Reply to comment by abitrolly in Zero Days (2016) - Stuxnet, a piece of self-replicating computer malware that the U.S. and Israel unleashed to destroy a key part of an Iranian nuclear facility, and which ultimately spread beyond its intended target. [01:53:51] by Missing_Trillions

The program that generates bogus parameters for function calls. In that case values for Siemens controllers to set that will cause chaos in controlled hardware.

This is really not a context in which you would normally use the term fuzzer. Stuxnet did not "fuzz" these PLCs, it performed a series of specific steps to identify its targets and cause them to break.

A fuzzer is a tool which automatically feeds semi-random data to another program in order to discover anomalous behaviours.

Thank you. Not sure what this guy has been smoking but he's got some type of imaginary cyber security world built in his head.
