Step by Step Explanation: * Development of zero-day exploits is a critical risk, as adversarial entities with access to the source code could analyze it for vulnerabilities to exploit. * Legal action or sale of the source code are concerns, but they are not unique to the adversarial context of this scenario. * Publication of the source code on the internet is less likely than targeted exploitation in this specific scenario.
