About this tag
The GitHub security tag covers incidents and features related to the security of GitHub-hosted repositories, particularly those owned by Microsoft and Azure. Recent content focuses on the Miasma malware campaign, where attackers compromised contributor accounts to plant credential-stealing payloads in Microsoft-owned repos, targeting AI coding tools and developer workstations. This campaign highlights the evolving attack surface where source control, AI agents, and cloud credentials converge. Other topics include GitHub's secret scanning enhancements for detecting active secrets like Azure tokens, and vulnerabilities in developer tools such as Gitk (CVE-2025-27614). The tag emphasizes supply-chain risks, credential theft, and the security implications of AI-assisted development workflows.
