According to German newspaper Der Spiegel, German software manufacturer TeamViewer suffered a breach at the hands of Chinese state-backed hackers, as a result of which the attackers have had access to TeamViewer’s internal network since 2014. The attackers allegedly used Winnti, a notorious backdoor Trojan.
While TeamViewer acknowledged that it was the “target of a cyber-attack,” the company claims to have “successfully fended off the attack,” and that an investigation into the incident “found no evidence that customer data or other sensitive information had been stolen, that customer computer systems had been infected or that the TeamViewer source code had been manipulated, stolen or misused in any other way.”
