TeamViewer Credits Network Segmentation for Rebuffing APT29 Attack

Despite warnings from Health-ISAC and the NCC Group, the remote access software maker says defense-in-depth kept customers’ data safe from Midnight Blizzard.

In public statements on June 27 (reiterated today), the German maker of remote desktop software said, “[W]e keep all servers, networks, and accounts strictly separate to help prevent unauthorized access and lateral movement between the different environments. This segregation is one of multiple layers of protection in our ‘defense in-depth’ approach.”

Defense-in-depth is a set of basic techniques, including network segmentation, that the US government consistently urges people to implement. Others include network monitoring, multifactor authentication, and access control lists.
