Microsoft Teams is a leading communication and collaboration platform combining persistent workplace chat, video meetings, file storage, collaboration on files and integration with non-Microsoft products. The amount of data that goes into these applications is enormous and often includes confidential information from user names and passwords to top-secret business information making them prime targets for attackers. CyberArk worked with Microsoft Security Research Center under Coordinated Vulnerability Disclosure after finding the account takeover vulnerability and a fix was quickly issued. The vulnerability would have affected every user who uses the Teams desktop or web browser version.”]
