Post Installation Script

Definition ∞ A post installation script is an automated sequence of commands or code executed immediately after a software application or package has been installed on a system. These scripts typically perform final configuration steps, set up environment variables, or install additional dependencies required for the software to function correctly. While essential for proper setup, malicious post-installation scripts can compromise system security. They complete the deployment process.
Context ∞ In the context of software supply chain attacks, crypto news has reported on instances where malicious post-installation scripts embedded in seemingly legitimate packages have been used to compromise developer machines or production servers. Such attacks can lead to the theft of private keys or the injection of backdoors into blockchain-related projects. Vigilant security practices and thorough vetting of all software dependencies are crucial to prevent these threats.
