Andrews: We can't go into too much detail about our metrics, but our team has demonstrated a measurable increase in effectiveness, improving by more than 35 percent in all its metrics year over year.

CSO: How does the increase in the use of technology for committing fraud change the job of detecting and investigating these cases?

Andrews: The technology underlying financial services has evolved very rapidly, and the ways to perpetrate financial crime have evolved, so it's a moving target. Given the virtual world, the criminals' modus operandi is to stay mobile, since they know that staying mobile reduces their exposure and risk.

Mobile and wireless technologies have dramatically improved skimming technology, for example. Once a criminal has or point-of-sale terminal, he no longer needs to retrieve the device to collect the stolen data; thanks to wireless technology, he can collect it from the safety of his car in the parking lot.

Also, rather than clustering fraudulent purchases in one location, where a rise in flagged transactions might be obvious, they try to make their fraudulent transactions less obvious by driving around a fairly wide area.
