Microsoft's Azure AD Sniffs Out Leaked User IDs and Passwords
Microsoft's Azure Active Directory Premium now alerts administrators when their users' passwords are being circulated around the dark corners of the Internet.Microsoft's Azure Active Directory (AD) Premium, the software giant's cloud-based user identity management platform, is on the lookout for leaked credentials that potentially could gain hackers a foothold in their networks and lead to a bigger security headache. David Howell, partner group program manager for the Identity and Security Services division at Microsoft, announced late Monday that his group has rolled out a new reporting option named simply Users with Leaked Credentials. Currently in preview, the feature lists users whose usernames and passwords have somehow slipped out of their grasp. Leaked username and password combos are a major source of aggravation for businesses. "In aggregate, [tens] of millions of credentials are exposed every month," blogged Howell. "Bad actors collect, sell, and share large lists of user account credentials from these breaches." Since folks often reuse the same password across several services, one set of credentials can act as a master key, of sorts. "Because three out of four users re-use credentials across multiple sites, there's a good chance that your users' credentials are in those lists," Howell cautioned.
To help businesses avoid spilling their secrets or other valuable information, Microsoft has been trawling the Web for the telltale signs of leaked passwords. "As part of running our consumer and enterprise identity systems, Microsoft discovers account credentials posted publically and we are making this information available to you so you can protect your enterprise when your users' account credentials are at risk," revealed Howell.
