How AI is used
npmscan is a security scanner designed to detect malware-like behavior in NPM packages, such as crypto-drainers and obfuscated scripts. Unlike traditional vulnerability scanners that focus primarily on known CVEs, this tool uses lightweight static analysis to find patterns associated with supply chain attacks.
It is built for developers and security leads who need to verify the safety of a package or a dependency list. The tool is cloud-based, allowing users to paste a package name or a package.json file to receive a risk summary.
Because it does not require login, API keys, or repository access, it may be used as a triage tool before adding new dependencies to a project. Buyers should note that while it identifies behavioral risks, it is designed for analysis rather than full-scale enterprise policy management.
The service is designed to be privacy-first; it reads and analyzes the provided data and then forgets it, without storing source code.
