If it does turn out to be apt-29, then this is a brilliant attack on their part because it would give them potential access to just about any environment that they could want to investigate.
However on second thought I think that the group is more interested in the source code to TeamViewer so that they can find their own vulnerabilities that they keep to themselves.
This is going to greatly escalate the stakes in the security world for all vendors. I can see a lot of vendor Management Programs becoming a lot healthier all of a sudden, for those that can understand the trend.
