A misconfigured backup file exposed sensitive customer data, internal credentials, cryptographic keys, and decompiled source code of a major bank—revealing how a single oversight can lead to a dangerous security spiral. Discovered by BeVigil during an infrastructure risk assessment, the breach highlights the urgent need for secure backup practices and continuous attack surface monitoring. Dive into the full report to understand how this exposure could have enabled identity theft, unauthorized access, and deeper system compromise.

What started as a single exposed Jenkins instance quickly snowballed into a full-blown infrastructure compromise—complete with remote code execution, leaked AWS keys, and customer PII exposure. In this real-world case uncovered by CloudSEK’s BeVigil, we break down how a seemingly minor CI/CD misconfiguration opened the floodgates for attackers. Dive in to see how the breach unfolded, the domino effect it triggered, and the critical lessons every organization must learn.
