Microsoft Teams was vulnerable to GIF image-based attack

Users of Microsoft's Teams software need to ensure they're using the latest version of the software as Microsoft rolled out a patch last week that fixes an image-based hack that could lead to account takeover. Bleeping Computer writes the attack uses a regular GIF image and can give an attacker access to your account and your chat history. Check the site for details on how the attack is carried out. The vulnerability was discovered by security firm CyberArk. Microsoft says it hasn't found evidence of exploitation in the wild.
