Microsoft Office 365 is a software package that includes cloud services, sold to corporates and private customers. The organizational package includes email, storage, social network, SharePoint and other services provided via cloud. Acquiring administrator’s access to organization that use Office 365 will provide a potential attacker with access to sensitive organizational information and may even lead to the threat actor gaining full control over the organization network.

Currently, 12 accounts are being offered for sale, with prices ranging from $15 for a logistics company account to $100 for a law firm. For each company, the seller provides a short description of the company, its country of origin, and which data the buyer will gain access to.
