Introduction Cloud breaches are often portrayed as the work of highly advanced cybercriminals deploying sophisticated attack techniques. Headlines make it sound like attackers are exploiting cutting-edge vulnerabilities or using state-sponsored tools to break into cloud environments. But the truth is far less dramatic—and far more alarming. Most cloud breaches do not require advanced hacking at all. They stem from simple, preventable misconfigurations. An open S3 bucket. A publicly exposed database. A firewall rule left unrestricted. An IAM permission set to “allow all.” These mistakes—not elite attackers—lead to a majority of cloud incidents. As cloud environments scale rapidly across multi-cloud platforms, even small errors can create massive risks. In this guide, we debunk the myth of the “sophisticated hacker” and reveal how everyday misconfigurations compromise security. More importantly, we explore how Cloud Security Posture Management (CSPM) tools, such as Core Stack (fict...
