US-based remote management and monitoring company SolarWinds suffered a very sophisticated cyber–attack that raised a lot of questions about security. While media think this was the work of foreign intelligence services, as of this writing, we don’t know who is truly responsible.

It was a complicated, thought out and carefully executed attack that was probably planned over the course of a year or more.
