CloudFox

CloudFox manages identifying exploitable attack paths in cloud infrastructure, a task that is often cumbersome and time-consuming for penetration testers and security professionals. This command-line tool is designed to provide situational awareness in unfamiliar cloud environments, particularly in AWS, Azure, and GCP.

Technically, CloudFox is modular, allowing users to run specific commands or execute a comprehensive set of checks with the aws all-checks command. It operates by leveraging read-only permissions to enumerate cloud resources, making it suitable for white box enumeration scenarios. For black box scenarios, it can be used with "found" credentials to silently check access levels without triggering alarms. The tool codifies various enumeration commands using tools like sed, awk, grep, and jq, making it portable and efficient.

Operationally, CloudFox requires careful consideration of permissions. It can work with custom policies that list every permission the tool uses, or with broader policies like the AWS SecurityAudit policy, although the latter may lack permissions for newer services. The tool does not create alerts or findings and does not check for compliance, focusing instead on manual penetration testing efficiency.

Key technical details include support for 34 AWS commands, 4 Azure commands, and 8 GCP commands, with plans for Kubernetes support. The tool is written in Go and can be installed via binary releases, Homebrew, or compiled from source. CloudFoxable, an intentionally vulnerable AWS environment, is also available to practice and demonstrate CloudFox's capabilities in a controlled setting.

However, there are operational limitations to consider. CloudFox may encounter errors in certain commands, and its effectiveness can be hampered by the permissions available to the user. Additionally, while it provides real-time enumeration capabilities, it does not offer historical analysis or compliance checks, which may require additional tools to complement its functionality.
