TeamViewer is a proprietary software application for remote control, desktop sharing, online meetings, web conferencing and file transfer between computers.[7][8][9][10]


TeamViewer is available for Microsoft Windows, macOS,[11][12] Linux,[13] Chrome OS,[14] iOS,[15] Android,[16] and Windows RT[17] operating systems. It is also possible to access a machine running TeamViewer with a web browser.[18] While the main focus of the application is remote control of computers, collaboration and presentation features are included.[19]


The software is distributed by the German company TeamViewer AG, which was founded in Göppingen, Germany in 2005. As of 2018, TeamViewer has local representations in Australia and the United States.

Two outside investments were placed in TeamViewer since 2010. The Durham, North Carolina-based company GFI Software acquired a majority stake in TeamViewer in 2010. The London-based private equity firm Permira took over GFI's stake in TeamViewer in 2014.[20]

In 2020, TeamViewer software has seen significant extra demand caused by the COVID-19 lockdown and the shift of millions of people to remote work.[21]

In July 2020, Teamviewer agreed to acquire augmented reality firm Ubimax to expand its Augmented Reality (AR) and Internet of Things (IoT) offering.[22]


Remote service scams using TeamViewer[edit]

TeamViewer and similar services have been used to commit technical support scams via telephone calls. People are called, either at random or from a list, by criminals claiming to represent a computer support service that has identified the victim's computer as being infected by malware. Most often, the criminals pretend as if they represent well known software companies. They then ask the victim to give them access to their computer by installing a remote control service, which can allow the attacker to take over the computer in real time and infect the computer with malware or to delete or copy personal files or to pretend to have removed malware for which they charge a fee. A Wired journalist investigating the scams was asked by a scammer to install TeamViewer.[23][24] It was reported that ransomware programs were utilizing TeamViewer as a tool to obtain remote access to infected machines.[25][26] In the United Kingdom, the Internet service provider TalkTalk blocked many remote access tools to protect its customers from remote service scams.[27]

Account access misuse and possible breach[edit]

In June 2016, hundreds of TeamViewer users reported having their computers accessed by an unauthorized address in China and bank accounts misappropriated.[28] TeamViewer attributed the outcome to user's "careless password use" and denied all responsibility, saying "neither was TeamViewer hacked nor is there a security hole, TeamViewer is safe to use and has proper security measures in place. Our evidence points to careless use as the cause of the reported issue, a few extra steps will prevent potential abuse."[29]

Following the reported misuse, TeamViewer went offline several hours due to a denial-of-service attack.[30] The outage kept users from remotely logging into their computers. The company published a statement on its Web site summarizing the events and giving guidance in how users can protect themselves.[31] TeamViewer referred to previous LinkedIn, Tumblr, and MySpace security breaches where millions of email and password pairs were hacked and the stolen login passwords were reused by the TeamViewer accounts of the victims. Teamviewer also claimed in the same statement that they do "not store any password-equivalent data".[32] Throughout the ordeal, TeamViewer has maintained that it is not at fault for the account thefts. The company's handling of the matter has brought harsh criticism[33] from aggrieved customers, who accuse TeamViewer of being in "complete denial" of the problem. Following this event, TeamViewer launched additional security measures, namely Trusted Devices and enforced account password reset on unusual activity, to improve the security.

Adult services[edit]

In July 2018, The Register reported the widespread use of TeamViewer in the BDSM scene, following the observation that many posts on Twitter exist where these kinds of services are offered.[34]


Encryption and security features[edit]

TeamViewer includes encryption based on 4096-bit RSA private/public key exchange and Advanced Encryption Standard AES (256-bit) session encryption, two-factor authentication, enforced password reset on unusual activity and a listing feature for trusted devices (Whitelisting).[35]

Firewall and Port-forwarding[edit]

Configuration for port-forwarding and firewall is required in RDP, but TeamViewer doesn’t need port-forwarding or any configuration for the firewall.[36]
