Typically, fuzzers are used to test programs that take structured inputs. This structure is specified, e.g., in a file format or protocol and distinguishes valid from invalid input.

What is fuzzing used for?

WHAT IS FUZZ TESTING? In the world of cybersecurity, fuzz testing (or fuzzing) is an automated software testing technique that attempts to find hackable software bugs by randomly feeding invalid and unexpected inputs and data into a computer program in order to find coding errors and security loopholes.

What is fuzzing why and when is it used?

Fuzz testing (fuzzing) is a quality assurance technique used to discover coding errors and security loopholes in software, operating systems or networks. It involves inputting massive amounts of random data, called fuzz, to the test subject in an attempt to make it crash.
