DaveGrohl

DaveGrohl is a brute-force password cracker for macOS. It was originally created in 2010 as a password hash extractor but has since evolved into a standalone or distributed password cracker. It supports all of the standard Mac OS X user password hashes (MD4, SHA-512 and PBKDF2) used since OS X Lion and also can extract them formatted for other popular password crackers like John the Ripper. The latest stable release is designed specifically for Mac OS X Lion and Mountain Lion.
Attack Methods.
DaveGrohl supports both dictionary and incremental attacks. A dictionary attack will scan through a number of pre-defined wordlists while an incremental attack will count through a character set until it finds the password. When in distributed mode, it uses Bonjour to find all the server nodes on the local network and therefore requires no configuration.
