One of the main benefits of Teams is that it provides first-party integration with a company’s Office 365 subscription and also features extensions that can integrate with non-Microsoft products. This vulnerability worked just that way and had the potential to take over an organization’s entire roster of Microsoft Teams accounts.įor those of you who are unfamiliar with Microsoft Teams, it’s a leading communication and collaboration platform combining persistent workplace chat, video meetings, file storage, collaboration on files and integration with applications. An attacker sends a GIF or an image to a victim and gets control over their account. 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. Now, more than ever, these platforms are our “go-to” for almost everything from a simple chat with a team member to a company-wide all-hands meeting. These days everything is being done remotely – from job interviews to business meetings and even social gatherings. Teams, Slack or maybe Zoom? Which applications do you use? All are extremely popular with business users normally, but have been nothing short of essential during this “new norm” where businesses are working hard to stay connected to employees, customers and partners. CyberArk worked with Microsoft Security Research Center under Coordinated Vulnerability Disclosure after finding the account takeover vulnerability and a fix was quickly issued.This vulnerability would have affected every user who uses the Teams desktop or web browser version.Since users wouldn’t have to share the GIF – just see it – to be impacted, vulnerabilities like this have the ability to spread automatically.We found that by leveraging a subdomain takeover vulnerability in Microsoft Teams, attackers could have used a malicious GIF to scrape user’s data and ultimately take over an organization’s entire roster of Teams accounts.As more and more business is conducted from remote locations, attackers are focusing their efforts on exploiting the key technologies – like Zoom and Microsoft Teams – that companies and their employees depend on to stay connected.If this does not resolve the issue please contact our Customer Service Team. Once deleted, re-open CAM and you will be able to add new GIFs. Inside you'll find a folder titled "gifs."īefore deleting the GIF, close CAM, otherwise you may not be able to delete the file. To delete a GIF manually from CAM, you would need to search for %APPDATA% in your Windows 10 Search Bar, then find the NZXT CAM folder. If you are unable to load a different GIF, this may mean you would have to delete the file that is causing this problem. Sometimes when an incompatible GIF is uploaded, it can cause issues with loading other GIFs. ![]() ![]() There are a lot of different ways a GIF is encoded, sometimes making the GIF incompatible with the Kraken Z Cooler. Encoding is the process of converting data from one form to another. ![]()
