Re: team viewer
""Our systems detected the suspicious activities in time to prevent any major damage," TeamViewer's comms director Martina Dier claimed in an email to The Register."
This can mean so many things...
i.e. we noticed our development/test systems were hacked when we had problems migrating things to production. Closer examination revealed that no production users were affected apart from old data we used for testing. We had not tools to monitor active attacks but fortunately stumbled upon this one. Hopefully things are better now.
Or it could mean they have robust systems in-place that detected the attack, notified staff who monitored the attack closely before shutting it down and ensuring systems were not affected by the attacks.
Given many of the publicised attacks over recent years, I would need evidence it was the latter as when details leak, it is typically the former.
