wiredmikey writes from a report via SecurityWeek.Com: Microsoft is taking a step to better protect users by banning the use of weak and commonly-used passwords across its services. Microsoft has announced that it is dynamically banning common passwords from Microsoft Account and Azure Active Directory (AD) system. In addition to banning commonly used passwords to improve user account safety, Microsoft has implemented a feature called smart password lockout, meant to add an extra level of protection when an account is attacked. [Alex Weinert, Group Program Manager of Azure AD Identity Protection team explains in a blog post that] Microsoft is seeing more than 10 million accounts being attacked each day, and that this data is used to dynamically update the list of banned passwords. This list is then used to prevent people from choosing a common or similar password. Microsoft's new feature comes after last week's leak of 117 million LinkedIn credentials.
