TeamViewer Admits Breach from 2016

The company says it stopped the attack launched by a Chinese hacking group.

TeamViewer, a German software company specializing in remote access and desktop sharing software, announced that it suffered an attack, presumably from a Chinese hacking group, in 2016. According to the company, the attack was discovered and stopped at the time, with no evidence of damage or compromise found.

The attackers used Winnti, a backdoor Trojan known to have been developed and used by groups located in China. Now used by multiple Chinese hacking groups, the software is considered a reliable indicator that the attack originated within China.

Prior to the Winnti attack, TeamViewer saw a campaign of attacks against user accounts among its customers. The German publication Der Spiegel reported that the Winnti campaign was active inside TeamViewer since 2014, a claim that, in an email message to Dark Reading, TeamViewer said was possible, though they said that the attack didn’t become active until 2016, at which point they stopped the activity before any damage occurred.

Re: Clarification-No Breach
Personally I consider at the lowest level unauthorized access a "breach" but you're right that in this case, what we typically call a breach - exposure of data, infestation - doesn't seem to have occurred.  Perhaps the breach spin is good, however, as it raises awareness of a weak network and security policy that likely encouraged a quick change in security processes by TeamViewer.  It also raises awareness - in security there is no "old news" as some readers may mistake this to be; any company that may have trojans or other compromising code hidden in its products needs to step up and convince us otherwise.  The question here is have they convinced us?

Clarification-No Breach
From the Read More: " found no evidence that customer data or other sensitive information had been stolen".... As such it would be a security incident and not a breach. Still alarming but not as detrimental to brand reputation based on how the company dealt with that incident.

Suspect indeed
For the past two years, our department has waged a campaign against Teamviewer because it was judged in-secure and now this article verifies our actions.  Remove it from all endpoints and systems.
