CyberArk Labs finds vulnerability in Microsoft Teams
As we mentioned Microsoft Teams It is widely used these days. There are many users who are working remotely and make use of this type of services, as well as others who have also gained popularity such as Zoom.
However the important point is that these tools that can be used more now can also affect security. Ultimately, hackers set their sights on what has the most users to have a greater chance of success in achieving their goals.
This time from CyberArk Labs have found a critical vulnerability affecting desktop and browser versions of Microsoft Teams. This could lead to campaigns to steal user data. A fact that, as we see, puts privacy at risk.
They could also carry out ransomware attacks. As we know, this is a type of threat that seeks to encrypt the victims’ files and subsequently requests a financial ransom to enable them again and allow access. It is one of the most important problems we face online.
Additionally, this vulnerability can lead to corporate espionage. This bug takes advantage of a compromised subdomain and a Malicious GIF. This is sent to unsuspecting Microsoft Teams users and allows the attacker to collect information as indicated. Data that is related to that account.
Those attacks can spread to other Microsoft Teams accounts and groups in which the user is located. We already know that data on the web is of great value today. Many companies and platforms are looking for ways to collect data to later include users in spam campaigns, send targeted advertising or even sell them to third parties. But they can also use them to carry out cyber attacks.
No need to share GIF file
One of the most important problems with this vulnerability is that users do not need to share that GIF file to execute the attack. You would simply have to visualize it. This makes its spread faster and more automated.
Keep in mind that Microsoft Teams have already released updates to correct the problem. As we mentioned, it affected all users who use the desktop and browser version. It is important that we always have the latest versions to avoid this type of problem.
Therefore at RedesZone we advise Microsoft Teams users to install the latest version. This is something we always recommend on all types of platforms or systems.
