HOWTO: Monitoring All Teamviewer Endpoints to Prevent Data Breaches


Any newly installed software on your company’s workstations can be the first alert indicating a data breaches at a very early stage. Monitoring all Teamviewer endpoints and proactively blocking all unauthorized installs it is a critical procedure that shall be performed by all departments on an ongoing basis.

TeamViewer - freeware software designed for remote administration, transferring files between multiple systems (including mobile), conducting presentations and visual training with a demonstration of the desktop, applications and individual files: due to the support of an enormous number of operating systems, a peep possible in every corner of the world without any settings!

Extremely popular, convenient and useful tool for organizing remote access was appreciated not only by system administrators and developers, but also by everyone who at least once had to urgently connect to a work computer during a business trip, vacation or from home. However, the uncontrolled use of such software poses a threat to the security of the company and may lead to incidents.

From the point of view of information security, Teamviewer endpoints are a threat to the perimeter violation of the corporate network - both in the case of Teamviewer uncontrolled use, and in the case of neglect of security rules when connecting to the corporate network from outside. At the same time, the activity of such software on the network significantly complicates the identification of malicious activity against a legal background. In addition, if there is no agreement on the use of remote access software with the IT security service, its detection on the network may indicate successful intruders.

To reduce the risk of such incidents, you should force security measures and limit the use of software for remote access as much as possible - for example, using application controls. In the case when the use of such software by employees is part of business processes, it is necessary to limit the potential of the potential attacker as much as possible. Thus, the use of HIPS policies, launch with minimal privileges, mandatory domain and, at best, two-factor authentication, will help reduce the risks of using potentially dangerous software to an acceptable level.

A lot of cyberattacks start with installation of new software. According to 2016 Verizon Data Breach Investigation Report (DBIR), a very common tactic used by intruders involves installation of remote control software , such as Team Viewer, Real VNC, join.me or LogMeIn. Quite a few registered attacks used email phishing techniques asking users to call an IT helpdesk to resolve a certain problem. When those users called a fictitious helpdesk, the cybercriminals picked up on the phone. Sounding very professionally, they asked users to install remote control software as the first step. Giving them installation URLs, they walked users through installation and then effectively took control of their computers as a stepping stone to accessing corporate files stored on a corporate network.
