Analysis & detection
What is Malicious Package Detection?
Catching deliberately hostile dependencies, such as typosquats, hijacked maintainer accounts, packages with install-time payloads.
This is a different problem from vulnerability scanning. A CVE is a mistake in legitimate code; a malicious package is an attack, often live for hours before removal, and frequently designed to execute during install rather than at runtime.
Because the window is short, detection depends on behavioural signals and fast-moving threat feeds rather than published advisories. A tool that only reads CVE databases will not catch this class at all.
Top 8 Malicious Package Detection tools
Every tool in the directory documented as supporting Malicious Package Detection, with what its own documentation says.
Support is not the same as parity, since some implementations are narrower in scope, gated to a higher plan tier, or maintained only for existing customers. The note under each tool is what its own documentation describes.
