Explanation

A syllable password attack is a combination of a brute force attack and a dictionary attack. wHaaat? are you serious? that is hybrid! --- Not quite. The difference is subtle and it makes a distinction on where it starts from. A Hybrid attack is based on a Dictionary. Then it adds and/or substitutes symbols, letters, etc to increase the possibilities beyond the list of words. The Syllable attack has more or a base in Brute Force. It tries smaller fragments of Dictionary words rearranged and combined into new forms (in a brute-force fashion). --> http://sankar-information-security.blogspot.com/2012/10/password-cracking-methods-most-password.html
