TeamViewer is available for Microsoft Windows, macOS, Linux, Chrome OS, iOS, Android, Windows RT, Windows Phone 8 and BlackBerry operating systems. It is also possible to access a machine running TeamViewer with a web browser. While the main focus of the application is remote control of computers, collaboration and presentation features are included.
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.
Encryption and security features
TeamViewer includes encryption based on 2048-bit RSA private/public key exchange and AES (256-bit) session encryption, two-factor authentication, enforced password reset on unusual activity and a listing feature for trusted devices (Whitelisting).
Remote service scams using TeamViewer
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 which has identified the victim's computer as being infected by malware, most often using the name of companies such as Microsoft. They then ask the victim to give them access to their computer by installing a remote control service, which can allow the attacker to infect the computer with malware or to delete or copy personal files. A Wired journalist investigating the scams was asked by a scammer to install TeamViewer. It was reported that ransomware programs were utilizing TeamViewer as a tool to obtain remote access to infected machines. In the UK, the ISP TalkTalk blocked many remote access tools to protect its customers from remote service scams. They remain blocked as of April 2019.
Account access misuse
In June 2016, hundreds of TeamViewer users reported having their computers accessed by an unauthorized address in China and bank accounts misappropriated. However, TeamViewer said that "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."
Following the reported misuse, TeamViewer went offline several hours due to a denial-of-service attack. The company published a statement on its website summarizing the events and giving guidance in how users can protect themselves. TeamViewer referred to previous LinkedIn, Tumblr, and MySpace security breaches where millions of email and password combos were hacked and the stolen login credentials were also valid for the TeamViewer accounts of the victims.
In July 2018, The Register reported the widespread use of TeamViewer in the BDSM scene for HD live video sessions following the observation that many posts on Twitter exist where these kind of services are offered.
