Password Cracking Team ‘CynoSure Prime’ cracked more than 11 million Ashley Madison’s passwords in just 10 days. Only 4.6 million passwords were unique, and the rest were such weak and horrible ones that one could even think. The team still left with 3.7 million passwords to decrypt. The top 5 most common passwords used were: ‘What’s your Wife Worth?’ and ‘How many people are Ashley Madison users?,’ according to a member of the team who shared the same list with few calculations.
