If you are using TeamViewer, then be careful and make sure you have applied the latest software update as you are threatened by hackers.
TeamViewer staff recently released a new version of software update patches which fixes severe vulnerabilities (CVE-2020-13699), which if exploited, could allow attackers to steal your system password by compromising it eventually.
What is more threatening is the fact that the attack can be carried out without requiring much interaction on the part of the “victim”.
This allows access to the SMB system by taking the system username, and the NTLMv2 hashed version of the user password, allowing them to enter your systems without compromising them.
Now, the victim’s Windows OS “will perform NTLM authentication when you open the SMB part and that request can be transmitted (using a tool as the responsibility) for code execution (or caught for HASHI cracking),” he quotes, among other things. TeamViewer team.
Please if you are a Windows user update your TeamViewer to the latest version 15.8.3 find it at this link .
