How Large Tech Giant Avoided Ransomware Disaster by Addressing Leaked AWS Key

Problem

CloudSEK's SVigil recently played a pivotal role in identifying a significant security vulnerability within the system of a leading financial and software services company. This case highlights the importance of robust security monitoring and proactive threat identification in safeguarding sensitive information and maintaining system integrity.

During a routine security audit, CloudSEK SVigil uncovered a critical security flaw rooted in the misconfiguration of a .git file. This oversight inadvertently exposed backend PHP source code, presenting a severe risk to the company's system. The exposed .git file made it possible for external actors to recreate and manipulate files and folders using readily available external tools.

Key Findings:

• Misconfigured .git File: The primary vulnerability stemmed from a misconfigured .git file that was publicly accessible. This file contained crucial backend PHP source code, which, if exploited, could have led to unauthorized access and potential data breaches.
• Exposure of Source Code: The misconfiguration exposed the backend PHP source code, providing malicious actors with insights into the system’s structure and functionality. This level of access could facilitate sophisticated attacks, including code injection and remote code execution.
• Recreation of Files and Folders: With access to the exposed .git file, attackers could use external tools to recreate and manipulate files and folders. This capability could lead to significant disruptions in the company’s operations, data integrity issues, and unauthorized access to sensitive information.

Solution

CloudSEK's Web App Scanner detected a major private bank's PII exposure due to a misconfigured web app on a third-party vendor. The team was alerted to correct the.git file, enhance repository access controls, and strengthen authentication, averting potential data breaches and safeguarding customer trust.

Impact

Compromised AWS credentials allow attackers to access and manipulate an organization's cloud infrastructure, including sensitive data and critical systems. This breach can lead to account hijacking, unauthorized configuration changes, and resource deletion. The resultant loss of infrastructure control poses severe security risks, including data breaches and operational disruptions, highlighting the need for robust cybersecurity measures.
