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. DaveGrohl supports all of the standard Mac OS X user password hashes (MD4, SHA-512 and PBKDF2)[1][2][3] used since OS X Lion and also can extract them formatted for other popular password crackers like John the Ripper.[4] 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. While in distributed mode, it uses Bonjour to find all the server nodes on the local network and therefore requires no configuration.^[citation needed]
