  • •Hackers are using dormant GitHub accounts for corporate reconnaissance.
  • •The attacks leverage GitHub's API to gather public and private information.
  • •Organizations with GitHub repositories are at heightened risk.

Recent investigations revealed that hackers have been utilizing over 50 dormant GitHub accounts to conduct reconnaissance on corporate organizations, repositories, and developers. This activity leverages GitHub's API to gather public information, with some attempts made to access private source code repositories, resulting in rare successes. The campaigns have reportedly been active since at least October 2025. Organizations with significant GitHub presence are particularly at risk as attackers blend in using these dormant accounts. The full extent of the impact remains unclear, but the potential for data exposure is significant. Security experts recommend vigilance and proactive measures to secure GitHub accounts and repositories.
