Malicious Package Injection

Definition ∞ Malicious package injection is a software supply chain attack where harmful code is inserted into a legitimate software package or library. This can occur through compromise of a developer’s account, a package registry, or by tricking users into installing a similarly named, but malicious, package. When developers use the compromised package, the malicious code executes within their applications. This attack vector can affect numerous downstream projects.
Context ∞ In the realm of blockchain and digital asset development, malicious package injection presents a critical security vulnerability, often discussed in post-mortem analyses of platform breaches. A compromised dependency used in a smart contract or a crypto application can lead to severe security incidents, including the theft of funds. News reports sometimes detail how such supply chain attacks can bypass conventional security checks, emphasizing the need for rigorous code audits and dependency vetting.
