In the last few days, there have been more and more reports that Microsoft Teams is being used to distribute malware. A detailed article can be found here, for example: Hackers Attach Malicious .exe Files to Teams Conversations (avanan.com).

In the past, email protection was one of the most important aspects for IT. In addition to browser access to the Internet, it was the easiest way to infiltrate malware into a company. As an extremely useful communication and collaboration platform, it is a logical conclusion that Microsoft Teams is now also not immune to attacks.

If you want to protect the platform from attacks, you should keep in mind that users are the most vulnerable point of Microsoft Teams. To protect yourself from the risk of data theft, we recommend the following measures:

• Enable users to participate in IT security training
• Activate security functions in Microsoft Teams (Safe links and Safe Attachments)
• Integrate additional security functions of the operating system (App Locker)

Another particularly relevant topic for protecting data in Microsoft Teams is identity protection. This enables identity-based risks to be identified, prioritized and dealt with. For example, Microsoft analyzes over 6.5 trillion signals every day and protects user data from potential threats in good time.

Paying attention to the following points will also help you to work securely with Microsoft Teams:

• Guest Management
• Guest access in teams
• Document classifications for sharing documents with external resources
• Chat and telephony functionalities with users outside the organization
• Chat and telephony for Skype Bridge and Teams Personal
