Trivy
Trivy is a comprehensive scanner for vulnerabilities, misconfigurations and secrets in container images, file systems, git repositories and infrastructure-as-code.
Legal & ethical use. Use this tool only on systems, networks and data that you own or have explicit written permission to test. Unauthorised access or scanning can break computer-misuse laws (for example Pakistan's Prevention of Electronic Crimes Act, 2016, and equivalents elsewhere). Practise in your own lab or in authorised environments such as CTFs.
