GitHub Dependabot repository access changed
Description
AlphaSOC detected modifications to GitHub Dependabot's repository access configuration. This includes changes to which repositories Dependabot can access for dependency scanning and security updates, or modifications to its default access permissions. Such configuration changes determine which repositories receive automated dependency vulnerability alerts and pull requests for security updates.
Impact
Unauthorized changes to Dependabot access configuration can disrupt automated security monitoring and vulnerability management processes. Adversaries may disable Dependabot access to hide vulnerable dependencies from detection, or modify permissions to prevent security updates from being applied. In some scenarios, threat actors could potentially manipulate Dependabot's configuration to interfere with the software supply chain security posture of affected repositories.

Investigation and Remediation
Review GitHub audit logs to identify who modified the Dependabot configuration, which repositories were affected, and what specific access changes were made. Compare the current configuration against the previous approved settings and document any discrepancies. If unauthorized changes are confirmed, immediately restore Dependabot access to the approved configuration and review affected repositories for any missed security updates or alerts. Implement additional monitoring for Dependabot configuration changes and ensure proper access controls are in place for organization settings.
