The data breach that recently affected certain customers of Imperva's Cloud Web Application Firewall (WAF) product was made possible by a series of missteps as the cybersecurity company migrated to a cloud-based database service, the firm's chief technology officer disclosed yesterday in a blog post.

This key gave the attacker access to a database snapshot containing a variety of information on customers who had signed up for accounts through Sept. 15, 2017, but not afterwards.
