What is Storm-1152, alleged top creator of fake Microsoft accounts?

Microsoft has seized the websites of a Vietnam-based group it alleges sold millions of fake accounts to cybercriminals who used them for ransomware attacks, identity theft and other scams around the world.

The group, identified by Microsoft as Storm-1152, developed sophisticated tools to defeat the US tech giant’s security features to set up fraudulent Outlook and Hotmail email accounts in bulk.
