Postinstall Script Exploit

Definition ∞ A Postinstall Script Exploit is a security vulnerability that leverages code executed automatically after a software package is installed to gain unauthorized access or control. This type of exploit targets the scripts that run as part of the installation process, injecting malicious commands that can compromise the host system. It represents a supply chain attack vector, often impacting development environments.
Context ∞ In the realm of blockchain and digital asset security, postinstall script exploits pose a significant risk to developer tools and decentralized application dependencies. News reports sometimes detail how such exploits can lead to compromised private keys or unauthorized smart contract deployments. Developers must rigorously vet all software packages and their installation scripts to prevent these subtle yet dangerous system breaches.
