  • 55% of executives surveyed have been victims of social engineering
  • 25% of companies (especially small businesses) suffered losses that threatened their existence as a result of cyber attacks
  • Increased by 358% year-over-year (2020->2021) extortion incidents involving a failure of information, production systems, or disruption of operations
