Virtual Practice Lab
Practice Test


This lesson covers fuzzing which is very unique and only useful to security professionals. Fuzzing works by finding an application which takes input and starting sending data. You start fairly simply, misspelled commands, bad arguments and as you progress, you go larger by sending gigs of data or sending files with bits flipped to change the control paths. There are three types of fuzzing:

  • String mutation
  • Metadata/file format fuzzing
  • Malformed arguments

Participants also learn about password cracking, which is closely related to fuzzing. Password cracking involves simply trying lots of things quickly.
