## The brief

Google Threat Intelligence and Mandiant say UNC6671 continued data-theft extortion after BlackFile's announced retirement, using several new brands while targeting financial and professional services. The report describes helpdesk impersonation and theft from enterprise cloud accounts, recommending phishing-resistant authentication and monitoring cloud activity. Shared infrastructure supports a connection between the brands, but the researchers acknowledge alternatives such as splinter groups or shared services.
