Cyberattack threat: Corporate users infected via Microsoft Teams.
Researchers from Avanan, a Check Point company, have announced the discovery of attacks exploiting the Microsoft Teams communication platform to infect corporate users.
Microsoft Teams is a popular platform adopted by many companies worldwide, part of the Microsoft 365 family of products.
This platform allows its users to do audio and video conferencing, chat in multiple channels and exchange files between users and groups of users.
Very few users will care to save the obtained files on their hard drives and launch antivirus or threat detection products on it before opening them.
Enable two-factor authentication on the Microsoft accounts used for Teams so that users need to use a validation on their phones.
