face, such as last year when the Android app was blamed for disrupting the ability to make 911 calls on smartphones. The Teams app is back in the headlines.

Brief Overview: Microsoft Teams

Microsoft Teams is a collaboration and video conferencing tool that enables users to collaborate efficiently from home or the workplace.

The service enables users to connect by text chat, phone or video call, and it also integrates with a number of other Microsoft 365 services, including OneDrive and PowerPoint. Although Teams began as a corporate tool, Microsoft has lately marketed the platform as a consumer service as well, and has embedded it into the core of its new Windows 11 operating system.

Microsoft Teams' free edition provides a rich feature set that will suffice for many people and small enterprises, while a subscription version is offered for bigger organizations looking for a more complete solution. However, you may want to read further to decide if the app is actually worth it.

Teams Declared a Security Hazard by Researchers…

Vectra, a cybersecurity research group located in California, discovered a potentially catastrophic issue in the service's desktop edition, in which authentication tokens are kept in plain text, leaving them open to a third-party assault.

The problem affects the Teams app, which works on Windows, macOS, and Linux PCs and is built on the company's Electron platform. According to the research, an attacker with local or remote system access possibly steal these credentials. Microsoft is aware of the vulnerability, but it does not seem to be in a rush to address it.

According to Vectra, a hacker with the necessary access might grab data or clone it from an online Teams user and perhaps impersonate them while they're offline. This identity might then be used to bypass multifactor authentication (MFA) restrictions in programs like Outlook or Skype. Researchers advise users to avoid using the Microsoft Teams desktop software until a remedy is ready, or to use the Teams web service, which includes extra precautions.

While the Electron platform makes it simple to create desktop programs, it lacks essential security features such as encryption and system-protected file locations. Although Microsoft does not believe this framework to be a severe concern, security experts have consistently attacked it.

Given Microsoft's poor behavior and reluctance to resolve the issue, we recommend if you're concerned about your security, it may be better to leave the platform alone for a bit.
