CrowdStrike®  Intelligence™ has been researching reports of widespread DNS hijacking activity since information on the attacks became publicly available earlier this month.1 The information allowed for the discovery of at least a subset of domains affected by this campaign. CrowdStrike can confirm that numerous organizations in sectors such as government, insurance, and civilian aviation, as well as internet service providers (ISPs) and infrastructure providers, were affected going back as far as February 2017.
