Along with birthdays, names of pets and ascending number sequences, add one more thing to the list of password no-nos: good grammar. An algorithm developed by Ashwini Rao and colleagues at Carnegie Mellon University in Pittsburgh, Pennsylvania, makes light work of cracking long passwords which make grammatical sense as a whole phrase, even if they are interspersed with numbers and symbols. Rao’s algorithm makes guesses by combining words and phrases from password-cracking databases into grammatically correct phrases. While other cracking programs make multiple guesses based on each word in a database, putting in “catscats” and “catsstac” as well as just the word “cats”, none of the programs make the jump to combine multiple words or phrases in a way that makes grammatical sense, like “Ihave3cats”, for instance.
