It shows that even low-skilled attackers can crack such passwords very easily, confirming that they offer very poor security. %G English %2 https://inria.hal.science/hal-01238600/file/crackmeimfamous.pdf %L hal-01238600 %U https://inria.hal.science/hal-01238600 %~ CNRS %~ INRIA %~ INRIA_TEST %~ INRIA-LORRAINE %~ LORIA2 %~ INRIA-NANCY-GRAND-EST %~ TESTALAIN1 %~ UNIV-LORRAINE %~ INRIA2 %~ LORIA-ALGO-TEST5 %~ LORIA %~ LORIA-ALGO %~ INRIA-CANADA
