Dependabot helps automate the detection and fixing of security vulnerabilities in project dependencies. When an attacker disables this feature, they may be attempting to prevent the automatic detection of vulnerable dependencies, allowing them to exploit those vulnerabilities undetected. The target scope includes organizations using GitHub for their software development and version control. Identifying the disabling of Dependabot is crucial for security operations centers because it can be a precursor to more severe attacks, such as code execution or data theft through compromised software supply chains. This detection focuses on monitoring GitHub Enterprise logs for configuration changes that disable Dependabot functionality.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eInitial Access: An attacker gains unauthorized access to a GitHub account with sufficient privileges to modify repository settings.\u003c/li\u003e\n\u003cli\u003eReconnaissance: The attacker explores the repository\u0026rsquo;s settings to understand the available security features and their current configurations.\u003c/li\u003e\n\u003cli\u003eDisable Dependabot: The attacker navigates to the repository settings and disables Dependabot or repository vulnerability alerts.\u003c/li\u003e\n\u003cli\u003eDependency Manipulation: With Dependabot disabled, the attacker introduces or modifies vulnerable dependencies within the project.

Attackers could exploit these vulnerabilities, leading to code execution, data theft, or other compromises. Depending on the scope of the affected repository, the impact could range from a single application compromise to a widespread supply chain attack affecting numerous downstream users. The loss of integrity in the software development lifecycle can erode trust and lead to significant financial and reputational damage.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eIngest and monitor GitHub Organizations Audit Logs using the Splunk Add-on for Github (\u003ca href=\"https://splunk.github.io/splunk-add-on-for-github-audit-log-monitoring/Install/)\"\u003ehttps://splunk.github.io/splunk-add-on-for-github-audit-log-monitoring/Install/)\u003c/a\u003e.\u003c/li\u003e\n\u003cli\u003eDeploy the Sigma rule \u003ccode\u003eGitHub Organizations Disable Dependabot\u003c/code\u003e to your SIEM to detect when Dependabot is disabled in a GitHub repository.\u003c/li\u003e\n\u003cli\u003eInvestigate any alerts generated by the Sigma rule \u003ccode\u003eGitHub Organizations Disable Dependabot\u003c/code\u003e to determine the legitimacy of the configuration change.\u003c/li\u003e\n\u003cli\u003eEnforce multi-factor authentication (MFA) for all GitHub accounts to prevent unauthorized access as mentioned in references.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2024-01-03T12:00:00Z","date_published":"2024-01-03T12:00:00Z","id":"/briefs/2024-01-github-dependabot-disable/","summary":"A user disables Dependabot security features within a GitHub repository, potentially enabling attackers to exploit unpatched vulnerabilities in dependencies.","title":"GitHub Dependabot Disabling Detection","url":"https://feed.craftedsignal.io/briefs/2024-01-github-dependabot-disable/"}],"language":"en","title":"CraftedSignal Threat Feed — Dependabot","version":"https://jsonfeed.org/version/1.1"}
