Year on year, industrial espionage is resorting to ever more drastic measures. This fact is also reported by members of the German Federal Office for the Protection of the Constitution. Telephone, computer, and other telecommunications systems used by companies and public authorities are being spied on in an increasingly systematic and sophisticated fashion. And this is no longer something that only concerns major corporations and government agencies. Criminal activities are increasingly focusing on innovative medium-sized businesses, and medium and high-level authorities. This espionage is not only directed at new products, patents, or design drawings, but also at data about consortiums of bidders, bids, and invitations to bid.
