Biggest cyber attacks in history
Billions of people have been the victim of cyber hacks and that number is expected to grow.
IBM X-Force head Wendi Whitmore tells FOX Business “nation-state actors are a huge component” of these attacks which impacted 8.5 billion people last year. She also notes there is so much stolen data floating around already that criminals are leveraging that without needing to hack an organization.
FOX Business takes a look at the largest cyber attacks in history.
