A growing problem for companies is the presence of corporate moles - - employees who are stealing information and giving or selling it to outsiders (especially competitors).

Anti-fraud software maker Actimize conducted a survey on this issue, and included 40 large financial services firms in the U.S. and United Kingdom. About 50% of the companies surveyed said they believe they have had a corporate mole recruited and trained by outsiders to commit fraud. 85% of respondents said their company has been affected by employee fraud in general, and 65% think it is going to be a bigger problem in the future.

The 50% of companies that reported a data theft within the last 12 months have had losses averaging $875,000 per incident. The largest incident created $6 million in losses.
