Microsoft disrupts cybercrime operation selling fraudulent accounts to notorious hacking gang
Reporting on the same disruption noted that the fraudulent Outlook accounts were sold through a dedicated service and that a well-known intrusion group was among the buyers, using the accounts to support further attacks.
Microsoft and a fraud-prevention vendor disclosed the disruption of a group that Microsoft estimates created and sold roughly 750 million fraudulent Outlook and Hotmail accounts, together with automated CAPTCHA-solving services, to other criminal groups.
Market activity is an external indicator of abuse incentives, not a measurement of fraudulent accounts on the underlying platform. Prices are never inferred — an observation without a published figure is recorded without one. See the methodology for scoring and confidence rules.
