Large digital security breaches are a common occurrence in the corporate world today. The latest breach, experienced by consumer credit reporting agency Equifax, follows a trend of troubling hacks that have played out across the globe this year. It seems adversaries will stop at nothing to evolve their threats, move with even more speed, and find new ways to widen their operational space.

Yahoo has revealed that up to 3 billion user accounts were hacked in 2013, tripling the number it said were affected by what was already the largest user data breach in history. The company previously said that up to 1 billion accounts were hacked in 2013, in addition to 500 million accounts being hacked in a separate incident in 2014.
