Computer criminals are, for the most part, well-educated and highly

intelligent, and have the analytical skills that make them valued

employees. The fact that computer criminals do not fit criminal

stereotypes helps them to obtain the positions they require to carry

out crimes. Being intelligent, they have fertile imaginations, and the

variety of ways in which they use equipment to their advantages is

constantly being extended. In addition to direct theft of funds, the

theft of data for corporate espionage or extortion is being widespread,

and can obviously have a substantial effect on a company’s finances.

Another lucrative scheme, often difficult to detect, involves

accumulating fractions pence from individual payroll accounts, with

electronic transfer of the accumulated amount to the criminal’s

payroll.

Sabotage is also an increasingly common type of computer crime.

Everyone in the computer business has heard of cases of a “time-bomb”

being placed in a program. Typically, the programmer inserts an

instruction that causes the computer to destroy an entire personnel

data bank, for example, if the programmer’s employment is terminated.

As soon as the termination data is fed into the system, it

automatically erases the entire program.
