FBI blames intrusions on improperly configured SonarQube source code management tools.

FBI officials say that threat actors have abused these misconfigurations to access SonarQube instances, pivot to the connected source code repositories, and then access and steal proprietary or private/sensitive applications.

Officials provided two examples of past incidents:

“In August 2020, unknown threat actors leaked internal data from two organizations through a public lifecycle repository tool. The stolen data was sourced from SonarQube instances that used default port settings and admin credentials running on the affected organizations’ networks.

“This activity is similar toa previous data leak in July 2020, in which an identified cyber actor exfiltrated proprietary source code from enterprises throughpoorly secured SonarQube instances and published the exfiltrated source codeon a self-hosted public repository.”
