This allowed the risk actor to achieve entry to the affected buyer accounts and led to the export of a major quantity of buyer knowledge from the respective Snowflake buyer cases. The risk actor has subsequently begun to extort lots of the victims instantly and is actively making an attempt to promote the stolen buyer knowledge on acknowledged cybercriminal boards.
