Industrial espionage takes two main forms: acquiring intellectual property like manufacturing processes and recipes, or sequestering proprietary operational information like customer data, pricing, and research. It involves activities like theft of trade secrets, bribery, and technological surveillance to gain commercial advantages. For example, in 1993 Volkswagen was accused of and later settled industrial espionage allegations after executives from GM's Opel division defected to Volkswagen, resulting in a $100 million settlement and agreement to purchase $1 billion in parts from GM over 7 years.
