Which of the following involves changing data prior to or during input to a computer in an effort to commit fraud?

Data diddling specifically refers to the unauthorized modification of data at the point of input - before it is processed or stored by a system. It is a form of computer fraud where an insider or attacker changes values (such as financial figures or records) during data entry, making it a distinct attack category focused on input-stage manipulation rather than transmission or access.

Spoofing involves impersonating a legitimate user, system, or network entity to deceive targets, not modifying data at the input stage.

Eavesdropping refers to secretly listening to or intercepting communications between parties, which does not involve altering data.

Wiretapping is the interception of telephone or network communications in transit and does not describe changing data prior to computer input.
