Microsoft Teams, just like other video conferencing apps, has seen a growth in users owing to the coronavirus pandemic. Now, a new vulnerability surfaced that could have allowed hackers to take over an entire Teams roster.
Microsoft Teams is among the popular video conferencing services and has seen a rise in users owing to the coronavirus pandemic. But, with the increase in user base, comes an increased security risk. A new analysis of Microsoft Teams by information security company CyberArk found that user accounts were vulnerable to takeovers just by sharing a malicious GIF. This vulnerability is associated to the temporary access token created by Microsoft Teams at various points and can affect both the Teams desktop or web browser versions. However, Microsoft said it has addressed the issue and taken steps to keep its customers safe.
The vulnerability was spotted by CyberArk when it analysed how Microsoft Teams works. During the research, it was found that every time Teams is opened, the client creates a new temporary token or access token.
