A programmer included a routine into a payroll application
to search for his/her own payroll number. As a result, if
this payroll number does not appear during the payroll run,
a routine will generate and place random numbers onto every
paycheck. This routine is known as:
A. scavenging.
B. data leakage.
C. piggybacking.
D. a trojan horse.
Answer / guest
Answer: D
A trojan horse is malicious code hidden in an authorized
computer program. The hidden code will be executed whenever
the authorized program is executed. In this case, as long as
the perpetrator's payroll number is part of the payroll
process nothing happens, but as soon as the payroll number
is gone havoc occurs.
